1, bagging period. It is generally performed after physiological fruiting is stopped and fruit is set. That is, young fruit growth is obviously stable, the sooner the better, mastering the bagging from the end of April to the beginning of May, and it is better to complete the bagging work within 15 days. 2, bagging should choose to be carried out on a sunny day. Must be sprayed before the bagging fungicide to remove the bacteria attached to the fruit surface. If the bagging period is affected by rain, after the rain, the bags should be bagged after spraying the medicine again. 3. The day before bagging, the mouth portion of the whole bundle of paper bags shall be soaked in water. The moist mouth of the bag is conducive to the bagging operation and the tight bag opening. 4. When bagging, wear a work apron on the chest and a paper bag with a second layer pocket on the skirt. After removing the paper bag, insert the paper bag into the paper bag with four fingers and open the paper bag on both sides. Put the young fruit into the middle and insert it with the paper bag. There is a thin wire to tie the bag. Avoid damage to fruit shank during operation, make fruit fall off, and avoid sticking fruit surface with paper bag, so as to avoid occurrence of fruit rust class or uneven coloration. 5, bagging should be difficult. That is, after the first tree is placed on the back of the tree, the outer surface of the inner frame will be placed on the outer surface of the tree to prevent it from colliding with the fruit and paper bag during the operation. 6. Try to make the pear fruit evenly distributed on the tree when it is bagged. Only one fruit can be left in one inflorescence, and one fruit can only be set in one bag.
