摘要
对节节麦在山西冬麦田的初发时间、分布、为害情况及防除措施进行了调查分析,结合研究工作的开展,针对性地提出了新的防除技术对策。调查发现,节节麦在山西冬麦田最早出现为害的时间是2001年,截止目前,全省节节麦的发生面积已超过6000hm2;节节麦在山西主要分布在运城、临汾的平川麦田,晋城城区和泽州一带也有零星发生;节节麦为害小麦,一般造成小麦产量损失5%～8%,个别严重地块甚至毁种绝收。现有的防除技术成本高,效果差;采用播前种子处理、深翻压草、适时拔除及科学化防等技术措施,可有效解决节节麦防除难的问题。
This study was conducted to investigate and analyze the incipient time, distribution, damage situation and implementation situation of measures against Aegilops Squarrosa in winter wheat fields in Shanxi province. Based on the implementation of the research work, the new agricultural control measures against Aegilops Squarrosa was Put forth. The survey showed that the first threat of Aegilops Squarrosa in winter wheat fields was happen in 2001 in Shanxi province. Up to the present, the infested areas are expanding over 6 000 hm^2. Aegilops Squarrosa was mainly distributed in the plain of wheat fields in Yuncheng and Linfen, but also a number of small sporadic distribution in Jincheng and Zezhou. Aegilops Squarrosa is an alien invasive weed and can reduce approximately the crop yield by 5%～8%, even some invaded place will harvest nothing. The present control method is of high cost and poor target. The measures of seed treatments before sowing,deep tillage to restrain weeds,weeding in due time and scientific chemical control can solve this tough problem of Aegilops Squarrosa effectively.
