The role of apple bagging The bagging of apples is an accessory technology to increase the fruit rate of the fruits. Once the fruits are bagged, the peels can be made delicate and bright, the fruit spots are small, the appearance quality of the fruits is significantly improved, and the anthocyanin content of the red variety fruits can be promptly increased. , expand the coloring area, make the fruit color evenly, beautiful color, beautiful. In addition, in the reduction of pesticides, dust to the fruits of the residual, pollution, prevention, control of diseases, insects, birds, rats, bees and other fruit damage, reduce fruit rust, to avoid friction between branches and leaves, prevent sunburn and other mechanical damage and other aspects Have a good effect. However, Chunxi pointed out that although fruit trees are now bagged in certain climates, this method only improves the appearance quality of apples and does not increase the true nutritional value of the fruit. Choose qualified bagging Apple should pay attention to the choice of bagging problems? Shi Chunxi said that bagging should use quality-qualified paper bags. Poorly ventilated plastic bags and poor quality paper bags should be discarded. When selecting paper bags, good air permeability should be used as the main criterion for selection. Because paper bags are the environment in which apple grows for a long period of time, if the air permeability in the bags is poor, it will create a small environment of high temperature and high humidity, easily causing apple black. I’m sick. At the time of the Spring Festival, the reporter learned that in the apple growing province of Shaanxi, black spot disease has become the main hazard of bagging apples. Use proper bagging method Apple bagging should strictly follow the bagging technical specification. The correct method is to blow the air into the bag by kneading the two corners of the lower part of the bag and spread the bag. The young fruit should be hung in the bag. During the bagging process, do not bump the handle and young fruit, do not over-rub the fruit and bag, and do not put the leaves in the bag. The bag folds should be on the back of the slit. Finally, the folded bag should be clamped with a wire at the mouth of the bag. Pay attention to pesticide spraying before bagging For apple bagging, Shi Chunxi reminded the farmers in general that because apples are grown in bags after maturing, they cannot prevent and stop diseases and pests through direct pesticide spraying. Therefore, special attention should be paid to pesticide spraying before bagging. “Pesticide spraying before bagging is critical for the prevention of aphids, yellow powder and other diseases and insect pests,†said Chunxi. At the same time, Shi Chunxi emphasized that fruit growers should use high efficiency, low toxicity, low residue, safety, and stable performance as the main criteria for their selection.
