鄂东南低山丘陵区五节芒防除试验

Experiment on Control of Miscanthus floridulus in the Low Mountains and Hilly Area in Southeastern Hubei

摘要:

摘要：为筛选出防除五节芒效果较好的除草剂，利用农达(41%草甘膦)、百草枯、精喹禾灵三种除草剂，开展鄂东南低山丘陵区五节芒防除试验，结果表明：三种除草剂除草效果与施药剂量、施药时间呈正比时，三种除草剂均可有效控制五节芒生长；但综合施药和成本情况，确定出农达（41%草甘膦）为防治五节芒优选除草剂，施药剂量以3 000 mL·hm-2为宜。

Abstract:In order to select better herbicide for Control Miscanthus floridulus,we carried out the experiments on controlling Miscanthus floridulus control experiments with roundu(41% glyphosate),paraquat and 10% quizalofop-p-ethyl in the low mountains and hilly area in southeastern Hubei.The results showed that the weed control effect of these three kinds of herbicide were proportional to their dose and spraying duration.Three kinds of herbicide could all control its growth.And the pesticide dose and the cost synthetically determined that roundu(41% glyphosate) and within the application dosage in 3 000 mL·hm-2was the optimal selection.
