(1) Spraying before bagging. Bags are sprayed 2-3 times before the rotation, and the bagging is completed within 2-3 days after the last spraying.
(2) Breeding fruit bags. Choose double-layer or single-layer paper bags with a width of 18-20 cm and a width of 22-25 cm. The tying wire is a galvanized iron wire of No. 24 or other non-corrosive zipper. The color of the paper bag is black and light, and the light transmittance is moderate. Good air permeability, moderate softness, good tensile strength, high tear index, low water absorption. The content of harmful substances is low and there are registered trademarks. The minimum temperature in winter may be lower than -3°C in the year or area. Double-layer paper bags should be used.
(3) bagging time. The full bagging period is from mid-July to mid-August, and the “antifreeze and yellowing†bag is suitable for the end of October to the end of November.
(4) Specification bagging technology. Soak the upper 4-5 cm of the paper bag in water for 20-30 minutes until it is soft and soft. Then use a hand bag to open the bag so that the fruit is suspended in the center of the bag. The handle is placed at the base of the bag opening and the bag mouth is horizontal. The folds are tightened, and the wire is bent into a "V" shape to hold the mouth of the bag: or about 3 cm long (including part of the fruit branch) into the upper end of the bag, with the handle as the axis. Fold tightly from the center of the bag to the two sides, and wrap the tying wire around the handle in a clockwise or counterclockwise direction. It is forbidden to dry the bag with liquids, rainy days, and non-“net fruits†to prevent the fruit from being tightly packed in bags, tear out the wire, and bundle the wire into a “ring tie†fruit handle or put fruit branches, leaves, twigs, etc. into the bag. The bag mouth is tied tightly (clips) too loose and the mouth of the bag is horned. Weak trees and water shortage trees should not be bagged.
(5) Management after bagging. 10-15 days after the end of the paper bag, spray pesticide to the orchard to “clean the gardenâ€; replace the damaged fruit bag in time: carry out bagging together with fruit picking at the time of collection; timely recover, sort, disinfect, and store the bag.
