Eggplant grows vigorously, yields high, and the demand for fertilizers is also large, especially in the summer high temperature season, while picking, fertilizing, is the key to obtain high yield. However, pay attention to the following points when fertilizing: One, can not be partial nitrogen fertilizer, top dressing with other fertilizers, especially potassium. If partial application of nitrogen fertilizer, neglect the application of potash fertilizer, it will result in falling, fruiting, lodging, reduce the resistance of the plant, thus affecting the yield and quality. Followed by the use of trace elements boron is also a key, reasonable application of boric acid or borax, can make eggplant bright color, improve quality. Second, the top dressing should be eaten less frequently, each time the amount should not be too large. 1, topdressing urea in 20 kg per mu. If the amount is too much, the conversion rate of urea after applying it into the soil in the high temperature season is relatively fast. After the plants meet the requirements, the surplus part will cause the loss. Not achieve the desired effect. Generally eggplant dressing is applied once every 10-15 days. 2. Potassium dihydrogen phosphate is generally used in the production of potassium dihydrogen phosphate. It is sprayed once every 7-10 days with a concentration of 0.2-0.3%. The concentration of boric acid or borax is 0.05%-0.25%. Spraying is done once every 10-15 days. The amount of spraying solution is 50-70 kilograms. When spraying, avoid sunlight at noon. Spraying should not be applied on rainy days. Do not mix with alkaline pesticides. Third, pay attention to fertilization methods, at present, most farmers are accustomed to chasing fertilizer habits with water. However, this method should not be used in summer hot season because of the high temperature. When the chemical fertilizer is used, a large amount of ammonia volatilizes will reduce the fertilizer efficiency, especially ammonium bicarbonate, which is more likely to cause eggplant ammonia poisoning. Therefore, it is best to apply acupuncture points.
