One, fertilizer, water-saving 1, from the cost-saving to reduce input and fertilization efficiency considerations, per acre application of chicken manure 10000 kg, 50 kg of urea, 50 kg of ternary compound fertilizer, which is the best amount of fertilizer in winter greenhouse vegetables. 2. With drip irrigation, the relative soil moisture content is 80%. Compared with conventional furrow irrigation, it can save 70.4% of water, which is of great significance for the development of vegetable facilities in the saline-alkali areas where agricultural water is extremely lacking. Second, the main technical regulations: 1. Introduce fine varieties. Choose middle and late ripe tomato varieties that are resistant to low temperature, low light, disease resistance, high yield and good quality. 2, nursery, colonization. The tomato seeds were soaked in water at 55°C for 10 minutes, then slowly lowered to 25°C to 30°C and soaked for 5 hours. Remove the drain and prepare the seedlings. When 5 to 6 leaves of seedlings are to be planted, the planting density is 2,000 plants per mu. 3, water and fertilizer management. With drip irrigation, when the relative soil moisture content is less than 80%, watering is performed to a relative moisture content of 100%. The results of the general period every 20 days topdressing once, each fertilizer can be controlled in the amount of urea per acre 5 to 10 kg, compound fertilizer 5 kg. 4, temperature management. After entering the result period, do not make the minimum temperature in the shed lower than 8°C. In the daytime, it may be properly ventilated if it exceeds 30°C. 5, plant adjustments. Single stalks are used for pruning to remove lateral branches at any time to ensure ventilation and light transmission in the field. Can be topping after the 5 ear fruit, in the upper part of the ear to select a strong lateral branch to replace the original main branch, can be left to 4 to 5 ear topping. 6, preserved fruit. Spray the flowers with the appropriate concentration of tomato spirits to ensure the fruit setting rate and artificial pollination.
