冰雹灾害经常会对棉花生产造成威胁,特别冀东棉区在6月上中旬棉花现蕾期前后经常会遭受雹灾。一旦遭受雹灾,轻则枝断叶碎,重则打成光秆,对棉花正常生长造成重大影响。但棉花具有很强的生理补偿作用和再生能力,一般受雹灾后只要加强管理仍能获得收成,因而不要轻易翻种。按照冀东的光热资源和气候特点,6月20日前受灾的,70%棉株只要有主茎,一般不翻种;6
Hail disasters often pose a threat to cotton production. In particular, the eastern part of the eastern part of the eastern part of the eastern part of the eastern Taiwan area suffered a hail disaster before and after the cotton budding period in mid-June. In the event of a hail disaster, light branches are broken, while heavy ones are harvested. They have a significant impact on the normal growth of cotton. However, cotton has a strong physiological compensation and regeneration capacity. Generally, harms can only be obtained if there is still more management after the hail. Therefore, cotton should not be easily turned over. According to the light and heat resources and climate characteristics of Jidong, 70% of the cotton plants affected by June 20 were affected by the main stems and generally did not change their type. 6
