How to manage eggplant cultivation? Complete eggplant cultivation tips

We need to manage eggplants after planting them, so here are some eggplant management techniques:

1. Eggplant topdressing technology

May is the peak season for eggplants, and the demand for fertilizer and water is very high. Eggplants like water, so pay attention to keeping the soil moist. When there is a shortage of water, you can irrigate and ditch irrigation. 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. When irrigating, fill a ditch with water, and then evenly spread the above fertilizers in the ditch to melt. The amount per mu can be 15-30 kg, 10 kg, and 10 kg, respectively. If the vegetable field is not short of water, you can dig a nest between every four eggplants and put fully decomposed farmyard manure in the nest. Note: After topdressing, the ventilation should be increased to prevent fertilizer damage and disease.

2. Late-stage eggplant management: picking old leaves

In addition to removing the axillary buds of eggplant, keep one or two leaves at the bottom (largest) of the plant, and remove all other old leaves at the bottom.

3. Dig Deep Trench

Using the soil from the trench to raise the bed surface can prevent flooding, increase soil permeability and reduce soil temperature.

4. Disease prevention

After May, eggplant diseases and pests are mainly gray/wool blight and powdery mildew. Gray blight is manifested by light brown to brown spots on mature fruits, which are slightly sunken. When the disease worsens, the whole fruit turns dark brown. If the humidity increases, a grayish-white frosty mold layer will form on the fruit surface, which will gradually soften and rot, emitting a foul odor. Sometimes, the disease occurs during the transportation of eggplants and on stalls in stores. High temperature and high humidity are most conducive to the growth and development of wool blight bacteria, and of course, it is also conducive to the infection of other pathogens. Therefore, in the hot and rainy summer, a large number of eggplants can be seen rotting and quickly growing long and dense white hairs. A large number of eggplant fruits that are about to mature will soon become rotten eggplants after being infected by wool blight bacteria.

Prevention and treatment methods:

When the disease first occurs, the central diseased plants should be immediately removed and destroyed and sprayed for prevention and control. Starting from the rainy season, spray 1:1:200 times Bordeaux mixture every 7 days for protection, which has a very good effect. Once the disease occurs, it is necessary to apply the medicine immediately. The medicines include 75% thiophanate-methyl 500-600 times solution, 50% methyl thiophanate wettable powder 800 times solution, 40% ethyl phosphine wettable powder 200 times solution, 64% anti-virus alum 500 times solution, etc. Generally, spray once every 7-10 days, and spray 3-4 times in a row. The above-mentioned medicines are mixed with Tianda-2116 melon and solanum special type for better effect. In order to prevent the formation of drug resistance, different types of drugs should be used each time.
