摘要
通过模拟自然土壤条件,比较不同土壤类型、粒度与含水量对太阳光降解百草枯的影响。结果表明,百草枯在花岗岩砖红壤中比在玄武岩砖红壤中易被太阳光降解。同时,得出了在同一土壤类型不同粒度大小、不同土壤含水量下将得出太阳光降解百草枯后残留量的变化趋势。
By simulating natural soil condition, artificial influence of paraquat amounts, soil granularity, soil moisture and soil temperature on paraquat degradation caused by sunlight were studied. Residual amount of paraquat after degradation was analyzed. Effect of different soil type, soil granularity and soil moisture on paraquat degradation was compared. Simulated experiment indicated that paraquat degradation in granite brick red earth was easier than that in basalt brick red earth. Residual amount of paraquat after sunlight degradation changed significantly in different soil granularity and moisture of the same soil type.
