Young tree trunk base soil. For 1-3 year-old saplings, it is easy to get rid of the trunk by cold-proofing the saplings. Therefore, a 50cm-high cone-shaped mound can be cultivated at the base of the trunk to prevent cold. The trees are white or wrapped. After the whitening time is defoliated in the fruit trees, the ratio of raw materials is: quicklime, lime sulfur, salt, and water are prepared at a ratio of 6:1:1:20. In the preparation process, the calcification is first opened, the oil is poured into the well-stirred mixture, and then the water is mixed into the lime milk. The lime sulfur mixture and the salt water are added into the left and the adhesive is added. This kind of whitening can be painted white on the trunk and white on the trunk. The role of quicklime to whiten, reduce the temperature difference; lime sulfur combined with the role of disease prevention, the equivalent of spray 1 Baume degrees of lime sulfur; salt and grease are mainly water retention. Before the spring sprout, it would be better to spray lime sulfur again. Second, wrapping plastic sheets, newspapers, etc. can also play a role in cold. Root thick organic fertilizer (or straw, weeds). The thick organic fertilizer on the top of the tree plate, the organic fertilizer in the fermentation process, can generate heat to increase the temperature, protect the roots safe winter. In the sand land, it should be thicker. Robust tree body. Fertilizing soil fertility and increasing organic manure can increase soil organic matter content, rejuvenate tree vigor, and increase tree resistance. General Mushi organic fertilizer 5000 kilograms. Appropriate choice of trees suitable for cold resistance. Don't plant chestnuts on tuyere and sandy lands; chestnuts on inhospitable mountainous regions should be made of robust trees and organic fertilizers should be applied more. Secondly, it is necessary to choose more suitable cold resistant varieties. Accelerate Freeze Dried Fig is made of selected ripe figs.
