Grape bagging can avoid the harm of birds, and block the channels for the spread of germs in branches, leaves and soil to the ears and fruits. It has a good effect on the prevention and treatment of anthracnose, powdery mildew and white rot. It can reduce the physiological diseases such as sunburn and fruit shrinkage, and effectively control insects such as chafer and beetle, thereby reducing pesticide pollution. In addition, bagging can also improve the appearance and quality of the fruit, reduce the cracking of the fruit, make the color uniform and bright, the peel is delicate and shiny, and the fruit powder is increased. At the same time, the intrinsic quality of the fruit is improved and the fruit flavor is improved.
Bagging is generally carried out after the end of sparse granulation to the young fruit expansion period. It is advisable to bag grapes such as broad bean size. Before bagging, carry out a comprehensive control of the combination of fungicides and pesticides on a sunny day, as soon as possible after the medicine is dried Bags are made with grape-specific fruit bags.
White bag is generally used for bagging, and green bagging can be used for sunshine roses, which will look better when mature.
If the gift box is put on the market, you can tear the bottom of the bag and turn it up or remove it after the grapes are turned into the bird-proof net. If you do not have the bird-proof net, you cannot remove the bag. Wholesale bags are generally not removed from the market, so as not to damage the fruit powder layer during harvesting, transportation, and sales.
