通过对免耕稻田使用的除草剂农民乐747、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747、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747、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)6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3种除草剂的6个重金属含量均未超标,说明农民乐747、草甘膦、克无踪对稻田环境和稻米生产是安全的。
By monitoring and analyzing the residual amount of herbicide Pei-Le 747, 10% glyphosate and Ke-Qian-No in soil and rice and rice bran used in no-tillage rice fields, the results showed that 1 year 2 years, 2 years 4 years 3, 3 years 6 years, 4 years 5 years 5 years, 10 years, 6 years 12 farmers make use of farm music 747,10% glyphosate, no trace in the soil, rice, rice bran residues were not detected. At the same time, six pesticides, such as Cd, Hg, As, Pb, Cr and Cu, of 747%, 10% glyphosate, The results showed that the contents of six heavy metals in three herbicides did not exceed the standard, indicating that peasants Le 747, glyphosate and Kweichao are safe for paddy field environment and rice production.
