Key Technical Points for Pollution-Free, High-Quality Eggplant Management

During the growth of eggplant, careful and scientific field management is essential to delay plant decline, ensure continuous flowering and fruiting, and increase yield.

The general fruiting pattern of eggplant is that fruit set increases as the plant branches, basically setting one fruit per branch. In planting management, this characteristic should be fully utilized by promptly pinching the growing tips after transplanting to promote rapid branching, increase the number of fruiting sites, and raise the fruit-setting rate.

Weak eggplant plant growth and insufficient nutrition will worsen flower and fruit drop; however, excessive vegetative growth will also cause relatively insufficient nutrition and lead to flower and fruit drop. Eggplant fruit set increases as the plant branches. After transplanting, the growing tips should be pinched promptly, and Cuihuawang No. 3 should be sprayed to inhibit excessive growth of the main shoot, promote rapid branching of the plant, increase fruiting sites, and raise the fruit-setting rate. In addition, fertilizer and water should be applied promptly before flowering. Before flowering, at the young fruit stage, and at the fruit swelling stage, spray Caiguo Zhuangdiling to increase nutrient transport, inhibit excessive shoot growth, promote flowering, strengthen flowers, and thicken the fruit stalk, improving the fruit's swelling vigor. At the same time, spray Xingao Zhimo to form a protective film and prevent the spread of airborne viruses.

When strengthening fertilizer and water management for weak seedlings, organic fertilizer and quick-acting phosphorus should be the main focus in the early stage, and quick-acting nitrogen fertilizer should be used in the middle and late stages. It is best to apply 500-600 kg of decomposed dilute manure per mu at flowering, or 20-30 kg of cake fertilizer plus 15-20 kg of superphosphate. After entering the full fruiting stage, topdressing should shift to quick-acting nitrogen fertilizer as the main type (apply 10-15 kg of urea per mu each time), with 3-5 topdressings during the fruiting period. At the same time, use Genshitong and micro-fertilizers for root irrigation, which can induce the plant's absorption, digestion, and release of nitrogen, phosphorus, potassium, and various trace elements in the soil, enhance the positive energy of eggplant development, and optimize eggplant quality.
