| 摘要: |
| 为探讨丛枝菌根真菌AMF(Arbuscular Mycorrhizal Fungi)对土壤及水稻植物中三环唑农药的残留消解效果,测定不同菌剂施用及不同质量分数三环唑施加后水稻土壤及植物中三环唑残留量．结果表明:施加菌剂后的处理侵染率极显著提高,其中混合菌剂(GM+GI)对水稻的侵染效果(侵染率56.06％)最佳,优于摩西球囊霉(GM侵染率53.86％)和根内球囊霉(GI侵染率34.57％)．施加菌剂的处理三环唑的消解速率均大于CK（对照）,半衰期均低于CK,土壤中3种菌剂处理对三环唑的消解效果由大到小为GM+GI> GM> GI,4种不同质量分数下菌剂在150％施药情况下可以发挥最好效果,植物中3种菌剂处理对三环唑的消解效果由大到小为GM> GM+GI> GI,GM和GM+GI在150％施药情况下可以发挥最好效果． |

| Abstract: |
| To explore the degradation effects of AMF on the residual of tricyclazole in the soil and plant of rice, we assay the residual quantity of tricyclazole in soil and plant of rice which were set by different AMF and different concentration. The results showed that the infection rate was significantly increased after applying agent. The infection rate of GI+GM was 56.06％, which was better than that of GM with 53.86％ and GI with 34.57％. The digestion rate of tricyclazole of those treatments with AMF was bigger than that without AMF. The half-life period of tricyclazole of those treatments with AMF were shorter than that without AMF. The digestion effect of three AMF on tricyclazole in soil was GM+GI> GM> GI. AMF got the best effect at 150％ which was the one of four different concentrations. The digestion effect of three AMF on tricyclazole in plant was GM> GM+GI> GI, GM and GM+GI got the best effect at 150％. |
