近年来,我县部分小麦屡次倒伏,倒伏后,叶片茎秆互相重叠,严重影响光合作用的正常进行,植株输导组织遭到损伤,养分和水分运转受阻,正常代谢活动受到破坏,千粒重明显下降。下部叶片和部分单茎因得不到光照甚至引起死亡,影响穗数。所以小麦倒伏后,造成粒少、粒秕,产量降低。 In recent years, some counties in our county repeatedly lodging, lodging, leaf stems overlap each other, seriously affecting the normal photosynthesis, plant tissue damage, nutrient and water operations blocked, normal metabolic activity was destroyed, a significant reduction in grain weight . The lower part of the leaves and some stems due to lack of light or even cause death, affecting the number of ears. So after lodging of wheat, resulting in less grain, grain 秕, reduce production.
