Fruit tree bag with stress
The correct use of fruit tree bagging technology can not only make the fruit large, improve the performance of commodities, increase sugar content, increase production and increase income, but also achieve the effect of white and tender fruit, delicate meat, and bright fruit color. The key should be the following: 1. Pre-bagging management. First, apply base fertilizer and pour bottom water. Secondly, we must do a good job in preventing and controlling diseases and pests and properly apply trace fertilizers. Such as spraying chlorothalonil, Tai Sang, carbendazim and other fungicides; spraying avermectin, imidacloprid and other insecticide killing class of drugs. In addition, for the lack of trace elements in fruit trees, boron, calcium, iron, zinc and other trace fertilizers can be sprayed. Do not bag for a few hours after spraying. If it is raining within 12 hours after spraying, it is necessary to promptly spray the medicine and the dew is not dry enough to be bagged. 2, correctly grasp the bagging time. Due to the different topography of different regions, the varieties of fruit trees are different. Therefore, generally from early May to late June, fruits should be bagged early after physiological fruit drop. 3, bagging method: first open the bag, with a fist to stay in the bag, open the vent slightly under the bottom, but not exposed, gently nest the young fruit bag and then fold 2-3 bags, The fold with the wire is placed at the outermost position. Then in one-half place (the young fruit is placed in the middle of the sleeve), the bag mouth is folded obliquely downward and the mouth of the bag forms a “∧†shape, so as to prevent pests, rainwater, and medicine from entering the bag. 4, pick bags. Generally picking the bag 10-20 days before fruit picking. When picking the bag, it is necessary to pay attention to the change of the weather. If it encounters even rainy weather, the paper bag can be torn off first, and the film bag remains, and the film can be naturally colored through the film.
