It has become a habit for vegetable farmers to apply chemical fertilizers in ditching and fertilization, but it is not suitable to use this method in hot seasons, because the temperature is higher, and the effect of a large amount of ammonia volatilization will be reduced when the fertilizer is applied. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplants. The effect of using trenching or digging to bury is the best. 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.
Pay attention to the amount of nitrogen fertilizer required for eggplant, but in the hot season, "eat less and more meals". Urea application 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 the plants meet the needs, the excess part will be lost. Especially in sandy soil, the proportion of loss will be greater. The application rate of ammonium bicarbonate per mu should not exceed 40 kg. Excessive application rate will cause damage to eggplant leaves and fruits in addition to the loss of nutrients.
Reasonable collocation of eggplant. Although the nitrogen fertilizer requirement is the best, phosphorus and potassium fertilizers are also indispensable. It is not necessary to apply only nitrogen fertilizer every time when topdressing.
