Method 1: Topping the eggplant:
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.
Method 2: Promote weak and control of eggplant plants:
Generally, eggplant plants grow weakly and lack of nutrients, which will intensify the falling and falling of fruit. However, if the growth is too strong, it will cause the relative lack of nutrition and cause the fruit 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 stage. It is best to use 500-600 kilograms of cooked and diluted manure in the middle of flowering, 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.
Method 3, using 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.
Method 4, carry out artificial pollination:
The eggplant flower is open at about 6 o'clock in the morning. After 7 o'clock, the anther begins to crack, so the appropriate pollination time is 8 hours after each day. Hybrid pollination should be in the afternoon before the opening of the mother flower, choose the corolla to extend the flower buds l/2, pale purple, the buds that have not yet been opened to go to the male, the male must be thorough, the second day after the male to the male is open Powder (the highest pollination rate of pollen on the day), the pollen is applied to the stigma of the female parent.
