When topdressing eggplant in summer, note the following points:
Avoid applying too large a single dose
Eggplant has a very high demand for nitrogen fertilizer during the full fruiting period, but under high-temperature weather conditions, the "small amounts, multiple times" fertilization method should be used, and a single too-large dose must be avoided. Generally, topdress once about every 7 days, applying 10-15 kg of urea per mu each time.
Avoid applying by washing with water
Many vegetable growers have the habit of applying chemical fertilizer by washing it in with water, but this method is not suitable under high-temperature summer weather conditions. Because the temperature is relatively high, nitrogen fertilizers, especially ammonium bicarbonate, decompose and volatilize very easily; the ammonia gas produced by decomposition not only reduces fertilizer efficiency but also easily causes ammonia poisoning in eggplant. Therefore, when topdressing fertilizers such as urea and ammonium bicarbonate, trench application or hole application must be used.
Avoid applying nitrogen fertilizer alone
When topdressing, do not apply only nitrogen chemical fertilizer every time. During the full fruiting period, apply phosphorus and potassium fertilizers together 2-3 times, preferably with a ternary compound fertilizer, to meet the needs of eggplant growth and fruiting, and it can also help improve the quality of the eggplant fruit.
