First, the bag mouth end 6-7cm is immersed in water to make it moist and soft, making it easy to contract the bag mouth. When bagging, first use your hands to open the paper bag to make the paper bag bulge, and then put the whole ear into the bag from the bottom up. Then shrink the mouth of the bag to the ear handle and fasten it tightly with the sealing wire on one side. Keep a 1-1.5cm paper bag above the wire. When bagging, it is strictly forbidden to knead the ear with your hands.

If there is no rain and no dew at night, the cover will be finished within two days at the latest. Vineyard area is large, can be divided into pieces, according to labor, bagging speed, etc., calculate the number of bags in a day, as much as you can, spray as much medicine. Do not spray after the liquid is not dry bagging, so it is easy to cause rotten fruit. It should also be noted that when bagging, try to avoid touching the fruit with your hands, and be sure to tie the upper mouth tightly to prevent Rain Water from leaking.

The grapes should be sprayed on both sides of the hedge, and the scaffolding should also be sprayed on both sides of the ear; spray effective medicine, such as mancozeb, methyl topazine, DuPont Fuxing, etc., do not spray fake medicine. When spraying, the spray head of the sprayer should choose a fine spiral piece, which is conducive to the fine and uniform spraying.
