| 中文摘要: |
| 覆膜至播种期土壤持续干旱条件下对2种除草地膜在全膜双垄沟播玉米田中的应用效果进行了研究。结果表明, 化学除草地膜、黑色地膜和白色地膜覆盖下玉米出苗率依次为76.39%、69.44%和81.48%, 三处理间差异不显著, 与白色地膜相比, 化学除草地膜和黑色地膜覆盖下, 玉米株高略有降低, 降幅依次为0. 04%和3.29%; 化学除草地膜、黑色地膜和白色地膜覆盖下, 玉米株高整齐度依次为29.23、50.24和37.18, 三者差异不显著; 化学除草地膜和黑色地膜覆盖下, 玉米成穗株率均略低于白色地膜, 降低幅度依次为0.86%和2.72%; 化学除草地膜和黑色地膜均较白色地膜有一定的增产作用, 增产幅度分别为9.71%和10.56%; 化学除草地膜的株防效和鲜重防效分别为4.38%和23.09%, 黑色地膜的株防效和鲜重防效分别为96.72%和99.20%, 两者差异极显著。黑色地膜在全膜双垄沟播玉米栽培中具有较大的应用价值, 化学除草地膜在土壤持续干旱条件下不宜推广。 |

| Effect of functional films on corn field of whole plastic-film mulching on double ridges were investigated in this paper. The results showed that corn seedling emergence rate using weeding film, black film and white film were 76.39%, 69.44% and 81.48%, respectively. Compared with the white film, the corn height covered with black film and weeding film was slightly reduced by the rate of 0.04% and 3.29%. Corn height uniformity under three films were 29.23, 50.24 and 37.18, and no significant difference were found. Corn spike rate covered with weeding film and black film was lower than white film, which reduced 0.86% and 2.72%. Compared to the white film, black film and weeding film had increased corn yield, with the increase rate of 9.71% and 10.56%. Plant control effect and fresh weight control effect covered with weeding film were 4.38% and 23.09%, while black film were 96.72% and 99.20%. Black film had higher control effect on weeds than weeding film. |
