Abstract:
The phospholipid fatty acid content method and physical and chemical properties method，together with two kinds of treatment，clean water and clean water+Cd,were employed to analyze the rhizosphere soil of the test potted cabbage,radish and pepper,the effects of different treatments on soil microbial community were studied. The resules showed that there was no significant difference in the content of three kinds of vegetables rhizosphere microbial on soil by water+Cd,but the content of radish rhizosphere microbial on soil less than cabbage and pepper.PCA showed that the treatment of three kinds of vegetables with water+Cd irrigation had the greatest effect on the microbial community structure of radish rhizosphere soil.The contents of PLFA in the rhizosphere microbial community on soil under different irrigation treatments were G+>G->actinomycetes>fungi.Compared with water treatment,there was no significant difference in the value of PLFA in three vegetables treated with water+Cd.Irrigation of vegetables with different irrigation methods,analysis of soil physical and chemical properties during the harvest of vegetables showed that have a greater impact of water+Cd treatment on the cabbage absorbs total nitrogen in the soil,radish and pepper absorb nitrate nitrogen in soil.
