Fertilization
It is customary for vegetable growers to use chemical fertilizers, but it is not a good practice to use this method during summer hot seasons. Because of the high temperature, when ammonia is volatilized, the effect will be reduced when the ammonia is volatilized. Especially ammonium bicarbonate is more likely to cause eggplant ammonia poisoning. The use of trenching or digging a hole to bury the best. The thickness of the buried soil after dressing should be not less than 5 cm to reduce the volatilization of the active ingredients of the fertilizer.
Attention to the amount of application
Eggplant requires the most amount of nitrogen, but in the hot season, it is necessary to eat less. Urea application per acre should generally be controlled within 30 kilograms. Because of the high temperature season, the rate of transformation of urea into the soil is relatively fast. After the plants meet their needs, the excess will be lost. Especially sandy soil, the proportion of loss will be greater. It is more appropriate for ammonium bicarbonate to use no more than 40 kg per acre. If the application amount is too large, besides causing loss of nutrients, it will also cause ammonia damage to leaves and fruits of eggplant.
Reasonable collocation
Although eggplants require the largest amount of nitrogen, phosphorus and potash are indispensable. When top dressing, only nitrogen fertilizers cannot be topped each time. In the full fruit period, it is best to apply two compound fertilizers at a rate of not less than 40 kilograms per acre to meet the needs of eggplant growth and results.
