When eggplant enters high temperatures in summer, the amount of fertiliser increases with the increase in reproductive growth. A reasonable supply of fertilizer is required to ensure normal growth.

Dosage Scientific eggplant needs a large amount of nitrogen fertilizer during the full fruit period, but in high temperature weather conditions, fertilization methods should be used with “a small number of times”. Under high temperature conditions, the conversion rate of urea after applying to the soil is relatively fast. After the plants meet their needs, the excess will be lost. Normally, fertilizer is applied once every 7 days, and 10 to 15 kg of urea is applied per mu, or 10 to 15 kg of dragon light is really good. Excessive application rate, in addition to causing loss of nutrients, can also cause ammonia damage to the leaves and leaves of eggplant.

The method must be scientific and many farmers have the habit of flushing with water, but this method should not be used under 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 topdressing fertilizers such as urea, ammonium bicarbonate, ammonium sulfate, etc., it is necessary to adopt a ditch or cave method. The depth is not less than 5 cm, so as to reduce the volatilization of the active ingredients of the fertilizer, and timely watering after top dressing.

To formulate fertilization Although eggplant requires a large amount of nitrogen fertilizer, phosphorus and potassium fertilizers are indispensable, and nitrogen fertilizer cannot be topdressed each time during topdressing. In the fruit period, it is necessary to use phosphorus and potassium fertilizers 2~3 times. It is best to use ternary compound fertilizer. You can also use real roots of dragon light and real nail polish to dilute 300 to 500 times with water to meet the growth of eggplant. The need for results can also play a role in improving the quality of solanaceous fruit.
