黑色地膜对胡麻田间杂草的防除效果

Control Effects of Black Film on Weeds in Linseed Field

以陇亚10为指示品种,研究了黑色地膜覆盖对胡麻田杂草的防除效果。结果表明,黑色地膜覆盖对胡麻田杂草防除效果显著,胡麻苗后30 d的总体株防效和鲜重防效分别为94.56%和97.27%,苗后60 d的总体株防效和鲜重防效分别为85.65%和59.66%。折合产量2 056.5 kg/hm2,较普通地膜覆盖增产255.6 kg/hm2,增产率14.19%。黑色地膜覆盖可作为防除胡麻田杂草的有效的物理措施。

The linseed variety Longya 10 as material,the control effects of black film on weeds in linseed field are conducted. The result shows that black film mulching on weeds in linseed field had significant control effects,the overall plant and fresh weight control effects are 94.56%and 97.27%,respectively,in 30 days after linseed seedling,the overall plant and fresh weight control effects are 85.65%and 59.66%,respectively,in 60 days after linseed seedling. The average yield of the variety reaches 2 056.5 kg/hm2,which is 14.19% higher than that of the common film mulching. Black film mulching is effective physical measure for controlling weeds in linseed field.
