通过自制根箱试验，研究了植物根际土壤酶活性（脲酶，转化酶，酸性磷酸酶，碱性磷酸酶）和微生物区系（细菌、真菌、放线菌）在不同蕹菜品种中（ Cd－PSC，non-Cd-PSC）镉积累行为的特征。结果表明：蕹菜茎叶的镉积累特性具有稳定性。相同条件下，根际土壤的4种酶活性和3类微生物数量都显著大于非根际土壤。在蕹菜两个品种间，3类微生物的数量差异显著，其大小排序为：细菌，真菌，放线菌；转化酶、酸性磷酸酶、碱性磷酸酶在品种间差异极显著，其大小排序为：酸性磷酸酶，转化酶，碱性磷酸酶；脲酶在品种间的差异性不显著。

A root box experiment was conducted to study the characteristics of four kinds of rhizosphere soil enzymes (urease, invertase, and acid and alkaline phosphatases ) and three kinds of microflora (bacteria, fungi, and actinomyces ) in cadmium accumulation of different species of Ipomoea aquatica Forsk.( Cd-PSC, non-Cd-PSC) .The results show that the cadmium accumulation in the stems of leaves of Ipomoea aquatica Forsk.was stable .Under the same conditions , the enzymatic activities and the microorganism amounts were significantly greater in the rhizosphere soil than in the non-rhizosphere soil . There were significant differences in the microorganism amount between the two species of Ipomoea aquatica Forsk., showing a descending order in amount , as follows:bacteria, fungi, and actinomycetes.Significant differences existed in the species of invertase , and in acid and alkaline phosphatases , showing a descending order in amount as follows:acid phosphatase , invertase , and alkaline phosphatase .No significant differences were found in the species of ureases .
