Scientific management measures after fruit trees are harvested 1. Foliar spray fertilizer: It can promote the further development of flower buds, and it can increase production by more than 10% in the coming year. Therefore, from the fruit harvest, every 10-15 days, spray 0.5% urea solution, while adding 0.3% -0.5% of potassium dihydrogen phosphate or the same concentration of diammonium until the leaves fall. Second, the autumn base fertilizer: generally every production of 50 kilograms of fruit requires 1.2 kilograms of pure ammonia, 0.5 kilograms of phosphorus, 1 kilogram of potassium, converted into 100 kg of urea and 0.25 kg of urea. 1-3 years of saplings with 2,500 kg of miscellaneous fertilizer per acre, which increases with age; trees from 6-10 years old with 3,000 kg of composted soil, 10 kg of superphosphate, 10 kg of pure nitrogen, and potassium chloride 16.5 kilograms (if no organic fertilizer is available, 10% of production can be applied to slag). The above amount is an annual output of 2000 kilograms per mu. The application of basal fertilizer should be carried out before freezing. Third, pest control: After harvesting, the whole garden sprayed a fungicide and insecticide, apples, peaches, pears, plums, etc. with 50% carbendazim 1000 times, with 65% dexamethasone 400-500 times. liquid. It can control 1000-fold dimethoate to prevent pests such as Daphnia majus. Bactericidal pesticides can be combined with foliar sprays. Scrape rot, dry rot lesions and old bark in a timely manner to focus on burning, scrape the wound with 5 Baume degree of lime sulfur or 1% copper sulfate solution. In severely diseased orchards, 40% of the Aspergillus fumigatus arsenic or bactericidal king is sprayed on the entire tree after defoliation, which can significantly reduce overwintering pests. When the trunk is painted white and painted, it should be thickened to the sunny side. Fourth, take heart cuttings: control its continued growth, promote the accumulation of nutrients in shoots, so that branches are enriched. 5. Deep turning: Turning the land can be combined with fertilization. The depth of the ground is 30-60 cm. The soil with heavy weight can add proper amount of sandy soil. The sand orchard can be mixed with a small amount of clay. Sixth, winter: In addition to foliar safety over winter, spraying potassium dihydrogen phosphate, white coating, irrigation winter water, etc., but also use package grass, plastic film package, tree plate shop plastic film, soil, painted antifreeze and other methods.
