During the growth of eggplant, it is necessary to do meticulous and scientific field management in order to delay plant decline, ensure continuous flowering results, and increase yield. The commonly used stimulation measures in production practice are:
First, take heart
Generally, the rules of fruit set in eggplant increase with the tillers of the plant. In the management of planting, this characteristic 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.
Second, timely recovery of fruit fertilizer
When each layer of fruit begins to swell, about one time every 10 days or so, it recovers a total of 5 to 6 times of fat. Fertilizer and dilute urine are best used interchangeably.
Third, 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. For weakly growing plants, water must be added to make them grow stronger; overgrowth should be properly controlled with fertilizers and water to promote normal growth so as to increase fruit setting rate.
The specific approach is: to strengthen the management of weak seedlings fertilizer, the early stage should be mainly organic fertilizer and available phosphorus, in the middle and later to use a fast-acting nitrogen fertilizer, it is best when the flowering Mu Mu cooked defecate 500 to 600 kg or cake fertilizer 20 ~ 30 kg, with 15-20 kg of superphosphate. 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.
Fourth, hormone treatment
Flowering with 20ppm anti-droplet spray, or with 30 ~ 40ppm 2,4-D flower, can prevent flowering and fruit drop, thereby increasing fruit set rate.
V. timely spraying fertilizer
From the beginning of the outcome period, it is possible to spray 0.2%-0.3% urea, 0.2%-0.3% potassium dihydrogen phosphate, 0.1%-0.2% magnesium sulfate and other fertilizers according to the growing trend. Usually 7 to 10 days, spray once, and even spray 2 ~ 3 times.
