Tomato is a vegetable with strong light, and lack of light will cause flowers and fruits to fall. Protected field production can be hung on the north side of the greenhouse with reflective screens, and at the same time, it should be properly sparsely cultivated. The application of photosynthetic nutrient film fertilizer can help plants absorb a large amount of light fertilizer, light energy, light, compatible with conventional fertilizers, and nourishment for plant growth and development to the limit. One application benefits throughout the year. When planting, you should bring soil to avoid root injury, so as to slow down the seedlings and adjust the plants in time. During the growing period, it is possible to artificially adjust the growth and development balance through measures such as thinning flowers and fruits, pruning branches, and plucking leaves and toppings, and prevent diseases and insect pests in time to promote flower and fruit protection. After planting, pay attention to heat preservation, increase ground temperature and air temperature, and prevent injuries caused by low temperature. During winter and spring tomato cultivation, the seedling period should be maintained at 25 ° C during the day and 15 ° C at night to prevent excessive growth or the formation of aging seedlings. During the fruitful period, when the outside temperature rises, it is necessary to increase the ventilation to prevent high temperature hazards. Under sufficient light conditions, the indoor temperature of the shed during the day is 25 ° C to 26 ° C, the night temperature is 15 ° C to 17 ° C, the day and night ground temperature is 23 ° C, and the relative air humidity is 45% to 55%. Strengthen water and fertilizer management. Watering should be carried out with small water and frequent watering to avoid water accumulation in the field and prevent drought or excessive humidity in the soil. Adopt formula fertilization technology to ensure sufficient nutrition supply and avoid partial nitrogen fertilizer application. And spray the vegetable and fruit styling spirit once in the young fruit period and the swelling period to increase the water absorption and fertilizer absorption of the plant, improve the fruit yield and quality, reduce the fruit drop rate, and reduce the incidence of cracked fruit, dead fruit and deformed fruit.
