| 摘 要： | 通过对湖北省涝渍地开发工程技术研究中心高场示范围场油菜田的田间杂草进行调查，发现涝渍地油菜田杂草的发生特点与非涝渍地存在明显的区别：在涝渍地区域，棒头草等禾本科杂草生长旺盛，为最优势种群；在非涝渍地田块中，禾本科杂草则几乎没有生长，田问杂草单位面积鲜重也大大降低。通过筛选几种化学除草剂，建立了以乙草胺乳油土壤处理或精禾草克与高特克桶混茎叶喷雾为较优方案的杂草防治措施。

| Abstract: | The survey of weed in rape field was conducted in Gaochang experimental farm of Hubei Provincial Engineering Exploitation and Technological Research Center for Water-logging and Watery Cropland.It is found that there were obvious differences between the weeds characteristics in rape field in Water-logging land and in non-water-logging land:the graminaceous weeds such as Polypogon fagax and Alopecurus aequatis,the main species,grew abundantly in waterlogged land;and in non-waterlogged land,Lapsana apogonoides is dominant.Field trials showed that Acetochlor(treated to soil)and the mixture of Benazolin-ethyi+Quizalofop-ethyl(treated to the leaves and stems)are more effective to control the weeds. |
