Topping. The general rule of fruit set in eggplants increases with the tillering of the plants, basically one fruit per branch. In planting management, this feature should be fully utilized, and topping should be carried out in time after planting to promote rapid branching, increase the result area, and increase the fruit setting rate.
Promote weak control. The growth of eggplant plants is weak, and the lack of nutrition will aggravate the falling flowers and fruits. However, if the growth is too strong, it will cause the relative lack of nutrition and cause the flowers to fall. Therefore, maintaining normal growth is the basic requirement for promoting eggplant into flowers and fruit. Therefore, plants with weak growth should be enhanced by applying fertilizer water; if the growth is too high, it is necessary to properly control the fertilizer and water to promote normal growth, in order to improve the fruit setting rate. The specific method is: when strengthening the management of fertilizer and water for weak seedlings, the organic fertilizer and available phosphorus should be mainly used in the early stage, and the quick-acting nitrogen fertilizer should be used in the middle and late period. It is best to use 500-600 kilograms of cooked and diluted manure during the flowering period, or cake fertilizer. 20-30 kg, add 15-20 kg of superphosphate. After entering the fruiting period, the topdressing should be turned to quick-acting nitrogen fertilizer (10-15 kg of urea per acre), and 3-5 times in the result period.
Hormone treatment. At the flowering stage, 20ppm anti-falling flower spray, or 30-40ppm 2,4-D silk flower can prevent falling flowers and fruit, thereby increasing the fruit setting rate.
