Work growing tomatoes in greenhouses, maintenance work for tomatoes in greenhouses.

April runs tomatoes in the greenhouse:
Leading environmental factors;
Weed control;
Copilitul;
Palisatul;
defoliation;
Stimulate fructification.


Leading environmental factors.
Natural light is conducted during September-April through glass clean to ensure a larger quantity of light. Beginning May heatstroke is reduced by spraying the emulsion opacifying glass (with clay, chalk or slurry of 20%).
The temperature in the greenhouse should be provided at least 16 degrees C at night and 18-22 degrees C day, according serenity sky. In fructification period cumprinsa air temperature must be between 22 and 25 degrees C.
Soil moisture should not fall below 65% of the water field capacity.
The relative humidity of the air in greenhouse tomatoes was maintained between 55-70%.
Ventilation in greenhouses intensifies when air temperature exceeds 20 degrees C, and continue all summer days. For routing the CO2 vent is a short-term when the temperature is lower. Ventilate on hot days is strong, the temperature should not exceed 30 degrees.

weed control
Where no herbicide was applied, will apply manual hoeing. Glasshouse conditions are very favorable for most weeds. Weeding degree in protected areas is much higher. Therefore it is necessary for 2-3 days before planting to apply herbicides.
The herbicide is applied before the operation of the plant are: Sencor 70WP at a dose of 0.3 to 0.5 l / ha TREFLAN EC 24 dose of 6 l / ha; Drevinol 45 F at a dose of 3 l / ha. Herbicides is incorporated immediately into the soil.

Copilitul
Copilitul side is executed when the shoots were 5-10 cm in length, the phase can be easily broken by hand. Copilii greater than 20-40 cm cutting production by up to 20%
In special circumstances the later crops in the greenhouse can keep a child with 1-2 blooms to increase production.
You can also use a child terminal 2-4 inflorescences to prolong harvests when conditions are favorable.


Palisatul
Normally sutinerea plants is the string of the string, which binds to the end of the base of the plant, about 10 cm from the ground and at the other end binds to the horizontal wire, AfaI used at 2 m height, providing a reserve stretch further.
It will consider the connection cord strain is not too tight. As plant growth they are twisted around the string, after two leaves, always be in the same direction.


defoliation
Defoliation begins with basal leaves, death, aging, ingalbenitite attacked by diseases and pests.
The ACES paper improves air circulation in the soil, which favors the homogenization of the air in the greenhouse.
Defoliation is made from the base of the plant up to 2-3 leaves in the inflorescence which has fruit 10-20 mm in diameter. As harvesting fruit blossom will advance and defoliation


stimulate fructification
The air temperature for the germination of pollen must be between 20-28 degrees C and the relative humidity of the air should be between 60-70%.
To use the vibrating mechanical pollinated plant by tapping with a stick or horizontal wires through electric vibrator. Vibrating increase production is 14%.
In order to improve the binding is applied to fruit-specific growth regulators: Tomafix dose of 0.03-0.05%; Tomatoset dose of 0.5 - 1% of; No - seed at a dose of 0.1%, 3% Tomatostim dose. Open flowers are bathed with a very fine spray. Increase of the yield by applying the regulators reach 10%.
Beds before planting in a week, the seedling will be treated with a dose of 0.1-0.15% Cycocel.
Grab amaturarii for fruit and tomato production growth early Ethrel apply (250-500ppm) phase penny. The treatment can be done after harvesting fresh fructelorin by bathing them in solution Ethrel (1000 - 2500 ppm)
