摘　　要：通过对免耕稻田使用的除草剂农民乐 74 7、10 %草甘膦、克无踪在土壤和稻米、米糠中的残留量进行监测分析 ,结果表明 ,1年 2造、2年 4造、3年 6造、4年 5造、5年 10造、6年 12造使用农民乐74 7、10 %草甘膦、克无踪在土壤、稻米、米糠中的残留量均未检出。同时对农民乐 74 7、10 %草甘膦、克无踪除草剂本身的镉 (cd)、汞 (Hg)、砷 (As)、铅 (Pb)、铬 (Cr)、铜 (Cu)六个农作物无公害生产主要重金属残留量进行测定分析 ,结果三种除草剂的六个重金属含量均未超标 ,说明农民乐 74 7、草甘膦、克无踪对稻田环境和稻米生产是安全的。An analysis on the monitoring & evaluation of the residues of pesticid es such as No 747 Nongminle, 10 percent of Plyphosate and Kewuzong soil and rice as well as rice bran in free-plowing paddy was conducted. The result indicated that no certain amount of these pesticide residues were tested out respectively on paddy, rice and rice bran for 2 rotate rice of one year, 4 rotates of 2 years , 6 rotates of 3 years, 5 rotates of 4 years, 10 rotates of 5 years ad 12 rotate s of 6 years. The certain amount of residues of the main heavy metals contained in No 747 Nongminle, 10 percent of Plyphosate and Kewuzong, such as Cd, Hg, As, Pb, Cr ad Cu were also tested respectively in the six free-polluted crop product ion bases. The experimental result suggested that the contents of the six heavy metals in the three pesticides didn't excess the standard, thus explained that N o.747 Nongminle, Plyphosate and Kewuzong are safe to paddy environment and rice production.
