摘要
观察了不同水稻品种对绿磺隆的敏感性，发现“９３２５”、“９－９２”、“９３８０”等３品种对绿黄隆高度敏感。采用添加法试验，证实绿磺隆残留对水稻株高、分蘖、干物质积累、产量影响明显，残留致使“９－９２”水稻减产２．３２％～２３．５８％。建议在镇江市沿江、孟河平原和丘陵非重草害田块，应停止使用绿磺隆或通过复配方式，降低绿磺隆用量。
The sensitivities of different species of paddy rice to chlorsulfuron have been observed.The results show that“9-92”,“9325”and“9380”paddy rice species were highly sensitive to chlorsulfuron residue.Based on the results of adding method,the effects of chlorsulfuron residue on the height,littering,dry matter accumulation and yields of paddy rice are significant.The yield of“9-92”rice decreased by 2.32 %-23.58%.In Yanjiang Plain,Menghe Plain and the hilly areas of Zhenjiang municipality the application of chlorsulfuron should be banned in farmlands with no serious herb problems existing.
