Cultivation techniques of Little Tomato

Cultivation Techniques of Tomato

Tomatoes are thermophilic vegetables, unlimited growth type, growth period can be as long as 6-10 months (well-equipped large greenhouses can reach more than 12 months), tall plants (more than 10 meters). Generally, it can be harvested 70-80 days after planting, with thick pericarp and excellent storage and transportation performance. And sweet mellow leaves, bright color (bright red). Cherry tomatoes 8-10 tons/mu, 10-15 g = single fruit (varies according to season and cultivation management level). Large tomatoes can reach 10-15 tons/mu in greenhouse, more than 150 grams/single fruit, and the highest yield recorded in Israel is 30 tons/mu, so it can be said to be an excellent variety in protected cultivation. It is also the main product of Hazera in the global market. 2. Planting preparation and cultivation management 1. Soil preparation: fine requirements, deep ploughing of land (40 cm), otherwise it is easy to form plough bottom layer, hinder water infiltration and salt diffusion, often make soil too dry or too wet, salt accumulation, affect root system deep penetration and development. Therefore, it is necessary to create a good rhizosphere environment to promote root development to the maximum extent, so that plants have excellent nutrient supply sources, which are prerequisites for high yield and good quality. 2, fertilization for the ridge: base fertilizer to use decomposed organic fertilizer 5000-8000 kg, the amount should be large, organic fertilizer spread after the re-tillage, in addition to the ridge, in the center of the furrow into the application of diammonium phosphate: 30-50 kg/mu, ditch depth should be 10 cm. Generally, high-ridge cultivation greenhouse is adopted in protection: (1) double-row planting (big and small rows): the width of the ridge surface is 80-100 cm, the width between the two ridges is about 50 cm, the height of the ridge is 15 cm, the plant spacing is 35-40 cm, and 1800 plants per mu, but no more than 2000 plants are appropriate. (2) Single planting: the width of the ridge surface is 50 cm, the width between two ridges is about 50 cm, the height of the ridge is 15 cm, the plant spacing is 35 cm, and 1800-2000 plants per mu. The plastic greenhouse adopts wide ridge double row planting, the ridge width is 90-100 cm, the plant spacing is 35-40 cm, and 2200 plants/mu. 3, planting (1) planting requires soil moisture, if the soil is too dry, irrigation should be about 3-5 days before planting (winter and early spring planting irrigation should be early to ensure sufficient ground temperature). (2) Digging holes: the depth of holes is the same as or slightly deeper than the length of seedlings. (3) Soil covering: generally flush with seedlings, not deep, or slightly cover seedlings with a layer of soil, if the film is planted, the film hole needs to be sealed with soil. (4) Irrigation: timely irrigation after planting, the amount of water should not be too large, generally about 10-20 cubic meters/mu. 4. Post-planting management:
