| 中文摘要: |
| 1998～2001年对江苏省5个不同生态区125个麦套稻田示范点的田间杂草发生情况进行了调查分析,初步掌握了麦套稻田杂草的发生特点,主要表现为种类多、发生早、群体大、危害重。免耕方式、前茬余草和前期田间管理粗放是造成杂草发生严重的原因。通过试验提出了"前封后杀"的化除策略,并研究出多项配套化学除草技术,促进了超高茬麦套稻田技术的大面积推广应用。 |
| 英文摘要: |
| The weeds in 125 model rice-interplanted wheat fields in 5 different ecological areas of Jiangsu Province were investigated during 1998-2001. The occurrence of weeds was characterized by many species, early breakout, big population and serious damages, which was caused by plowing-free style, weed residues and careless field management. The strategy of chemical control prevention first, control second was put forth in the present paper, based on the studies. Meanwhile a variaty of chemical control techniques were developed, which promoted large-scale extension of rice- inter-planted wheat growing technique. |
