分别用丙酮和酸性甲醇提取土壤及花生秧、花生仁中克线磷的残留量。亩施5%克线磷颗粒剂10kg和15kg,土壤中药剂消失半衰期多在1～3周。药剂主要分布在0～15cm土层内。在该层土中,整个花生生长期都可检测到药剂。15～30cm土层内药量少,而且分解较快。收获时,花生秧(晒干)中药剂残留量为0.17～2.15ppm,花生仁(晒干)中残留量低于0.01ppm。实验还发现,克线磷具有从根部向茎叶的单向传导性。
Acetone and acidic methanol were used to extract soil and peanut seedlings, peanut kernel in the amount of residual phosphorus. Mushi 5% grams of phosphorus granules 10kg and 15kg, soil half-life of the disappearance of drugs in the more than 1 to 3 weeks. Pharmacy is mainly distributed in 0 ~ 15cm soil layer. In this layer of soil, pesticides can be detected throughout the peanut growing season. 15 ~ 30cm soil less dose, but also faster decomposition. Harvest, peanut seedlings (dried) in the residual amount of 0.17 ~ 2.15ppm, peanut (dried) residue less than 0.01ppm. It was also found experimentally that cetyl phosphate has unidirectional conductivity from the root to the stem and leaf.
