Supplement boron before flowering and calcium supplement after flowering, that is, apply boron fertilizer once before each flower is formed or opened, promote good differentiation of flower buds and avoid the formation of deformed flowers. If boron fertilizer is sprayed, spray 500-1000 times with water, once every 10 days. When the flowers are held or the fruit is seated, the calcium fertilizer should be sprayed once at a time. It is best to choose chelated calcium or calcium lignin and spray 1000-2000 times with water. You can also apply boron calcium fertilizer in advance. When the first flower of each ear is opened reasonably, 3 to 4 flowers will grow together after the first flower, and 2 to 3 days after the first flower of each ear, 4 to 5 flowers will appear in the back. It is also important at this time. You should master the flowers before they bloom. It should be noted that the concentration of dot anthers should decrease with the increase of temperature to avoid the formation of deformed fruits due to the excessive concentration of dot anthers. Control the temperature of the flowering period. The temperature in the daytime is about 28 ℃, not more than 34 ℃, and the night temperature is not more than 20 ℃. When the temperature is too high, it is recommended to use a shading net or a cooling agent to cool down. Before and after noon, it can be used with micro-spraying equipment to cool the water, and it also relieves the humidity in the shed. Spraying the flower-promoting fertilizer seaweed or amino acid foliar fertilizer can improve the quality of the flower, ensure fruit development, and enhance the fruit's resistance to stress. For example, alginic acid foliar fertilizer, spray 500 to 1000 times with water, continuous spraying 2 ~3 times to promote flowering and fruit setting. Reasonably retain the fruit. When the young fruit sits, select the fruit of the same size, similar fruit shape and no pests and diseases, and then remove the rest of the fruit. For example, large fruit type tomato leaves about 3 per ear, medium and small fruit type can leave 4 to 5, and deformed fruit should be removed in time.
