| 摘 要： | 北方地区的旱直播稻田杂草群落属于水旱共生型复合群落，具有2个杂草发生高峰期，第1次高峰期为旱生型杂草，第2次高峰期以水生及湿生型杂草为主导群落．用百草枯除苗前大草，秧苗3叶期用“快杀稗＋苯达松”茎叶处理，杂草综合防效可达95％以上．

| Abstract: | The weeds community in the dry direct seeding paddy field is compound made of both water plants and xeromorph plants which have two fastigiums.The xeromorph weeds are the most damage weeds to rice during the first fastigium,while the water weeds are dorminant types in the second fastigium.The comprehensive control rate of weeds is more than 95% using Paraquat to the early weeds,and spraying "Quinclorac Bentazon" during three leaves period of the rice. |
