采用田间试验研究了土壤封闭除草剂在全膜双垄沟播玉米田垄沟底和全地面的施用效果。结果表明：在垄沟底施用除草剂，玉米主要农艺性状均高于全地面施药和空白对照；玉米产量较全地面施药增产0.61%，较空白对照增产25.32%；施用量仅为全地面施药的1/4，成本降幅达到66.12%；杂草群落密度和鲜重分别被控制在4株/m2和13 g/m2以下，阔叶杂草株防效和鲜重防效均在98%以上，禾本科杂草株防效和鲜重防效分别在87%和93%以上。建议在全膜双垄沟播玉米生产中用垄沟底施药来替代全地面施药。

Effects of soil herbicides on weeds in whole film double furrow were tested by field trial. The results showed that the main agronomic traits of furrow bottom spraying were higher than those of whole ground application and blank controller. Compared to blank controller and whole ground, furrow bottom could increase corn yield, with the rates of 25.32% and 0.61%. Herbicides doses of furrow bottom were less than whole ground, the cost decline was 66.12%. Weeds density and fresh weight of furrow bottom were below 4 strains and 13 g per square meter. The control efficacies and fresh weight control effects on broadleaf were above 98%, on gramineous weeds reached 87% and 93%, respectively. Furrow bottom spraying was suggested to replace the whole ground application in whole film double furrow corn field.
