Frost damage prevention of fruit trees
After picking the white fruit from the tree trunk, the trunk and the main branch of the fruit tree are uniformly coated with whitening agent in time to prevent freezing and to kill pathogens, eggs and adults hidden in the trunk. The preparation method of whitening agent is quicklime, sulfur powder, salt, vegetable oil, and clear water according to the ratio of 10:1:1:0.1:20. Before wrapping the tree with large freeze, use a straw or straw rope wrapped around the trunk or the main branch to prevent the cold wind from invading and reduce the loss of water from the trunk. Before winding, it is best to soak the wounds in lime water for two days to disinfect and sterilize, to prevent pests from taking the opportunity to invade the fruit trees. In the coming spring, when the grass is dissolved, the cover will be burnt to destroy the overwintering pests. Antifreeze for winter irrigation Because orchards are mostly built on hillsides, hills, and rivers, shallow soil layers and poor water retention, it is most likely to cause fruit trees to suffer drought damage. Therefore, before winter, fruit trees should be watered twice and after irrigation. When it is slightly dry, the soil surface should be lightly cut to cut off the capillary tube and reduce the loss of water and the accumulation of salt and alkali. The root neck of the fruit tree is the most difficult to resist the cold invasion, especially the young trees, which are more vulnerable to frost damage. Therefore, soil must be soiled at the junction of the ground part of the tree body and the underground part before freezing, with a thickness of about 30 cm, and it will be removed when it is defrosted in the following year. The increase in smoke and fume smoke should be performed at the coldest night in winter. The fuel is burned with chopped firewood, chopped weeds, sawdust, and oyster shells. It ignites around midnight. It is advisable to control the fire and use dark smoke and thick smoke. The burning point should be set on the uptake, usually no less than 4 per mu.

Covered with rice straw, wheat straw, dry grass, corn stalks, etc., the ground cover can prevent cold winds from invading rhizomes, reduce frost damage, reduce soil moisture evaporation, and protect the temperature and increase the temperature. When covering, the straw and other coverings should be cut into small pieces of about 20 cm in length, and evenly covered and then covered with a layer of soil to prevent the wind from being blown away. After the mulch is rotted, it can also become an organic fertilizer for the growth of fruit trees. For saplings born within three years, a one-meter square mulch can also be covered in the tree tray before frost, which can increase soil temperature and maintain soil moisture.
Most products are flaky and shorts type. Use adhesive sheets to connect into a pair of shorts. The adhesive sheet also has the function of adjusting the waist size so as to fit different fat and thin body shapes.
Generally, the structure of diapers is divided into three layers from the inside to the outside.
