| 摘 要： | 介绍了10种农药在14种作物上的消解动态,结果表明,不同类型农药的消解速度是有差异的。其消解速度,有机磷>拟除虫菊酯>有机氯,百菌清与DDT相近。同一农药在不同作物上的消解速度也有明显差异,主要与作物比表面积、生长系数等因素有关。农药在设施作物上的消解速度较露地作物缓慢,且残留浓度呈先上升后下降的动态变化。农药在贮藏作物上的消解速度相当慢,这与其特殊的环境条件有关。

| Abstract: | The degradation trends of ten kinds of pesticide in fourteen species of crops were recommended. The degradation speed were differed obviously from various types of pesticide, such as: organophosphorus > pseudopyrethrins>organochlorine, and chlorothalonil was similar to DDT. The degradation speed of same pesticide was also differed from various species of crops obviously due to the comparative surface area of crops growth factor etc. The degradation speed of crops above the ground was slower than under the ground, and the residual concentration showed that the dynamic changes as increasing first and then decreasing. |
