Picking the eggplant, the general rule of fruit set-up is to increase with the birth of the plant, basically one fruit for each 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.
Weak control of strong eggplant plant growth is weak, lack of nutrition, will exacerbate flowering and fruit drop; but excessive growth, it will cause the relative lack of nutrition caused by falling flowers. Therefore, maintaining the normal growth is the basic requirement to promote 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 organic fertilizer and available phosphorus, the middle and late to use fast-acting nitrogen fertilizer, it is best when flowering, Mu chase maturity of 500-600 kg of loose manure, or cake fat 20-30 kg, add 15-20 kg of superphosphate. After entering the full fruit period, the topdressing should be turned to fast-acting nitrogen fertilizer (10-15 kg of urea per mu), chasing 3-5 times in the result period.
Hormone treatment flowering period with 20ppm anti-producing spray, or with 30-40ppm 2,4-D flower, can prevent flowering and fruit drop, thereby increasing the fruit setting rate.
