Eggplant itself does not require high levels of fertilizer, but summer temperatures are high, and improper fertilization can easily lead to fertilizer damage.
A bogey with water facilities. Many vegetable farmers have the habit of fertilizing chemical fertilizers with water, but they are not suitable for summer hot weather conditions. 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.
The second avoid bogey one-time fertilization is too large. The demand for nitrogen fertilizer in aubergine during the fruit-filling period is very large, but in high-temperature weather conditions, fertilization methods with “a small number of times†should be adopted, and the one-time application amount should not be too large. Usually about 7 days topdressing 1 times, each urea 10 ~ 15 kg.
Three bogey single nitrogen fertilizer. Only topdressing nitrogen fertilizers cannot be applied at the top dressing. 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.
