Watering, fertilizing, and pruning are properly controlled before the fruit is inflated. The water supply is guaranteed after the fruit enters the expansion period, and the watering is carried out in the morning. During the growth process of eggplant, the diseased, old, yellow leaves and diseased fruits should be removed in time, and the diseased plants should be removed. Wash hands with thick soapy water when pruning and forking to prevent virus infection during operation. The water can not be watered before the eggplant is inflated. When the length of the eggplant is 3 to 4 cm, the first topdressing and watering is carried out. Each acre is mixed with 15 kg of urea and 7 kg of potassium sulfate, and the watering amount is not suitable. is too big. The second topdressing fertilizer used 15 kg of urea per acre when the eggplant began to expand. The interval between the two top dressings was about 10 to 15 days. At the same time, we must actively take measures to protect the flowers, such as the use of plant hormone spray, to promote fruit set.
Pest control measures adhere to the plant protection policy of “prevention first, comprehensive preventionâ€. The open field uses a vibrating insecticidal lamp, a black light, a double-wave lamp, etc. to trap the pest. Pay attention to the rotation of drugs, strictly control the safety interval of pesticides, such as gray mold, 50% speed Keling powder 1500 times solution, use 3 times at 1 day interval; 64% mancozeb (antivirus cockroach) powder 500 times solution for cotton blight 3 times at 3 days interval; Verticillium wilt, Fusarium wilt can be used 50% carbendazim WP 500 times, 2 times at 5 days; mites with 22% dichlorvos 400g/mu powder, interval 5 It is used 5 times a day; the sassafras is used with 10% isopropylidene wettable powder 1000-1500 sputum, and used twice a day for 3 days.
If chemical pesticides are applied during the harvesting period, the pesticide residues shall be tested 1 to 2 days before harvesting, and harvested in time after being qualified. Basis for harvesting: The distance between the deep and shallow zigzag stripes below the fruit husk is narrowed by width and is suitable for harvesting. Early harvesting affects the yield, and the quality of late harvesting decreases, which also affects the growth of the fruit. Harvest time: choose to harvest in the afternoon or evening. In the morning, the branches are brittle and easy to break. The water content is low at noon and the quality is poor. To prevent the branches from being broken or to pull off the fruit stalks, it is best to harvest them with scissors that trim the fruit trees.
