Key points of cultivation and Management of eggplant in May

1. Topdressing technology

May is the period of high yield of eggplant, and there is a great demand for fertilizer and water. Eggplant likes water, so you should always keep enough water in the soil in May. Irrigation and furrow irrigation can be carried out when there is a shortage of water. During watering, fertilizers ammonia bicarbonate, monoammonium phosphate and potassium sulfate are dissolved in water with concentrations of about 0.3%, 0.15% and 0.2%, respectively. After filling a ditch with heavy water during furrow irrigation, the above fertilizers are scattered evenly in the ditch to melt, and the dosage per mu can be 15-30 kg, 10 kg and 10 kg respectively. If there is no shortage of water, you can dig a nest among every four eggplants and put fully mature farm manure in the nest. Note that after topdressing, ventilation should be increased to prevent fertilizer damage and diseases.

Second, the late management to pick the old leaves: the eggplant should also remove the lower old leaves in addition to the axillary buds. One or two leaves are reserved under the lowest (largest) eggplant, and the rest should be removed.

Deep trenching: raising the surface of the box with the trenched soil can prevent flooding, increase soil permeability and reduce soil temperature.

Third, eggplant diseases and insect pests to May, eggplant disease is mainly gray / cotton blight, powdery mildew. Grey / cotton blight: light brown to brown spots appear on mature fruits with slight depressions. When the disease aggravates, the whole fruit is dark brown, and if the humidity increases, the fruit surface produces a gray-white frost-like mildew layer, which gradually softens and rotts and gives off a stench. Sometimes, it can occur during transportation and on the stalls of the shop; cotton blight is most conducive to the growth and development of the bacteria under high temperature and high humidity, and of course it is most conducive to its infection. Therefore, when it is hot and rainy in summer, we can see that a large number of eggplant rot and quickly grow long and dense white hair, and a large number of mature eggplant fruits are infected by Phytophthora infestans to form rotten eggplant.

Prevention and treatment: if the central disease plant appears in the initial disease, it should be removed and destroyed immediately and sprayed to prevent and cure it. From the beginning of the rainy season, sprayed with 1L / L Bordeaux liquid every 7 days for protection, the effect is very good. Once the disease occurs, the drug must be administered immediately. The medicament has 75% chlorothalonil 500-600 times night, 50% methyl thiophanate wettable powder 800 times, 40% ethyl phosphorus aluminum wettable powder 200 times, 64% poisonous alum 500 times, etc., generally sprayed every 7-10 days, 3-4 times in a row, in order to prevent the formation of drug resistance, different kinds of drugs should be used each time.
