摘  要:
为探明300 g/L丙草胺EC对水稻抛秧田杂草的防除效果以及杂草养分、水稻产量的影响,设计了不同用量丙草胺防除抛秧田杂草的试验,以期为该农药推广提供依据。试验结果表明,300 g/L丙草胺EC对水稻抛秧田杂草稗草、异型莎草、鸭舌草有良好的防除效果,防效高达92%以上,且对水稻的增产效果显著,比未施药的对照增产20.38%~30.62%。300 g/L丙草胺的施用,既节省了劳力,又提高了经济效益,是一种防除水稻抛秧田一年生杂草的高效药剂。

摘  要:
In order to provide guidance for the promotion of pretilachlor,trials were conducted to evaluate the weeds control effects of 300 g/L pretilachlor EC in throwing-seedling field and its influence on nutrient,rice yield and economic benefits.The results showed that 300 g/L pretilachlor EC had good control effects over 92% on Echinochloa crusgalli(L.) Beauv,Cyperus difformis L.,Monochoria vaginalis(Burm.F.) which reach.And after the application,the yield was increased by 20.38~30.62% compared with control.Application of pretilachlor EC at 300 g/L significantly saved labor and increase economic benefits,was an effective herbicide to control annual weeds in throwing-seedling rice field.
