| 摘 要： | 为筛选出安全有效的除草市，分播后萌前和成坪时期，在室内和田间试验条件下研究了几种除草剂对马唐和稗草的防效。结果表明，播后萌前施药，果尔０．７５ｋｇ／ｈｍ＾２、恶草灵３．００ｋｇ／ｈｍ＾２和丁草胺在１．００ｋｇ／ｈｍ＾２用量下可以抑制马唐和稗草的萌发或杀死其幼昔。在已成坪的草坪上，恶唑禾草灵的用量为０．０７，。０．１５，０．３０ｋｇ／ｈｍ＾２，拿扑净０．３０ｋｇ／ｈｍ＾２，敌稗１．５０ｋｇ／ｈｍ＾２

| Abstract: | In order to select safe and effective herbicides, experiment was carried out to test some herbicides effect on large crabgrass and barnyardgrass at the stage of turfgrass germination and establishment. The result showed that, application of Oxyflu orfen 0.75 kg/hm 2, Oxadizon 3.00 kg/hm 2 and Butachlor 1.00 kg/hm 2 before emergence could control seed germination of large crabgrass and barnyardgrass. Application of Fenoxapropethyl 0^30 kg/hm 2,Sethoxydim 0.30 kg/hm 2 and Propanil 1.50 kg/hm 2 respectively, could kill the seedling of large crabgrass and barnyardgrass. |
