Ditching and fertilizing Vegetable farmers are applying fertilizers to eggplants, and it has become a habit to use water, but this method should not be used in the summer high season. Because of the higher temperature, when the fertilizer is applied, a large amount of ammonia vapor will reduce the fertilizer efficiency, especially ammonium bicarbonate, which is more likely to cause ammonia poisoning in eggplant. The effect of ditching or digging a hole is better, and the thickness of the buried soil after top dressing should be no less than 5 cm.
Pay attention to the amount of eggplant requires a large amount of nitrogen fertilizer, but in the hot season, less duty should be applied. The urea applied per mu should be controlled within 30 kg each time. Because of the high temperature season, the conversion speed of urea after being applied to the soil is relatively fast. After meeting the needs of the plant, the excess will be lost. The application rate of ammonium bicarbonate per mu per mu is not more than 40 kg, and the application amount is too large, in addition to causing nutrient loss, it will also cause ammonia damage to the leaves and fruits of eggplant.
Reasonable matching Although the nitrogen fertilizer needs a large amount of nitrogen, the phosphorus and potassium fertilizers are also indispensable. It is best to apply two times of ternary compound fertilizer in the fruiting period, each time not less than 40 kg per mu. (Source: Henan Science and Technology News)
