摘要
作者采用气相色谱法研究了恶草酮在花生及土壤中的残留规律.结果表明,恶草酮在土壤中的消解过程符合负指数函数递减规律方程 Q=C_0e^(-kT), 半衰期为30—40天;恶草酮在花生茎叶中的残留分布有一个明显的吸收—降解过程.
The residues of oxadiazon on the peanut and soil have deen investigated with GC . The results showed that the dispersion of oxadiazon in soil fitted in index equation ( C=C0e-KT) , the half-life was about 30-40days. There is an apparant process of uptake and dispersion for redue ofoxadiazon in peanut straw.
