How to get fat after summer eggplant?

How to get fat after summer eggplant? Please introduce summer eggplant can refer to the following methods for topdressing: 1, appropriate amount. Eggplant needs the largest amount of nitrogen fertilizer, but in the hot season, it is necessary to eat less and eat more. Each application of urea per 667m2 should generally be controlled within 30kg. Because in the high temperature season, the transformation rate of urea is relatively fast after urea is applied to the soil, and the excess part will be lost after the plant meets the needs. Especially in sandy soil, the proportion of loss will be greater. It is appropriate for ammonium bicarbonate to apply less than 40kg per 667m2 each time. Excessive application rate will not only cause nutrient loss, but also cause ammonia damage to eggplant leaves and fruits. 2. Appropriate law. It has become a habit for vegetable farmers to apply chemical fertilizer with water, but this method should not be used in summer high temperature season. Because of the high temperature, the fertilizer efficiency will be reduced after a large amount of ammonia volatilization during the application of chemical fertilizer. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. The effect of ditch application or hole application is the best, and the thickness of buried soil should not be less than 5cm after topdressing, so as to reduce the volatilization of effective components of chemical fertilizer. 3. Reasonable collocation. Although eggplant needs the most nitrogen fertilizer, phosphorus and potassium fertilizer is also indispensable. When following fertilizer, you can't apply nitrogen fertilizer every time. In the full fruit period, it is best to topdressing two times of ternary compound fertilizer, the total amount of two times per mu should not be less than 40kg, in order to meet the needs of eggplant growth and fruit.
