应用甲胺磷农药对土壤动物进行污染模拟实验．结果表明，甲胺磷农药对土壤动物有明显影响，并随着甲胺磷溶液处理浓度的增加，土壤动物的种类和数量显著减少；多样性指数，高处理浓度（０．５４ｍｌ／Ｌ）时为３．７５９６，低处理浓度（０．０１ｍｌ／Ｌ）时为５．７９６２，对照组则为８．５７１４．大型土壤动物蚯蚓的染毒实验表明，甲胺磷对蚯蚓有明显的致死作用，其半致死浓度（ＬＣ５０），２４ｈ为１３．７ｍｌ／Ｌ，４８ｈ为５．４ｍｌ／Ｌ，７２ｈ为３．９ｍｌ／Ｌ，计算所得蚯蚓生活的安全浓度为０．２５１７ｍｌ／Ｌ．
Application of methamidophos pesticide on soil animal pollution simulation experiment. The results showed that methamidophos pesticide had a significant effect on soil animals, and with the increase of methamidophos solution, the species and quantity of soil animals decreased significantly. When the diversity index and the high concentration (0.54ml / L) 3.7596 for the low-treatment concentration (0.01 ml / L) and 8.5714 for the control group. The results showed that methamidophos had a lethal effect on earthworms. The LC50 was 13.7ml / L for 24h, 5.4ml / L for 48h, 3.9ml for 72h / L, calculated the safe concentration of earthworms life 0.2517ml / L.
