【摘要】 采用苯达松、2,4-D丁酯、高效盖草能(10％乳油)3种除草剂对沟叶结缕草草坪进行了杂草化学防治研究。结果表明,苯达松(25％水剂)每15 kg水可加至80 ml左右,2,4-D丁酯(72％乳油)每15 kg水可加至25 ml,高效盖草能(10％乳油)每15 kg水可加至10-15 ml,每667m2控制用水25-30 kg可取得较好效果。但高温季节除草剂容易对草坪产生药害,施用时应在杂草幼苗期进行,并降低药剂浓度,以提高对草坪的安全性。更多还原

【Abstract】 In this study, we compared the effects of herbicides (bentazone, 2, 4-Dbutyl, haloxyfop r-methyl) on weeding in manilagrass turf. We found that 80ml bentazone (25%) with 15kg H2O, 25ml 2, 4 Dbutyl (72%) with 15kg H2O, 10-15ml haloxyfop-r-methyl (10%) with 15kg H2O, and 25-30kg H2O /667m2 could effectively kill weeds. In the season of high temperature, in order to insure the safety of turf grass, herbicide should be applied in the seedling of weeds with lower concentration.更多还原
