Generally, water is properly controlled before the fruit enlargement period. Water is generally supplied in the morning when the fruit enters the swell period and the water supply is guaranteed. During the growth process of eggplant cultivation, disease, old, yellow leaves and diseased fruit must be removed in time to remove the diseased plant. Use thick soapy water to wash your hands when pruning or forking, to prevent virus infection during operation. The door must not be watered before the eggplant is swollen. When the door eggplant grows 3 to 4 centimeters, the first top-dressing irrigation is carried out. Each mu uses 15 kg of urea and 7 kg of potassium sulfate to mix and apply with water and pour. The amount of water should not be too large. The second topdressing at the beginning of the expansion of the door tomato, 15 kg of urea per acre, two fertilizer intervals of about 10 to 15 days. At the same time, we must actively adopt measures to preserve and protect fruits, such as the use of phytohormone sprays to promote fruit setting.
Second, pest and disease prevention
Adhere to the "prevention-based, comprehensive prevention and control" plant protection policy. Exposing pests with insecticidal lamp, black light, dual-wave lights, etc. Pay attention to rotation drugs and strictly control pesticide safety intervals, such as the use of 50% speed Kelin powder 1500 times liquid gray mold, use 3 times at intervals of 1 day; 64% use of evil cream Douding mancozeb zinc (antivirus) Powder 500 times, 3 times at intervals of 3 days; Verticillium wilt, blight can be used 50% carbendazim WP 500 times, 2 times at intervals of 5 days; Aphids with 22% dichlorvos smoke agent 400 g/mu spray The powder was used 5 times at intervals of 5 days; the tea plant was used with 10% imidacloprid WP 1000 to 1500 ml twice a day. Disable highly toxic and high residue pesticides.
Third, harvest
If chemical pesticides are applied during the growing season, pesticide residue testing shall be carried out 1 to 2 days before harvesting. Harvesting basis: The distance between the dark and light zigzag stripes below the fruit solanacea is narrow and narrow, which is suitable for harvesting. Early harvest affected the yield, and the quality of the late harvest decreased, but also affected the growth of the fruit, but the harvest should be harvested properly when the eggplant grows vigorously. Harvest time: Select afternoon or evening harvest. Morning branches are brittle, easy to break, low water content and poor quality at noon. To prevent breaking the branches or pulling off the stem, it is best to use scissors to trim the fruit trees.
In short, the above are the main aspects of the field management measures for eggplant cultivation technology, and the management of pests and diseases should be strengthened.
Grain powder is a kind of solid powder obtained by spray drying after breaking the wall of grain with high protein content. It can also be made into small molecular peptides by enzymolysis. It is a good helper for food additives and nutritional supplements.
