It is a habit to apply fertilizers with the ditch and fertilize the vegetable farmers. It is not a good practice to use the water in the summer season. Because of the higher temperature, when a chemical fertilizer is applied, a large amount of ammonia gas volatilizes to reduce the effect. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. It is best to use ditching or burrowing. The thickness of the buried soil after top dressing should be no less than 5 cm to reduce the volatilization of the active ingredients of the fertilizer.
Note that the amount of eggplant requires the largest amount of nitrogen, but in the hot season, it is necessary to "eat less meals." Urea should be controlled within 30 kg per mu. Because of the high temperature season, the conversion rate of urea after it is applied to the soil is relatively fast. After the plant meets the needs, the excess will be lost. Especially in sandy soils, the proportion of loss will be greater. It is more suitable to apply ammonium bicarbonate at a rate of not more than 40 kg per acre. Excessive application rate will cause ammonia loss in eggplant leaves and fruits, in addition to nutrient loss.
Reasonable matching of eggplant Although the nitrogen fertilizer needs the largest amount, but the phosphorus and potassium fertilizer is also indispensable. In the top dressing, it is not possible to apply nitrogen fertilizer every time. In the fruiting period, it is best to apply two ternary compound fertilizers, each time no less than 40 kg per mu.
