| 英文摘要 | To reduce Cd phytoavailability in calcareous soils, the effects of soil amendments ed mud, rape straw, and corn s combination with zinc fertilization on Cd extractability and phytoavailability to spinach, tomato, Chinese cabbage and dish were investigated in a calcareous soil with added Cd at 1.5 mg kg(-1). The results showed that water soluble and exchangeable Cd in soils was significantly decreased by the amendments themselves from 26% to 70%, which resulted in arked decrease by approximately from 34% to 77% in Cd concentration in vegetables. The amendments plus Zn lization further decreased the Cd concentration in vegetables. Also cruciferous rape straw was more effective than ramineous corn straw. In all treatments, rape straw piLls red mLld combined with Zn fertilization was most effective in decreasing Cd phytoavailabill y in soils and it is potential to be an efficient and cost-effective measure to ensure food safety or vegetable production in mildly Cd-contaminated calcareous sods |
