Modern technology for culturing red pepper in hothouses and greenhouses
To come to you with as much information about increasing peppers in greenhouses and solariums The following are our recommendations on this culture.
Culture of pepper in greenhouses / greenhouses is a crop year, with a long production cycle and therefore should be considered a special care in the first part of plant development (especially to first harvest).
seedling sites
To obtain highly productive crops, good quality and quality is essential as early seedling 's planting.
To obtain seedling 's pepper requires a dedicated space for creating optimal conditions for the development of seedlings - seedling Nita heated for winter sowing takes place.
A seedling pepper good quality required for annual crop must meet the following quality parameters:
1. Have aged between 60-80 days;
2. To see the floral button to Internode 0 (Internode) is Internode where the main stem begins development on several branches);
3 .Să have a height between 20-30 cm;
4 .Să be erect at planting (not bend after planting the brittleness of the stem);
5 to be free of viruses, diseases and pests (it is necessary to carry out treatments during the plant vegetation seedling s);
6. Do not present deficiencies of macro and micronutrients (requires root and foliar fertilization performing all along the seedling s);
7. Do not be etiolated;
8. Be vigorous and present a well-developed root system to fill the entire volume of the substrate;
9. Do not show mechanical damage from handling or any such damage;
10 .Să be turgid (not wilted to);
11. Be hardened;
Production seedling sites involves two process steps:
Sowing can be done in two ways:
1.Pe seedbed;
2. In the alveolar trays;
sowing
Planting peppers takes place in the first half of January, between January 2 to 20. In some regions (in the vegetable basin Jelly) sowing takes place even earlier (December 25 to 31) but such farmers have heating greenhouses / greenhouses after planting and also type of construction of greenhouses doubled by using the most modern film coating professional their enable early planting in early March with a minimal risk of freezing peppers.
Sowing is the seedbed or alveolar trays. In both cases, the seed substrate is peat EC specially treated to optimize pH's and with the addition of fertilizers. The requirements for a professional on the basis of peat substrate to be used in the production of seedling s in the first stage (seed-transplanters) are the following:
1. pH = 5.5 to 6.5; Always check that the packaging substrate to be mentioned pH and be between these values! Peat or substrate with pH values below 5 is for sowing!
2. the EC (electro-conductivity of the soil or soil salt concentration) is not less than 1 dS / m, preferably 0.6-0.8 dS / m;
3. Have the addition of NPK fertilizers and micronutrients; These additives are required in the first 2 weeks of feeding seedlings;
4. The particle size be between 0-10 mm is recommended that between 0-5mm!
5. The peat to be blonde, is recommended for seeding a mixture of peat and peat blonde black;
6. contain wetting additives; These additives are not mandatory but without them will be given greater care to irrigate constant substrate!
We recommend that sowing be done only professional substrate for sowing (technical specifications above) without any additives. If you still use and soil with peat forest land must be in any case of farms (of greenhouse own garden or field).
Using only the professional based on peat substrate for seeding has a number of advantages compared to the use of other substrates or mixtures:
| professional substrate | Earth or other mixtures |
| Free grass seed or insect | Seedy and insects may be present |
| Free of complex diseases " fall seedlings " | Increased risk of falling seedlings |
| pH and EC optimum germination and growth of seedlings sites | pH and EC varies depending on the source used |
| Added mineral perfectly optimized for the first part of developing seedling sites | Unknown mineral content |
| Getting seedling s uniform | Uneven emergence |
| Rich root development | Poor root development |
May also worth mentioning that the operation technological subculturing in the seedbed based on peat, roots seedlings do not suffer injuries imminent because grain very small peat and ease detachment as if they used ground breaking branches root young are practically unavoidable thus creating wider entry port for vascular disease and stress after subculturing in addition to young seedlings and fragile.
The parameters and conditions required for optimal germination of pepper seeds are the following:
1. optimum germination temperature range: 24 to 26 o C. The temperature for germination should not be less than 17 o C.
2. Humidity 100%
3. The complete absence of light in the first few days until the emergence (or non-coating paper board).
If the substrate is used for sowing professional technological operations are as follows:
1. The wet peat with water up to complete wetting;
2. Draw lines through a slight pressure to the substrate;
3. Place the seeds one at a time;
4. Cover the substrate with a thin layer of up to 0.5 cm (not more than pepper seeds for germination have little, or too much weight too high above the layer greatly delay the emergence);
5. They do not wet after sowing - due to the small grain of peat or subsequent addition of water leads to the discovery of seeds or their deeper burial. And in one case and the other will not be uniform emergence;
6. The paperboard is covered with papers or paper seedbed over which the foil can put a restraint role as long as the moisture necessary for germination of 100% and the optimum sweet răsării; Careful!!! This method foil seedbed coverage applies only to sow peppers in the winter when sunlight intensity is low and does not create problems peppers; especially during the spring and summer are not used in any form of seed coating film because it leads to choking and destruction of seedlings.
7. ensure a constant temperature day / night between 22-26 ° C but not more than 15 0 C; lower temperatures between 15-18 0 C affects not only irreparably peppers greatly delay germination and emergence (up to two weeks).
8. If temperatures are optimal after 4-6 days began to appear the first plant, and after the phenomenon of mass emergence occurs remove coatings to prevent elongation seedling sites emerged, even if emergence is not 100%.
All technological steps above respect and for drilling in alveolar trays marked as sowing in them is done with one single seed in each alveolar cell.
Advantages alveoli seed from the seed bed are:
1.Pot be left 7-10 days longer to subcultures (according to the number of cells / well can be left even more) distances between plants due to much higher than the seedbed (advantage deriving from this is economy heat is made by lengthening the time spent seedling sites nerepicate the same space smaller than the space occupied by seedling sites picked)
2.Rănirea the young roots subculturing operation is reduced to a minimum compared to the case in which the seedlings are taken from the seed bed of a plant root hairs which were interwoven with those of the neighbors;
3. Seedling is more robust due to the low density between plants;
4.Uniformitatea seedling sites is very good;
This method of sowing in alveolar trays has a disadvantage that the subculturing operation in pots will be a little more difficult, practically will take longer.
After emergence of the seedlings is necessary to change the complete constant day temperature / night temperature with alternating day / night, and it is necessary that during the day the temperature is between 24-26 0 C and 18-20 0 C. The night alternation is required for optimal development of seedling sites. A constant temperature day / night or a higher temperature during the night than during the day will result in accelerated growth of the strain (strain thin) at the expense of the plant mass represented by the leaflets, and thick stalk volume root. It also aims substrate moisture which will irrigate constant throughout the period until subcultures. With the irrigation and fertilization can be made and treatment plant must if sowing was done in the ground or mixed with soil. Fertilization is made in this period, compared with balanced mineral NPK fertilizer (20:20:20 Solufeed), the addition of magnesium and trace elements. Very small doses of fertilizers are 10-20 g / 10 liters of water (0.1 to 0.2%), in place of using 1 tablespoon NPK fertilizer (20:20:20 Solufeed) in a bucket of water. Also for the smooth development of the root system and a small stress resistance at the seedling sites may be used by wetting or spraying nimble at a dose of 10 ml / 10 liters of water. Phytosanitary treatments in this period include a fungicide against falling seedlings complex (to avoid the risk of phytotoxicity is recommended Previcur in dose 0.15% - this dose does not burn tip or young frunzuliţele), an insecticide against insects that occur immediately heated space where they like. We recommend as an insecticide for the first phase of development of seedling sites is Actara the dose of 0.02% - the benefits of using this insecticide related systemic cowardice its total and very importantly, the plant can get through the root system is easily transported peaks rise protecting plants efficiently and indoor precisely where it is most sensitive and which are most often attacked by insects, also reached peaks rising Actara induce an effect of biostimulation of meristems growth, an added advantage when used in early stages of development. If there is a risk of mites is recommended to use a acaricide like Vertimec or Milbeknock. One or two preventive treatment plant to subculturing is enough if there is observed symptom s disease or insect emergence in seedling Nita.
The note is referred and if the production of seed s is a space previously used for vegetable disinfection is imperative prior to the structure of the soil and primarily insects and mites! Disinfection may be a few days before sowing when heated seedling ned with an insecticide, acaricide ( Tal star for example) by spraying of the soil and the wood structure with a dosage of 2-5 times higher (which does not affect ) closes the space for an evening and / or one days then vented. Remember to follow rules and security measures (check and read the label before use) when applying toxic products!
bedding
The period between sowing and transplanters is 20-30 days depending on the temperature of the seedling Nita and the substrate used. Basically seedling is ready transplanters since it can be handled without risk of being broken or damaged during the subculturing operations. It is also good to have two true leaves well developed and well-developed root system. Repicatului delay inevitably lead to poor elongation strain and serious long-term negative effects on plants.
Sweet subculturing is required in the plastic mate pots, dark, light does not penetrate through the root. Note that the roots come into contact with light greatly reduce their loss to the specific functions of water absorption and nutrients! It should also be noted that, irrespective of the plants pricking out, a volume greater than the substrate it is always preferable to a volume less. To obtain seedling s pepper greenhouses / tunnels are recommended diameter round pots of 9 cm or 10 cm height as possible.
The substrate used for subculturing can be a mixture of peat forest soil, even the used sowing can be reused. If peat is used to improve the texture of the substrate and garden soil is used as an example (method widely used successfully in large pools vegetable); care must be taken that it be highly decomposed, with a very fine texture, be cattle or sheep (in any case in a bird !!!) and not to add excessive amounts (a 1 / 4 or 1/5 no adverse effects on the development of seedling s). Use of manure which is better for the substrate decomposed as a mixture of seedling lead to burn the roots, the emission of ammonia plants and little yellowing stop their growth. If garbage is poorly decomposed risk immediately after subculturing to drop all seedling sites due to release a large amount of ammonia (development induced wet garbage and high temperatures) in a very short time. For these reasons, to avoid risks caused by sources of manure or state of decomposition can be used successfully forest soil mixture substrate for seedling sites.
Immediately after subculturing to maintain a constant temperature day or the day / night of 24 to 26 0 C to reduce stress fast bedding and resume as soon as the development of the seedling 's. After these 2 days, returns to the alternating day / night temperatures. The difference between day and night temperatures should be 5-7 0 C, noting that should not be made at night or day temperatures fall below 7-8 0 C and a higher temperature at night than day will induce elongation of stems in damage normal vegetative growth.
Throughout the development of the seedling sites will be constantly track the plants watered, fertilized and treated for pests. As sowing space used for bedding seedling sites must be disinfected in the same way. Space disinfection prior to greatly reduce the risks of attack by insects on seedling sites. The presence of the seedling niţă a insects (thrips, whiteflies, muscular black) even in an extremely small number can cause major damage because these insect destroying, by feeding, in particular the tip growth (the most soft, juicy and sensitive seedlings in the development phase) of many seedling sites ( seedling 's have a much higher density than crops). How thrips feeding begins work at a temperature of 8 0 C, regardless of the season, the likelihood of such spaces is almost certain. For this reason we recommend that the first or second irrigation at the latest to use Actara protection seedling sites against such insects. Also 1-2 against falling seedlings Previcur treatments are recommended during this period (10-14 days of rest between treatments). As an alternative to Previcur can be used against falling Folpan Topsin or seedlings but with great care not to touch the tops sensitive seedling sites because there is great risk that they be destroyed after treatment if not properly conducted. If there is danger of mites and 1-2 treatments are recommended acaricides such as Vertimec or Milbeknock.
The application of fertilizer during this period is constant at each irrigation. Is used as a fertilizer NPK mineral fertilizer (20:20:20 Solufeed) equilibrated in the same concentrations as the seedling s (10 to 20 g / 10 liters of water). Also a very good root development may be used agronutrienţii (fertilizers, technical state of the art) such as nimble 0.1%, 0.2% and Calciamec Salwax / Alcaplant 0.2% . The use of these agronutrienţi induce smooth development of the root system, stem thickening, vigorous development of the vegetative nervous system, and also shortening of the internodes distances induce a higher resistance to stresses (cold, drought, disease attack, salinity, etc.).
With regard to the temperature conditions in this period (day increases, the light intensity increases, the outside temperature increases), if there are more than 35-40 0 C must be easy ventilation of the space in which it is seedling sites.
Also, if the pots were placed subcultures stuck together from time to time it is necessary to avoid lengthening their thinning in height seedling sites. When thinning is when the leaves begin to reach peaks adjacent to each other. Basin vegetable jelly (but also in other areas where conditions permit) there are technological thinning operation peppers, around 2-3 weeks before planting the beds down on the ground. This method gives farmers some clear advantages: a thinning very good seedling sites (leaves neighbors no longer touch each other and so each plant receiving exposure and a maximum of light, precipitating the rapid development), quenching optimal plant prior to planting (plants are placed directly on the ground, taking contact with the new environment) and, in addition, may work better. Of course this method requires a carefully increase in hand to maintain the optimum temperature (or at least minimum 7 0 C) to develop peppers, therefore this method is achieved where there are conditions: heating and film professional coverage. The period during which stay on the ground pepper pots is about 2-3 weeks until the conditions are fulfilled for planting in the ground. If it uses this method of thinning on the ground and pots used did not bottom roots seedling sites will grow deep into the soil (as the period is longer so and their growth will be faster) so planting the majority of these beams will be completely broken root leading to an enormous stress for plants, and the wounds are input to gates of all the diseases of the soil, worms including nematodes or wire. This injury to the roots of the transplanted plant disease is the leading cause of vascular diseases and infestation by nematodes and worms wire.
If the seedling sites increase in height and can not be planted there are several methods to slow the growth of the strain: deprivation of water to the extent of withering, deprivation of heat (but not less than 5 0 C), or using retardants growth.
transplantation
Several days before the transplant operation technology must:
1. quenching stresses seedling sites by the cessation of heating and ventilation of the space as tightly as seedling NITE;
2. foliar sprayed with fungicide and insecticide (preferably both at least a part of systemic A); by applying the seedling Nita saves time, pesticide, and water, and the plants will be protected at the time of planting of any foliar diseases.
3. Prepare the ground for transplanting - to loosen the tiller, to make holes for planting, to install a drip irrigation system;
4. Before planting any vegetable crops in hothouses and greenhouses is better to make a soil disinfection. The best method is disinfection about a month before planting Basamid. If you can not do with Basamid disinfection, and previous crop were recorded nematodes recommend a few days before planting soil application of nematicides products.
5. When using mulching, the transparent film mulch before planting to install all;
6. It is recommended that before planting to apply an insecticide against coropişniţelor, which would otherwise cause massive losses immediately after planting.
Density are planted peppers and brightness depends on climate zone. The recommended planting density peppers in greenhouses / tunnels is 30000-35000 plants / Ha. May be planted in rows with equal distance between them and the second most common method is to close rows (40-60 cm) and two spaced apart (1.0 - 1.2m). The distance between plants should be between 30-40 cm.

Irrigation and fertilization
Always before the establishment of vegetable crops it is recommended to perform the soil to revealing reserves of nutrients and organic soil on the one hand and on the other hand for the preparation of a rigorous and effective fertilization program properly.
In developing an efficient and optimal fertilization program to get maximum production and quality of a hybrid SC Marcoser SRL has the following parameters:
1. The analysis reveals the ground supply macro levels (N, P, K mainly) mezoelemente (Ca and Mg) and trace elements (Fe, B, Cu, Zn, Mn, Mo) where; also take into account two critical parameters are the pH (acid or basic reaction of the soil) and EC (electroconductivitatea or salt concentration of the soil);
2. Another parameter to be considered is the type of crop established, being known that different types of vegetables (peppers, cucumbers, peppers, eggplants, etc.) have different requirements in terms of macro and micronutrients level;
3. The planting season - due to the fact that during the cold season in the ground level although there may be optimal supply nutrients not available to plants when the soil is due to their cold properties (for example, phosphorus is an element such that although the present the availability in the soil for the plant roots decreases towards zero as the soil temperature of 10-12 0 C); Instead summer not only plants but all items are available due to strong mineralization of organic matter available nitrogen levels increase considerably;
4. cycle when the pepper crop in the greenhouse / solarium is for the most part long culture period, however, may be exceptions;
Although there are other parameters considered, but less relevant, knowing the above data are entered into a software of last generation that will generate a fertilization program strictly specific solarium from which the sample was taken for culture that It will be established. The results obtained following such a procedure may be 40% higher than the manuring "by ear".
If not conducted soil analysis fertilizers can be applied after a general plan that takes into account a lot of physiological peculiarities of culture established (required macro and micronutrients, phenophases own development vegetable species set). It also takes into account a level above the average of salts in the soil to prevent a possible salinity stress and supplemented phosphorus, calcium and potassium. Thus, as the basic fertilization is administered (preferably fall before plowing or digging) manure bovine or ovine semidescompus the dose of 60-80 tons / ha. The basic fertilization all add amendment of calcium (Dolomite) if the soil is strongly acidic reaction to increase the dose , and if the pH is above 7 to no longer recommended application. The dose per hectare of dolomite is about 3 tons / ha once every 3 years or 1 ton / ha per year. Another very appropriate amendment is superphosphate (single superphosphate if it is 20% is applied to 500 kg / ha). A part of the necessary nutrients are provided by culture of sweet basic fertilization, another part of the reserves of soil, fertilizers and the rest of the optimum development of plants is necessary to apply fertilizer during Phasial called the culture.
Phasial fertilizer application in fertilization is done by two methods:
1. Apply the root to the soil together with the irrigation water, the method called fertiirigare ;
2. Application by spraying, alone or in combination with certain pesticides (attention to the compatibility) - process called foliar fertilization ;
The administration of fertilizers during plant development should take into account the following aspects:
1. phenological phases of development of burn:-flowering plants, flowering internode 2 - the first harvest, the harvest 2 - Finally, etc;
2. Enhance natural processes of the plant while the environmental parameters are not conducive to optimal development of peppers: strong root development, induce flowering, increasing fruit, etc. These natural induction of certain developmental processes of plants are using non-hormonal agronutrienţilor date;
3. The rapid return of the plant as a result of the stresses incurred: transplantation, salt, cold, drought, heat, humidity, excessive attack of the disease, etc. Rapid return of the different stresses to plants is performed using the next-generation non-hormonal agronutrienţilor;
Considering all of the above SC Marcoser SRL can provide those interested a general plan for fertilizer application pepper grown in greenhouses / greenhouses.
Irrigation, with proper preparation of the soil before planting is one of the most important factors leading to the success of vegetable crops. Below are some basic principles regarding the irrigation of vegetables in hothouses and greenhouses:
1. The recommended method of irrigation pepper in hothouses and greenhouses is drip irrigation; (see advantages)
a. To ensure a flow rate of 1.6 to 2.5 L / h / dispensing water at a pressure of 0.5 to 1 atm;
b. To have the distance between the peaks of 20-30 cm (Note that the dropper is not a requirement that the base of the stem to be sweet, but drip line should be as close to the plant);
4. Watering should be done as often as possible, the recommended frequency is every day with some water combined with environmental conditions: fewer cold days and more on hot days;
5. Each Irrigation and fertilizers are added respecting the principle of "as much as possible in as small portions" (fertilization teaspoon); Such dosage recommended weekly will be applied daily in equal portions to the number of applications made - for example, if we apply one kg of a particular fertilizer on the week and the week will be five irrigation at each irrigation will apply 1: 5 = 0.2 kg fertilizer / irrigation. Thus the plant will use all the manure and will not suffer from shock saline due to large amounts of fertilizer application.
Phytosanitary treatment
As with other technological links and for pest control are some general principles to be respected regardless of protected crops or commercial products used. Pest control plans developed by SC Marcoser SRL are based on the principle that prevention of disease is less expensive than their control. The following are a few lines of guidance in using pesticides in their pest management:
1. Read the label and always follow the recommendations and security measures of the use of plant protection products;
2. The first part of plant development (after transplanting) is used fungicide is at least 2 components, one contact and one systemic complicated. The rationale for use of such compounds in period is given by the fact that the plants have an accelerated rate of vegetative growth (rapid growth), so that when using only the fungicide is the contact strength to protect them becomes 0 in tissues and newly formed organs, tissues and organs that can be adequately protected by a component of systemic complicated. Later, when the foliage is fully developed, the tips are broken in peppers with short cycle may be used with good results fungicide they contact;
3. And if insecticides and acaricides have chosen the same principle as in the case of fungicide met: systemic in the first part of development and systemic e / contact of the two;
4. Always alternate plant protection products; avoid using 2 or more times the same active substance; every application alternate substances with different modes of action to not create and increase resistance to pesticides pests. A plant protection product can be used as many times as recommended by the manufacturer during a culture condition that between two successive uses of the same product to be used and different product with a different mode of action;
5. phytosanitary treatments carried out for prevention and control are made at an interval of 7-10 days depending on the pressure of the incidence of the disease;
6. Do not use more than 3-5 active substances (Caution 5 5 not active and to a product produced may contain different substances and 3) a single application in order not to stress especially phytotoxic to plants when it is about substances systemically it is because the plant has a limited number of gateways regardless of the number of substances applied and the increase will lead to a blockage physiological leaf: phytotoxicity ;
7. The dosage of the active substances used are calculated based on the age of the plants and the treated surface and not on the amount of water used because it can vary within very wide limits due to the various machines is carried out by spraying (pump Vermorel , atomizers, sprayers, etc.). For example, since the third harvesting peppers will be used strictly dose recommended for surface regardless of the quantity of water used;
8. With the phytosanitary treatment and foliar fertilization can be provided the materials used are compatible.
SC Marcoser SRL elaborates complex pest by the above principles and advises agricultural professional in this field.
Other technological works
The most important technological links for growing peppers in greenhouses / tunnels posed management and trellising plants.
Driving
driving operation is represented by a variable number of retention arms (2, 3 or 4) that start from the main stem coupled with the removal of buds and flowers or twigs of the first internodes. Depending on the number of arms hybrid that starts from the main stem can be 2, 3 or more. The best results were obtained when the number of arms left were 2 or 3. Further up the next internode (portion where each left arm splits again) remove all arms in November leaving the only one arm. The operation to remove the new branches to internodes 2-4 is based on the hybrid used. If the hybrid is able vegetative great and generates unlimited new shoots are removed to 4th internode arms more in return if the hybrid generate a limited number of shoots when surgery to remove the arms additional stops at the second internode. In parallel with arms removing us at first internodes removed the flowers or buds at least from Internode 0, which is very important to eliminate even the floral bud stage; leaving the flowers to exploit will lead to degeneration behavior physiological plant by slowing vegetative growth and concentration plant on increasing fruit also decreases the development of root and these phenomena have serious consequences on the future development of the plant and thus a significant decrease productivity term long. Below are two examples:
Trellising
trellising sweet can be made by three methods:
1. The Netherlands (classical trellising is practiced in other cultures of tomato, cucumber, etc) in which each stem is supported over the entire height of a thread; If using this model trellising are three methods of attachment of the thread to support plant: use of a ring which secures the thread and the plant, the binding simply floss at the base of the plant or the binding thread of the pin which is in the ground around the plant. Whatever method is chosen trellising the thread of peppers for each main arm by turning periodically (depending on the rate of increase) of the arms around the thread. Thread used must be very thin because there is a risk that the plant is hurt by cutting the action of its own weight. The advantage of this method is to obtain fruit of extraordinary quality because most are on the main stem and disadvantages are volume the great job to be given by thread and copilirea periodically shoots that otherwise would break, not additional support;
2. The Spanish - the ends of the rows are fixed trellis wires which are attached to a side of the supporting plant. The distance between the wires is approximately 30 cm and is added during plant development. The advantages of this method are the amount of the reduced work for trellising and sprouts, and the disadvantage is the high cost of the infrastructure to support (trellis, wires, assembly, etc.). The model is not sustainable under the same solar practice crop rotation, tomatoes or cucumbers are another type of trellising necessary.
3. MODEL MATCA - is a combination of the two above methods adapted to local conditions. So after planting (after developing sufficient arms to allow even a twist of thread around it) using a system slightly modified and adapted for solariums model Dutch trellising (driving the main stem) - so it starts with coil whole threads of the first bell in a row, link to a node above the wire supporting, lower coil is intertwined lowering the first arm of the peppers and then descends further to the main stem, is wound / twisted together or twice (not done node) then raises the thread on the second arm of pepper, blends / turns and it once or twice depending on the length and raise the coil to the wire support, it gives after it (the node is not) and restart the process with the next peppers in a continuous system without the row nodes to the node where it binds to the wire thread Sustiva maintenance, cut the thread and resume the next time.
Defoliation
vegetative mass represented by the foliage of the plants is very important because it is factory or kitchen plants that produce all of the compounds necessary for the development of new tissues and organs, fruit growing, etc. Although it is very important to have a well developed leaf apparatus to support the feed as many fruits are cases where it is necessary to remove leaves - defoliation. There are several reasons why we recommend defoliation such as wilting and drying of leaves due to insufficient quantity of light that reaches them (this phenomenon often happens at basal leaves), need for ventilation strongest ground level in greenhouses / greenhouses with high humidity. If the bell pepper culture in hothouses and greenhouses is recommended to first internode defoliation after harvesting have fully completed the first internodes. Defoliation greatly helps in proper ventilation plant especially during hot.
Pollination peppers is recommended especially in the first part of the cycle in the spring, when due to adverse weather conditions pollination and binding are deficient causing production losses through abortion of flowers and the emergence of a large percentage of fruit deformed due to a small number of seeds fertilized fruit. Pollination is carried out by drones.
Harvesting
Harvesting peppers grown on qualifying in greenhouses and solariums is the maturity of the market which could coincide with the maturity biological sources (eg pepper red at first is dark green, and the green color) or can not be reached If maturity as yellow bell pepper, which harvested before actual cooking. Harvesting is done continuously at about 7 days throughout the development cycle or waves 10-14 days depending on the genetic characteristics of hybrids use. Practicing as frequent harvests lead to an increase in total production of pepper because immediately after removing fruit photosynthetic compounds produced large leaves are oriented fruit growing smaller. Also all the practice of crops as frequency and number of fruits increases due to abortion rates are low (allowing for a while as long fruits high in the plant prevent the transport of large quantities of food to the flowers and fruits, young causing a high rate of abortion, especially during hot and / or dry).
Attention and interest increase it is granted by Romanian farmers increasingly more culture red bell pepper type BLOCKY (capsicum professional baking from green to red).
Culture pepper professional red ripening from green to be among the most profitable crops in the moment in Romania for several reasons:
1. red bell peppers is a vegetable much appreciated by consumers due to taste very good and the concentration and very high in Vitamin C and Vitamin a (fruit of red pepper has the highest concentration of vitamin C of all vegetables practically 100 g red pepper ensuring 3 times the daily requirement of vitamin C and 110% of vitamin a);
2. At present over 98% of all consumption of red pepper sold in Romania is imported mainly from Spain, the Netherlands, Israel and Turkey, concluding that for a long time selling market in terms of profitability for farmers not It will be a major problem;
3. Because of high genetic value hybrids red pepper products Zera Gedera - the world leader in seed production of this - coupled with the implementation of a technology culture tidy application of a fertilization program specifically designed for this culture and application an integrated pest management (protection software) productivity and quality of the fruit obtained ensures a high threshold of profitability of the culture;
SC Marcoser SRL, testing and experimentation carried out over four years in many greenhouses and solariums in large pools vegetable accumulated rich experience by developing technology culture, creating programs optimal fertilization and effective countermeasures pest followed and managed to introduce successfully in hothouses and greenhouses in Romania professional culture red pepper, is a promoter of this culture in Romania.
