摘要
2023年1月和5月进行了伊犁河谷果树低温冻害调查,分析了伊犁河谷果树冬春两季低温冻害及其防控技术.结果表明:苹果、新梅、葡萄、杏李、树上干杏、樱桃、桃等果树均有不同程度的冻害.不同品种的抗寒性差异较大.树上干杏、桃和樱桃品种的抗寒性较差,新梅、葡萄和香妃海棠抗寒性较好.在逆温带区域栽培果树在一定程度上可规避果树冻害,烟熏、灌溉、提高树体抗性等管理措施能有效减轻冻害程度.根据实际生产经验和一系列引种试验,初步提出了果树种植的分区建议,可以更好地指导果树种植和产业发展.
Abstract
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.
