一九七六年秋冬至一九七七年春,我省受低温冷害的影响,使百万亩冬小麦发生了程度不同的冻害,严重地区,冬小麦全部冻死,给生产造成一定损失。为了摸清各地冬小麦冻害情况,我们重点深入到冬小麦产区旅大、营口、鞍山、辽阳、锦州、朝阳、本溪、丹东等八个市地的十六个县(区),的二十八个社队,进行现场考察和调查研究,通过查阅有关气象资料,初步分析了冬小麦冻害原因和防御效果,现将我省冬小麦冻害情况和防御效果的考察结果,报告如下,供参考。
In autumn and winter of 1976 to spring of 1977, affected by chilling injury, millions of mu of winter wheat suffered freezing damage in different degrees. In severe areas, winter wheat was all frozen to death, causing some losses to production. In order to find out the situation of winter wheat frostbite in various places, we focused on the twenty-eight counties (districts) of the eight cities and districts of LW, including Luda, Yingkou, Anshan, Liaoyang, Jinzhou, Chaoyang, Benxi and Dandong. The commune and brigade team conducted field investigation and investigation and research. By referring to the relevant meteorological data, the causes of frost damage and the defensive effect of winter wheat were analyzed. The results of the investigation on the frost damage and defensive effects of winter wheat in our province are reported below for reference.
