为研究草铵膦在油菜植株、土壤中的消解情况及其残留对下茬作物水稻的影响,本研究采用超高效液相色谱-质谱联用技术,研究了转基因和非转基因油菜施用灭生性除草剂草铵膦后叶片和土壤中草铵膦的消解动态及对后茬作物水稻生长发育的影响。结果表明:苗期施用1%草铵膦,转基因和非转基因油菜叶片中的半衰期分别为5.3 d和3 d,喷药后21 d,转基因油菜叶片中测不出草铵膦存在;在田间条件下夏季土壤和秋季土壤中草铵膦的半衰期分别为2.5 d和6.6 d,夏季土壤和秋季土壤分别在中第14天和第28天检测不到草铵膦;室内恒温4℃和25℃情况下,草铵膦降解速率较田间环境中缓慢,半衰期分别为21 d和14.4 d。水稻播种前1...

In order to study the dissipation of glufosinate in rape plant and soil and the effect of its residue on next-season rice, UPLC-MS/MS technology was used to study the dissipation of glufosinate in leaves and soil of transgenic and non-transgenic oilseed rape after being used with exogenous herbicide glufosinate as well as the impact on the growth and development of next-season crop rice. The results showed that treated with 1% glufosinate in seedling stage, half-lives in the leaves of transgenic and non-transgenic oilseed rape were 5.3 d and 3 ...
