绿磺隆在小麦及土壤中的残留动态研究

Study on the Residues of Chlorsulfuron in Wheat and Soil

研究了绿磺隆在江苏吴县和石家庄土壤和植株中的残留动态及其作物收获时在土壤和小麦籽粒中的最终残留，结果表明：绿磺隆在植株上的降解较快．收获时，它在小麦籽粒中均未检出；绿磺隆土壤残留两地差异较大．降解半衰期在石家庄土坡为32．9天，在江苏吴县为22．8天，由于绿磺隆对下茬一些作物极为敏感．对绿磺隆土壤残留问题应引起高度重视。

The degradation of chlorsulfuron in wheat and soils was studied. The results showed that the dE Gradation of chlorsulfuron in wheat was very quickly, the last residue at harvest was less than detectable level. The degradaction halflive in soils were respectively 32. 9 days in Shijiazhuang City and 22. 8 days in Wuxian, Jiangsu Province. Many plants are very sensitive to chlorsulfuron. it can cause plant harm because chlorsulfuron residue in soils.
