Occurrence and Preventive Measures of Low Temperature Freezing Injury in Yili River Valley
In January and May 2023,the low temperature freezing injury of fruit trees in Yili River Valley was investigated,and the low tem-perature freezing injury of fruit trees in Yili River Valley in winter and spring and its prevention and control technology were analyzed.The re-sults showed that apple,Xinmei,grape,apricot,apricot on the tree,cherry,peach and other fruit trees had different degrees of freezing inju-ry.The cold resistance of different varieties was quite different.The cold resistance of apricot on the tree,peach and cherry was poor,and the cold resistance of Xinmei,grape and Xiangfei crabapple was better.Cultivating fruit trees in the inversion zone could avoid the freezing injury of fruit trees to a certain extent,and management measures such as smoking,irrigation,and improving tree resistance could effectively reduce the degree of freezing injury.According to the actual production experience and a series of introduction experiments,the zoning suggestions of fruit tree planting were preliminarily put forward,which could better guide fruit tree planting and industrial development.
