Matters needing attention in topdressing eggplant in midsummer

Eggplant grows faster in a high temperature environment, but it also needs sufficient fertilizer to supply its growth, so topdressing of eggplant in midsummer is very important, but fertilization in midsummer should also pay attention to a few points. Let's take a look at the matters needing attention for eggplant topdressing in midsummer.

1. Ditching and fertilization

It has become a habit for farmers to apply chemical fertilizer with water, but it is not suitable to use this method in summer high temperature season, because the temperature is higher, when applying chemical fertilizer, a large amount of ammonia volatilization will reduce the fertilizer efficiency. In particular, ammonium bicarbonate fertilizer is more likely to cause eggplant nitrogen poisoning, so the effect of ditching or burying is the best. After topdressing, the thickness of the buried soil should not be less than 5 cm to reduce the volatilization of the effective components of chemical fertilizer.

2. Pay attention to the dosage

Eggplant has a great demand for nitrogen fertilizer, but in the high temperature season, we must follow the principle of "eat less and eat more". Each application of urea per mu should be controlled within 30kg. Because in the high temperature season, the conversion speed of urea into the soil is relatively fast, after meeting the needs of the plant, the excess nutrients will be lost, resulting in waste, especially in sandy soil, the proportion of loss will be greater. The appropriate application amount of ammonium bicarbonate per mu is no more than 40 kg per mu. Excessive application will not only cause nutrient loss, but also cause ammonia damage to eggplant leaves and fruits.

3. Reasonable collocation

Although eggplant has a large demand for nitrogen fertilizer, it is also indispensable for phosphorus and potassium fertilizer. It is best to apply three-yuan compound fertilizer twice in the full fruit period, but not less than 40 kg per mu each time, in order to meet the growth and fruiting needs of eggplant and increase the yield.
