The main management points for eggplant in summer are as follows for reference:
Eggplant likes water, so during the long drought with no rain in July, water must be supplemented to keep the soil moist. When irrigating, dissolve the fertilizers ammonium bicarbonate, monoammonium phosphate and potassium sulfate in water, with concentrations of about 0.3%, 0.15% and 0.2% respectively. For furrow irrigation, after filling a furrow with a large amount of water, evenly sprinkle the above fertilizers into the furrow to dissolve, with amounts per mu of 15-30 kg, 10 kg and 10 kg respectively. If there is no water shortage, dig a hole in the middle of every four eggplant plants and put fully decomposed farmyard manure into the hole. Note that topdressing should be determined according to plant growth and daily yield, and fertilizer damage must be strictly prevented.
Eggplant is prone to powdery mildew in summer, which requires special attention. When the disease occurs, spots of white powdery mildew appear on the leaf surface, and the mildew spots gradually enlarge and deepen in color. In severe cases, the entire leaf is covered with white powder. At the same time, mildew spots also appear on the back of the leaf, petiole, fruit stalk and calyx. The disease occurs easily at temperatures of 25°C-28°C and humidity of 50%-80%, and decreases when humidity reaches 100%. In the Sichuan region, the disease is mainly severe during high temperature and drought, and occurs less during rainy periods. At the initial stage, special powdery mildew agents should be sprayed, such as: triadimefon (Fenxiuning), Fuxing, sulfur-multi suspension concentrate, myclobutanil, Cuibei and other agents. Because eggplant leaves have many epidermal hairs, to increase the adhesion and spreading of the agent, 0.1%-0.2% laundry powder or 300-fold dilution of 27% high-fat film emulsion can be added when spraying; the mist droplets should be fine, the amount of water used should be sufficient, and spraying should be even.
