How to prevent loquat trees from freezing in winter

At ordinary times, comprehensive management measures such as pruning, timely fertilization and pest control should be strengthened to cultivate robust trees, maintain a reasonable branch-fruit ratio and leaf-fruit ratio, and improve the frost resistance of trees.

2. Irrigation and grass cover?

Irrigation in the garden before low temperature can improve the cold resistance. If it is difficult to irrigate, you can irrigate thin human excrement and urine instead, or spray water on the tree crown and then cover it with weeds such as straw, or you can cover it with plastic film to keep warm, moisturize, protect fertilizer and protect underground roots.

3. The trunk is painted white

165438+1In the middle and late October, the trunk and large lateral branches are painted white to reduce the temperature difference between day and night, avoid frost cracking of bark and enhance the cold resistance. The mixture of 10 part of quicklime, 30 parts of water, 0.2 part of salt and 1.5 part of crystalline sulfur can be mixed and coated on the trunk, which can not only reflect light to improve the frost resistance of trees, but also help to reduce the harm of branch pests.

4. Cover with cold-proof cloth to prevent freezing.

Cold-proof cloth has good microclimate regulation function, can insulate heat, improve environment and growth conditions, and can also play a protective role. ?
