摘要/Abstract

摘要： 研究结果表明,林带背风面27H范围内,林网具有不同程度减轻棉株倒伏及产量损失的功能,有效防护范围为0.42～23H,最大籽棉产量和衣分率效果区为10～13H.与受灾区相比,保护区的籽棉产量增加45.01%,皮棉产量增加52.69%.整个林网内的籽棉产量增加2994%,皮棉产量增加3506%.

Abstract: The studies show that within the scope of 27 H from sheltered side of farmland windbreak, forest net has the functions of reducing cotton lodging and its yield loss to a certain extent.The effective protection zone ranges from 0.42 to 23 H, and the maximum effective zone for unginned cotton yield and gin turnout percentage is from 10 H to 13 H. Compared with damaged zone, protection zone has an increase of 45.01% for unginned cotton yield and 52.69% for ginned one. Within the whole forest net, the unginned cotton yield is increased by 29.9%, and the gined one by 35.06%.
