东北黑土区部分地域除草剂在不同作物类型土壤中残留及分布特征OA北大核心CSTPCD
Herbicide residues and distribution in cropland soils from the black soil region of northeast China
为了解并掌握东北部分黑土区农田土壤除草剂残留情况,本研究调查了东北黑土区6个地区170份土壤样本,共检出17种除草剂.总体来看,乙草胺检出率最高,为74.7%,氟磺胺草醚平均残留量最高,为198.88 μg·kg-1.从省份来看,辽宁省除草剂检出种类最为丰富,黑龙江省除草剂残留量最高.其中,铁岭市、阜新市与长春市、四平市旱田除草剂残留情况更为相似,绥化市土壤除草剂残留情况与前者差异较大.从作物类型来看,水稻田土壤除草剂检出种类更多,旱田作物除草剂…查看全部>>
To investigate herbicide residues in cropland from the black soil regions of northeast China,170 soil samples from six typical black soil regions were collected,and 17 herbicides were detected.In general,acetochlor had the highest detection rate(74.7%),and fomesafen had the highest residual concentration(198.88 μg·kg-1).In terms of regions,soil in the Liaoning Province had the most number of herbicides residue types,and soil in the Heilongjiang Provinc…查看全部>>
