补充资料:倒伏
倒伏 lodging 直立生长的作物成片发生歪斜或全株匍倒于地面的现象。大多发生在作物生育的中后期,它会使作物的产量和品质降低。一般分根倒伏和茎倒伏两种。根倒伏表现为茎不弯曲而整株倾倒于地面。常因根系弱小、分布浅或根受伤,当灌水过多或降雨过多而土壤软烂时,固着根的能力降低或遇风时发生。茎倒伏即作物茎秆呈不同程度的弯曲或倾斜,有时下折。常因茎节间尤其下部节间延伸过长,机械组织发育不良,或茎秆细弱、节根少,遇大风或其他机械作用,茎的中、下部承受不住穗部或植株上部的重量而引起。茎秆受病虫为害时也易弯折。倒伏打乱叶的分布,部分叶片因相互压盖而影响光合作用,甚至变黄腐烂,影响产量。早期发生根倒伏时,使作物花数,结实数和麦类作物的分蘖减少;后期倒伏影响授粉结实和灌浆,甚至出现“穗发芽”等。作物抗倒伏性的强弱与品种特性、施肥、灌水和种植密度等有关。尤以氮肥量或灌水过多、密度过大时发生倒伏较多。通过选用耐肥、水矮秆和抗倒伏的品种、科学管理和生长调节剂等措施预防倒伏。 |
