Trilogy of Eggplant High Yield Management
Watering, pruning, and fertilization. Before the fruit enlargement period, control water properly. After the fruit enters the expansion period, water supply is guaranteed, and watering should be carried out in the morning. During the growth of eggplant, the diseased, old, yellow leaves and fruit should be removed in time, and the diseased plants should be removed. Wash hands with thick soapy water during pruning and cross cutting to prevent virus infection during operation. The door eggplant cannot be watered before it expands. When the door eggplant is 3 to 4 cm long, the first topdressing irrigation is carried out. The mixed hole is applied with 15 kg of urea and 7 kg of potassium sulfate per acre, and the watering is not suitable. Big. The second top dressing began when the eggplant began to swell, with 15 kg of urea per mu, and the interval between two top dressings was about 10 to 15 days. At the same time, we must actively take measures to preserve flowers and fruits, such as the use of plant hormones to spray flowers.
Pest Control. Adhere to the "prevention first, comprehensive prevention" policy. In the open field, use frequency-vibration insecticidal lamps and double-wave lamps to trap and kill insects. Pay attention to the rotation of medicines and strictly control the safety interval of pesticides. Botrytis can use 50% Sukeling powder 1500 times solution, used 3 times a day; 3 times with a 64% generation of mancozeb powder for cotton blight disease, used 3 days apart. 3 times; 500 times of 50% carbendazim wettable powder can be used for Verticillium wilt and Fusarium wilt, used twice every 5 days; aphids sprayed with 22% dichlorvos smoke agent 400 g/mu, used 5 times every 5 days; The tea yellow mite uses 10% imidacloprid wettable powder 1000 ~ 1500 涪液, used twice every 3 days.
Harvest period. Those who have applied chemical pesticides shall be tested for pesticide residues 1 to 2 days before harvest. After being qualified, they shall be promptly harvested and marketed in graded packages. Harvesting basis: The distance between the deep and shallow zigzag stripes under the fruit sepal (eggplant) from wide to narrow is the appropriate harvest period. Early harvesting affects yield, the quality of late harvesting declines, and it also affects fruit growth. However, when eggplant seedlings grow vigorously, late harvesting should be appropriate. Harvest time: choose harvest in the afternoon or evening. The branches are brittle in the morning, easily broken, low in water content at noon, and of poor quality. It is best to harvest them with scissors that trim the fruit trees, to prevent breaking the branches or pulling off the fruit stems.
