Litchi suffered frost remedies

In winter, the temperature is low, precipitation is low, and low-temperature frost and freezing weather occur frequently. Caused most of the litchi damage to different degrees of frost, the top leaves were dead and dead. Therefore, we must do a good job of frost prevention in time. The specific measures are as follows:

Before the onset of frost, the whole park sprayed a new high-fat membrane insulation and anti-freeze. At the same time, it covered the canopy with thin film, dry straw, etc., and used young sheds or sheds for young fruit trees and nurseries. The white trunk of the fruit tree was brushed with a whitening agent and the main branch of the trunk was wrapped with straw. The whole tree is sprayed on the trees in an all-round and uniform manner to protect the tree from freezing, expel the overwhelming virus, infest the insects and reproduce, and urge the fruit trees to hibernate early and restore their vitality. The irrigation or spraying of orchards prior to the frost can increase the temperature of the soil, air, and ground surface and reduce the risk of frost. In the night when the frost comes, can use husks, weeds, branches, sawdust, straw, etc. around the orchard, and burn 4 to 6 piles per mu to increase the orchard's temperature and prevent frost.
