Eggplant summer fertilization method

It is necessary to ditch deep and apply some vegetable farmers to apply fertilizers when they are chasing fertilizers. In fact, this fertilization method is unscientific under high temperature conditions. Because, under high temperature conditions, nitrogen fertilizers, especially ammonium bicarbonate, are easily decomposed and volatilized, and the ammonia produced by decomposition not only reduces the fertilizer efficiency, but also easily causes eggplant ammonia poisoning. Therefore, in view of the characteristics of nitrogen fertilizer, deep application should be carried out. The depth of the ditch is 5 to 8 cm. After the application, the soil should be buried and watered.

The amount of scientific eggplant needs a large amount of nitrogen fertilizer during the fruit-bearing period. However, under high temperature conditions, the conversion rate of urea after application to the soil is relatively fast. After the plant meets the needs, the excess will be lost, especially the sandy soil. The rate of fertilizer loss will be higher. Therefore, it is necessary to use a fertilization method that eats less meals, and generally applies 15 to 20 kg of urea per mu.

Although it is necessary to properly mix eggplant with nitrogen fertilizer, phosphorus and potassium fertilizers are also essential. When topdressing, you can't only apply nitrogen fertilizer every time. In the fruit-bearing period, it should be combined with phosphorus and potassium fertilizer for 2 to 3 times, which can improve eggplant yield, improve quality and prolong the harvesting period. Generally , 20 kg of phosphate fertilizer and 10 kg of potassium fertilizer are applied every time .
