摘　　要：[目的]探讨黑色地膜覆盖在胡麻田杂草防治中的应用效果,为胡麻田杂草的综合治理提供参考。[方法]采用小区试验研究黑色地膜覆盖对胡麻田杂草的防除效果以及对胡麻的增产作用。[结果]黑色地膜覆盖对胡麻田杂草的防除效果显著,胡麻出苗后30 d的总体株防效和鲜重防效分别为88.57%和93.32%,60 d的总体株防效和鲜重防效分别为97.14%和89.00%。黑色地膜覆盖胡麻的株高、工艺长度、分茎数、分枝数、蒴果数、千粒重和产量均高于白色地膜覆盖。[结论]黑色地膜覆盖是有效防除胡麻田杂草的物理防除措施。[ Objective J The application effect of black film mulching on controlling weeds in linseed field to provide reference for comprehensive control. [ Method] Control effects on weeds in linseed field and increasing yield effect on linseed of black film mulching were studied through plot test. [ Result] The black film mulching had significant control effects on weeds in linseed field, and the overall plant and fresh weight control effects were 88.57% and 93.32%, respectively, in 30 days after linseed seedling, and the overall plant and fresh weight control effects were 97. 14% and 89.00%, respectively, in 60 days after linseed seedling. Plant height, process length, stem number, branch number, capsule um- ber, thousand grain weight and yield of linseed were higher than those of white film mulching. [ Conclusion] The black film mulching is effective physical measure for controlling weeds in linseed field.
