â—It has become a habit for vegetable farmers to apply chemical fertilizer and flushing with water, but this method is not suitable for summer high temperature season. Because of the high temperature, when a large amount of ammonia volatilizes when applying chemical fertilizers, fertilizer efficiency will be reduced. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. The effect of ditching or hole application is the best, and the thickness of the buried soil after top dressing should be no less than 5 cm to reduce the volatilization of the effective components of the fertilizer. â—Reasonable combination of eggplant. Although the nitrogen fertilizer requirement is the best, phosphorus and potassium fertilizer are also indispensable. You can't apply nitrogen fertilizer every time when topdressing. In the full fruit period, topdressing two ternary compound fertilizers should be applied twice, and the total amount should not be less than 40 kg per mu to meet the needs of eggplant growth and fruit.

How to topdress the eggplant in summer?
â—A proper amount of eggplant requires the most amount of nitrogen fertilizer, but in the hot season, eat less and more meals. Urea per mu should be controlled within 30 kg each time. Because of the high temperature season, the conversion rate of urea is relatively fast after it is applied to the soil. After meeting the needs of the plants, the excess part will be lost, especially in sandy soil, the proportion of loss is greater. The application rate of ammonium bicarbonate per acre should not exceed 40 kg. Excessive application rate will cause nutrient loss and ammonia damage to eggplant leaves and fruits.
