How to fertilize eggplant in summer? Please introduce to the guide that summer eggplant can be topdressing like this (for reference): ditch fertilization. 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 effect will be reduced after a large amount of ammonia volatilization in the application of chemical fertilizer. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. The effect of ditching application or burying hole application is the best. The thickness of buried soil should not be less than 5 cm after topdressing to reduce the volatilization of effective components of chemical fertilizer. Pay attention to the dosage. 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 mu should generally be controlled within 30 kg. Because in the high temperature season, the transformation speed is relatively fast after urea is applied into the soil, after the plant meets the needs, the excess part will cause loss. Especially in sandy soil, the proportion of loss will be greater. It is suitable to apply ammonium bicarbonate no more than 40 kg per mu each time. Excessive application will not only cause nutrient loss, but also cause ammonia damage to eggplant leaves and fruits. It's a reasonable match. Although eggplant needs the largest amount of nitrogen fertilizer, phosphorus and potassium fertilizer is also indispensable. When topdressing, you can't just apply nitrogen fertilizer every time. In the full fruit period, it is best to apply three-yuan compound fertilizer twice, each time not less than 40 kg per mu.
