What should you pay attention to to fertilize eggplant in summer? It is necessary to pay attention to the following three points for topdressing eggplant in summer: ditch fertilization, vegetable farmers apply chemical fertilizer, it has become a habit to apply chemical fertilizer with water, but this method should not be used in summer high temperature season, because the temperature is higher, when flushing chemical fertilizer, a large amount of ammonia volatilization will reduce the effect. In particular, ammonium bicarbonate is more likely to cause ammonia poisoning in eggplant. The effect of ditching application or burying hole application is the best. The thickness of buried soil should not be less than 5 cm after topdressing to reduce the volatilization of effective components of chemical fertilizer. Note that the amount of eggplant needs the largest amount of nitrogen fertilizer, but in the high temperature season, it is necessary to "eat less and eat more". Each application of urea per mu should generally be controlled within 30 kg. Because in the high temperature season, the transformation speed is relatively fast after urea is applied into the soil, after the plant meets the needs, the excess part will cause loss. Especially in sandy soil, the proportion of loss will be greater. It is suitable to apply ammonium bicarbonate no more than 40 kg per mu each time. Excessive application will not only cause nutrient loss, but also cause ammonia damage to eggplant leaves and fruits. Although reasonable collocation of eggplant requires the greatest amount of nitrogen fertilizer, phosphorus and potash fertilizer is also indispensable. We can't only apply nitrogen fertilizer every time. In the full fruit period, it is best to apply three-yuan compound fertilizer twice, each time not less than 40 kg per mu, in order to meet the needs of eggplant growth and fruit.

What kind of fertilizers are used to top fertilizer in summer? Please introduce the summer field crops mainly topdressing nitrogen fertilizer, cash crops such as vegetables, tobacco, grapes, cotton, etc., in addition to nitrogen fertilizer but also potash fertilizer. For example, spring corn crops take the application of one-time urea base fertilizer as a reference. The other half of urea was used as topdressing at the end of July.

What do you need to pay attention to after topdressing crops? Please give us a wide variety of fertilizers for topdressing crops outside the roots, but some are suitable for foliar spraying and some are not suitable for foliar spraying. Such as urea, potassium dihydrogen phosphate, borax, ammonium molybdate, zinc sulfate and so on can be foliar spraying. Some chloride ions are volatile and difficult.
