摘　　要：以湖南省重金属污染耕地修复综合治理试点区中标土壤调理剂产品和复合微生物肥产品为试材,在长沙县和湘乡市典型稻区开展田间试验,研究土壤调理剂、复合微生物肥对农田土壤和水稻中镉、铅含量的影响。结果表明:施用土壤调理剂能明显提高土壤的pH值,复合微生物肥对土壤的pH值无明显影响;施用土壤调理剂和复合微生物肥均能降低土壤有效镉含量及稻米和稻草中总镉、总铅含量,但土壤调理剂的降低效果要明显优于复合微生物肥,二者对土壤总镉、总铅含量没有明显的影响。Took the soil conditioner products and compound microbial fertilizer products to heavy metal pollution in Hunan Province farmland restoration comprehensive management pilot areas as test materials, field experiments were conducted in a typical area of Changsha County and Xiangxiang City, the research on the influence of soil conditioner, compound microbial fertilizer on Cd, Pb of soil and rice. The results showed that the application of soil conditioner significantly increased the pH value of soil, and the compound microbial fertilizer had no significant effect on the pH value of soil; the application of soil conditioner and compound microbial fertilizer decreased the content of available cadmium in soil and the contents of total cadmium and total lead in rice and straw, however, the effect of soil conditioner was significantly lower than that of compound microbial fertilizer, and the two had no significant effect on total cadmium and total lead content.
