Eggplant pay attention to three points in the summer

Ditching and fertilizing

It is a habit for vegetable farmers to apply fertilizers with water, but it is not suitable for this season in high temperature seasons. Because of the higher temperature, when ammonia fertilizer is applied, a large amount of ammonia vapor will reduce the effect. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. It is best to use ditching or digging. 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 dosage

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 speed of urea is relatively fast after it is applied to the soil. After the plant meets the needs, the excess will be lost. Especially in sandy soils, the proportion of loss will be greater. It is suitable to apply ammonium bicarbonate at a rate of not more than 40 kg per acre. If the application rate is too large, it will cause loss of nutrients, and it will cause ammonia damage to eggplant leaves and fruits.

Reasonable match

Although eggplant requires the largest amount of nitrogen fertilizer, phosphorus and potassium fertilizers are 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, to meet the needs of eggplant growth and results.
