采用实验室盆栽方法模拟小白菜田间施药,设置正交实验探究盐胁迫与复配农药甲维盐·毒死蜱的复合污染对小白菜生理生化效应的影响,包括小白菜的生长状况,叶绿素、还原性糖、可溶性蛋白和纤维素含量的变化。研究结果表明:在盐胁迫和甲维盐·毒死蜱交互作用下,小白菜的生长受到明显抑制,且盐分和甲维盐·毒死蜱浓度越高,抑制程度越大;小白菜叶片中叶绿素、还原性糖、可溶性蛋白质、纤维素的含量随土壤盐分和甲维盐·毒死蜱浓度的增加均有不同程度的变化,与对照组相比,其生理指标均有所降低。运用Duncan′s新复极差法对盐胁迫和甲维盐·毒死蜱作用进行主效应分析,结果表明农药甲维盐·毒死蜱对小白...

The impacts of salt and emamectin benzoate-chlorpyrifos mixture on physiochemical characteristics of non-heading Chinese cab-bage were investigated using orthogonal experimental design and pot culture. Parameters such as chlorophyll, reducing sugar, soluble protein and cellulose of non-heading Chinese cabbage were chosen. Results showed that the physiochemical parameters were inhibited in varying degrees by salt and emamectin benzoate-chlorpyrifos mixture in a dose-effect mode. The values for these parameters decreased with in-creasing levels of contaminants. The main effect by using Duncan's ...
