摘　　要：通过对雹灾后的5个陆地棉品种(系)的现蕾强度、成铃强度、净同化率(NAR)、群体生长率(CGR)等主要形态生理指标和产量的研究,得出冰雹对棉花生长发育及产量的影响与棉花品种的抗逆性大小、冰雹的危害程度、以及受灾后所采取的管理措施有关;筛选出了受雹灾后,具有较强恢复力和自养能力的品种(系),同时提出了不同受害级别棉花的抗雹灾农艺措施。According to the field experiments and observation, this paper studied main physiologyical index and yield of five cotton breeds (Series) after the calamity caused by hail. The results indicated that the influence of hail on cotton growth has relations with the resistance of the different cotton breeds, the hail danger degree and taking effective measures. Meanwhile, the breeds of cotton which have stronger growth recuperability and capability of survive by themselves and the different agricultural measures with resisting the hail calamity were proposed.
