摘　　要：[目的]为配合马铃薯地上垄体栽培模式,采用化学除草方法防除田间杂草。[方法]分别选用4组药剂对苗前土壤封闭处理、苗后茎叶处理,以探讨不同处理对马铃薯田杂草的最佳防效。[结果]90%乙草胺乳油10 L/hm2+25%草酮乳油9 L/hm2+48%仲丁灵乳油28 L/hm2苗前土壤封闭处理对杂草防效最佳,达95.42%;48%苯达松水剂3.75 L/h m2+25%砜嘧磺隆水分散粒剂0.02 k g/h m2苗后茎叶处理对杂草防效最佳,达99.00%。[结论]试验地可以将这2个处理配合使用,以达到最佳的杂草防除效果。[Aims] In order to cooperate with the potato ground ridge cultivation mode, chemical weed control approach was used to control weeds in the experimental field. [Methods] And the four group pharmacies were selected whichdisposed of seedlings before soil closed and postemergence foliar treatment, to explore the best control effect of different treatments on controlling weeds on potato fields. [IRosults] The results showed that the best control effect was seedlingsbefore soil closed treatment with acetochlor 90% EC 10 L/ha＋oxadiazon 25% EC 9 L/ha＋butralin 48% EC 28 L/ha, and the control efficacy was up to 95.42%. Then the control effect of postemergence foliar was up to 99.00% treated withbentazone 48% AS 3.75 L/ha＋rimsulfuron 25% WG 0.02 kg/ha. [Conclusions] The cooperation application of the two treatment can be carded out in experimental field, to get the best effect.
