冬季低温会给果树造成伤害,尤其是东北地区冬季漫长,酷寒干燥,很多地区最低气温在零下四十度以下,果树常受各种不良环境危害,影响产量,严重时可造成死树毁园。因此,除生育期要加强管理增强抗性外,果树的越冬保护至关重要,值得重视。1、掌握防寒方法:各种果树的防寒方法都是由果树科技工作者通过多年的、大量的试验研究总结出来的,因此在生产中都是行之有效的。目前有些果园不进 Winter low temperature will cause injury to the fruit trees, especially in the winter in Northeast China long, cold and dry, the lowest temperature in many areas below minus 40 degrees, the fruit trees are often endangered by a variety of adverse environment, affecting the yield, serious dead can cause destruction. Therefore, in addition to strengthening the management of the growth period to enhance resistance, the protection of fruit trees overwintering is of paramount importance. 1, master the cold method: a variety of fruit trees cold method by the fruit tree scientists through many years, a large number of experimental studies concluded that in the production are effective. At present, some orchards do not enter
