What should we pay attention to when topdressing eggplant in summer? Please guide eggplant topdressing in summer to pay attention to the following points: avoid excessive one-time application of eggplant in the full fruit period of a great demand for nitrogen fertilizer, but in high temperature weather conditions, should use "a small number of times" fertilization method, do not apply too much at one time. Generally about 7 days topdressing once, each time the application of urea 10-15 kg per mu. Many vegetable farmers have the habit of applying chemical fertilizer with water, but this method is not suitable under the condition of high temperature in summer. Because of the high temperature, nitrogen fertilizers, especially ammonium bicarbonate, are very easy to decompose and volatilize. The ammonia produced by decomposition not only reduces the fertilizer efficiency, but also easily causes eggplant ammonia poisoning. Therefore, ditch or hole application must be adopted when topdressing urea, ammonium bicarbonate and other fertilizers. Do not apply nitrogen fertilizer alone. You can't only apply nitrogen fertilizer every time. In the full fruit period, it is necessary to apply phosphorus and potassium fertilizer for 3 times, and it is best to use ternary compound fertilizer to meet the needs of eggplant growth and fruiting, and can also play a role in improving eggplant fruit quality.
