摘　　要：氢氧化钙作为土壤钝化剂施用能够有效地降低土壤中重金属镉的生物有效性[1]。本文选取被重金属镉污染过的土壤在单独施加氢氧化钙之后,随着时间的推移其中有效镉的含量,通过四组试验数据和空白组的对比,分析不同时期氢氧化钙的作用效果,从而选择合适的施用周期[2]。Application of calcium hydroxide as a soil passivator can effectively reduce the bioavailability of heavy metal cadmium in the soil[1].This paper selects the soil contaminated by heavy metal cadmium after applying calcium hydroxide alone,and over time the effective cadmium content in it,through the comparison of four sets of experimental data and the blank group,analyzes the effect of calcium hydroxide in different periods.So choose the appropriate application cycle[2].
