Eggplant summer topdressing has three taboos

Avoid excessive application of large amounts of eggplant. The demand for nitrogen fertilizer in the fruit-bearing period is very large, but in high-temperature weather conditions, the application method of “small number of times” should be adopted, and the amount of one-time application should not be too large. Generally, the topdressing is applied once every 7 days, and 10-15 kg of urea is applied per acre.

Avoid using water with a lot of vegetable farmers to apply fertilizer with the habit of water, but in the summer hot weather conditions should not use this method. Because of the higher temperature, 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, when applying fertilizers such as urea and ammonium bicarbonate, it is necessary to take a ditch or a hole.

Avoid applying nitrogen fertilizer alone. When topdressing, you can't only apply nitrogen fertilizer every time. In the fruiting period, it is necessary to apply phosphorus and potassium fertilizer 2 to 3 times, preferably using ternary compound fertilizer to meet the needs of eggplant growth and results, and also to improve the quality of the eggplant fruit.
