1, topping. Generally, the rule of fruit set of the eggplant is increased with the tillering of the plant, basically one fruit per tiller. The most common ones are the ones on the door, two on the eggplant, four on the four-male eggplant, and eight on the eight-facet eggplant. Therefore, in the management of planting, this feature should be fully utilized, and the topping should be carried out promptly after planting so as to promote its rapid branching, increase the result area and increase the fruit setting rate. 2, promote weak control. Eggplant plant growth is weak, lack of nutrition, will exacerbate flowering and fruit loss; but excessive growth, it will cause the relative lack of nutrition caused by falling flowers. Therefore, maintaining normal (not prosperous or weak) growth is the basic requirement for the promotion of eggplant flowering and fruit setting. Therefore, for weakly growing plants, water must be added to make them grow stronger; over-promoting water should be properly controlled to promote normal growth and increase fruit setting rate. The specific approach is: to strengthen the management of weak seedlings fertilizer, the early stage should be based on organic fertilizer and available phosphorus, in the middle and late can be changed to available nitrogen fertilizer, it is best when the door eggplant flowering, Mu chase maturity dilute 500 to 600 kg , Or cake fat 20 ~ 30 kg, adding 15 ~ 20 kg Pu pass calcium phosphate. After entering the full fruit period, the topdressing should be turned to quick-acting nitrogen fertilizer (10 ~ 15 kg of urea per mu) and chase 3 to 5 times in the result period. At the same time, we must pay attention to watering in combination with topdressing. For over-emergence seedlings, the stems of the plants can be pinched at the flowering stage to promote the accumulation of photosynthetic products and promote fruit setting. The roots can also be damaged by cultivating the roots to reduce the ability of the plants to absorb nutrients and water, thus reducing the growth and promoting the results. 3, hormone treatment. Flowering with 20ppm anti-droplet spray, or with 30 ~ 40ppm 2,4-d flower, can be achieved to prevent flowering and fruit drop, in order to improve the fruit setting rate. 4, artificial pollination. Artificial pollination should be carried out in the protected area. Pollination time is best when it is 8 to 10 in the morning.
