During the cultivation of eggplant, sometimes the fruit setting rate is extremely low. In general, the main reasons are: poor environmental conditions, such as insufficient light, continuous low temperature, excessive humidity and some diseases and insect pests; the density is too large. Small ventilation, malnutrition, etc., may cause eggplants not to set fruit. In addition to controlling suitable environmental conditions, cultivation should also be carried out.

1, topping. Generally, the rule of fruit set of the eggplant is increased with the tillering of the plant, basically one fruit per tiller. In the management of planting, this feature should be fully utilized and timely picking should be carried out 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 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 method is: to strengthen the weak seedlings to enhance fertilizer and water management, the early stage should be organic fertilizers and available phosphorus, in the middle and late to use a fast-acting nitrogen fertilizer, it is best when in flowering, Mu chase maturity dilute fecal 500-600 kg, or cake fat 20-30 kg, add 15-20 kg of superphosphate. After entering the full fruit period, topdressing should be shifted to fast-acting nitrogen fertilizers (10-15 kg of urea per mu), chasing 3-5 times in the result period.

3, hormone treatment. Flowering with 20ppm anti-dropping agent, or with 30-40ppm 2,4-D flower, can prevent flowering and fruit drop, thereby increasing the fruit setting rate.

4, artificial pollination. Artificial pollination time is best at 8-10 in the morning.
