As the saying goes: "There is no income in the water, and more income is in the fertilizer." Eggplant wants to eat high first, let him eat well, how to make eggplant eat well in summer? Let’s listen to it:
1, the right amount.
Eggplant requires the largest amount of nitrogen, but in the hot season, it is necessary to eat less. Urea should be controlled within 30 kg per mu. Because of the high temperature season, the conversion rate of urea into the soil is relatively fast. After the plant meets the needs, the excess will be lost. Especially in sandy soil, the proportion of loss will be greater. The application rate of ammonium bicarbonate 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 eggplant leaves and fruits.
2. Appropriate law.
It is a habit for vegetable farmers to apply fertilizers, and it is 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. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. It is best to use ditching or acupoint application. 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.
3. Reasonable matching.
Although the eggplant needs the largest amount of nitrogen fertilizer, the phosphorus and potassium fertilizer is also indispensable. When following the fertilizer, it is not possible to apply nitrogen fertilizer every time. In the fruiting period, it is best to apply 2 times of ternary compound fertilizer, the total of 2 times per mu should be no less than 40 kg to meet the needs of eggplant growth and results.
