| 摘 要： | 试验设置3种密度,随机区组排列,模拟长绒棉蕾期不同程度损害时所具有的产量补偿能力,结果表明,在同一密度下,棉株损害越轻,产量补偿能力越大;受害重的棉株前期恢复生长较快,但对后期的产量补偿力作用较小;在不同的损害程度下,随着密度的增加棉株产量补偿能力减小.

| Abstract: | By random arrangement of three densities and different hurt level in the bud period,the test imitated compensative ability of Long-staple Cotton after injury in order to help the management of harmed cotton.The result showed that,in the same density,the cotton plant suffering lighter injury had stronger compensative ability.The cotton plants suffering serious injury recovered rapidly in earlier stage,but this had less contribution to the output.Under the different harm degree,the cotton plants had less compensative ability as the density increased. |
