Avoid excessive use of eggplant in a large amount of a large amount of nitrogen fertilizer in the fruit period, but in high-temperature conditions, should be used "a small number of times" fertilization method, avoid excessive application of a single dose. Usually about 7 days topdressing 1 times, each urea 10 ~ 15 kg.

Avoid using a lot of vegetable farmers to follow up the application of chemical fertilizer with the water flushing habits, but in summer hot weather conditions should not adopt this method. Because of the high temperature, nitrogen-based fertilizers, especially ammonium bicarbonate, are easily decomposed and volatilized. The ammonia produced by the decomposition not only reduces the fertilizer efficiency, but also easily causes eggplant ammonia poisoning. Therefore, when applying topdressing fertilizers such as urea and ammonium bicarbonate, it is necessary to adopt a ditch or a hole.

Avoid applying single nitrogen fertilizer to topdressing nitrogen fertilizer. In the fruit period, it is necessary to use phosphorus and potassium fertilizers 2 to 3 times. It is best to use ternary compound fertilizers to meet the needs of eggplant growth and results, and also to increase the quality of solanaceous fruit.
