The cold winter weather, the freezing of the soil, and the dry and windy weather often cause some tree branches to dry due to excessive water loss. It is commonly known as "drafts", also known as "pulling tips." Especially young fruit trees, branches are tender and weak, in winter and spring. It is easy to draw, and it can cause dead plants when serious. To prevent fruit trees from drawing, the following measures can be taken: 1. Filling in the winter water before the soil is frozen can make the fruit trees fully absorb water and prevent physiological drought, which is of great benefit for reducing the number of drawstrings and shortening the length of drawstrings. In February-March, pouring early spring water can prevent spring drought, and at the same time, it can use the latent heat released by water to promote the thawing of soil in advance, so as to facilitate the absorption of water by the root system and supplement the loss of water in the tree body as soon as possible to prevent the occurrence of spring drawing. 2. For newly planted young fruit trees, the tree can be gently pressed onto the ground in winter to bend the upper part of the rhizosphere, and then cover 15 cm to 20 cm thick wet soil. This will not only reduce the water evaporation of the tree, but also play a role in insulation and cold. For large non-bending fruit trees, a culturing method can be adopted, in which a crescent-shaped soil raft with a height of 60 cm or more is cultivated on the north side of the trunk to change the microclimate conditions around the tree, increase the ground temperature, shorten the soil freezing period, and make the root system Absorb moisture in time to reduce or prevent drawing. 3. Use lime sulfur, salt, soybean milk 0.5 kg, lime 3 kg, add appropriate amount of water to mix into the coating agent, brush on the main trunk of young fruit trees, which can reduce the water evaporation of the tree, prevent freezing injury, and both Kill the role of overwintering eggs. In addition, it is also possible to use Vaseline cream to spread the branches of fruit trees. To reduce the evaporation of water, prevent drawing. 4. The use of straw or plastic film to wrap the branches of young fruit trees can also reduce the evaporation of water and cold wind, and has a good effect on the prevention of pumping.
