摘　　要：草坪是重要的景观元素,具有重要的生态功能和美学观赏价值,但草坪长时间超过生长年限,会不断发生退化现象,导致草坪中长出大量的丝茅杂草,影响了草坪的观赏效果。为了有效遏制丝茅的生长,选用2种混配除草剂、2种单一除草剂对草坪中的丝茅进行除草效果试验。试验结果表明:混配除草剂高效氯吡甲禾灵+油酸甲酯助剂对丝茅的除草剂效果最佳,药后30 d对丝茅的防除效果可达到100%;草坪隆11号对丝茅的防治效果可达到87.1%;混配药剂精噁唑禾草灵+油酸甲酯助剂+氯氟吡氧乙酸异辛酯+甲嘧磺隆,对丝茅的防治效果可达到57.7%。本文的试验结果将给草坪生产和养护人员防治丝茅提供一定的参考意见。As an important landscape element,lawn has important ecological functions and aesthetic ornamental value.However,if the lawn exceeds the growth period for a long time,it will continue to degrade,resulting in a large number of silk grass weeds growing in the lawn,which affects the ornamental effect of the lawn.In order to effectively curb the growth of Imperata koenigii,two kinds of mixed herbicides and two kinds of single herbicides were seleceted to carry out the herbicidal effect test on the Imperata koenigii in the lawn.The results showed that the herbicide combined with highly effective haloxyfop-methyl and methyl oleate additive had the best herbicide effect,and the control efficiency can reach 100%at 30 days after treatment.The control effect of Cao Pinglong 11 can reach 87.1%.As for the herbicide combined with fenoxaprop-p-ethylmethyl.methyl oleate additive,fluroxypyr-mepthyl,and sulfometuron-methyl,the control efficiency on Imperata koenigii can reach 57.7%.The experimental results in this paper will provide certain reference opinions for lawn production and maintenance personnel in the control of Imperata koenigii.
