How to top dress eggplant in high temperature season

Eat eggplant in summer , there is also a lot of iron inside, good for the body! So in summer, I want to have a good harvest, reasonable topdressing is particularly important, unreasonable topdressing will often lead to a large number of production cuts, so the eggplant should be properly topdressed in the hot season, grasp the following Three points guarantee you a good harvest this summer.

1. Master the amount of fertilization <br> Eggplant requires the largest amount of nitrogen fertilizer, but in the hot season, the urea should be controlled within 30 kg per mu. Because of the high temperature season, the conversion rate of urea after applying the soil is faster. When the need is met, the excess will be lost. Especially in sandy soils, the proportion of loss will be greater. 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 eggplant leaves and fruits.

2, using ditch fertilization: vegetable farmers to apply fertilizer, with water has become a habit, but in summer high temperature season should not use this method. Because of the higher temperature, a large amount of ammonia vapor will be reduced after the chemical fertilizer is applied. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. It is best to use ditching or burrowing. 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 mix: Although the eggplant needs the largest amount of nitrogen fertilizer, but phosphorus and potassium fertilizer is also indispensable, in the top dressing can not only 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.
