It is necessary to supply as many as possible assimilation nutrients so that the fruits are adequately nutritious and reduce the occurrence of empty fruit. Seedlings that are easily detached from flower buds generally have poor root development, a small number of roots, and weak assimilation. The use of growth hormone promotes fruit setting and is prone to empty fruit. If you reduce the number of fruit set, the occurrence of empty fruit will be reduced. The plants had good flower buds, and they were injured when they were transplanted to form the aging seedlings. The development of the root system in the field was not good, and the leaves were susceptible to aging and the assimilation was weakened. According to the growth potential of the plants, the fruits are set in proportion, and the fruits are slowly expanded to provide sufficient nutrients and reduce the occurrence of empty fruit. When the leaf area is small, the first inflorescence is heavily fruited, and the fruit at the bottom of the plant needs the assimilation nutrients supplied by the whole plant, and there are fewer empty fruits. However, if there is less assimilation of nutrients in the upper fruits, empty fruit will be formed. When the assimilation of nutrients is insufficient, the fruit cannot expand well, and when there is little nutrients, it cannot be established. In the same inflorescence, when the flowering time from the first flower to the fifth or sixth flower is not concentrated, it will cause competition for assimilation of nutrients between the fruits, and the fruit of late flowering will form empty fruit, so in the same inflorescence, The 3-4 flowers that are simultaneously flowering are treated together with growth stimulants. When the soil has more nitrogen, more water, and higher night temperatures, flowering dates are not easy. On the contrary, when the soil was slightly dry and the night temperature was low, flowering was more orderly. At night, when the temperature is high, especially when applying nitrogen fertilizer and pouring water, most of the assimilation nutrients are distributed to the plants, but the fruit is distributed very little. In this case, it is necessary to carry out topping. According to different environmental conditions, in order to increase the leaf area, a part of the fruit can be removed to increase the number of leaves so that the assimilation of nutrients can be increased and the appearance of empty fruit can be prevented. Less use of plant growth regulators to promote fruit set, mainly artificial pollination, supplemented with growth regulators. In the case of ensuring a certain number of fruit set, the number of use of the growth regulator is reduced, the amount of the growth regulator entering the plant is reduced, and it is preferable that the unripe flowers are not treated with a high concentration of the growth regulator.
