中文摘要：

采用一株解磷成团肠杆菌ID-a修复陕北某工业园区长柄扁桃种植地土壤,评价了该地区土壤重金属的污染状况,分析了修复前后土壤中重金属元素Cu,Pb,Zn,Cd存在形态的变化以及解磷菌修复对长柄扁桃叶子及果实中重金属Cu,Pb,Zn,Cd的质量分数的影响。由结果可知：工业园区土壤与未污染的对照组相比Pb,Cd,Cu和Zn质量分数分别增加了24.92,4.45,18.13,77.99 mg/kg;解磷菌修复组与对照组相比土壤中可交换态Cd,Pb,Cu的质量分数显著降低,其相应的残渣态的质量分数增加。长柄扁桃叶子中Pb,Cd和Zn质量分数分别降低了95.14%,40.63%和43.87%,果实中Cu,Zn质量分数分别降低了54.06%和35.91%,长柄扁桃果实中未检测出重金属Pb和Cd。因此,该菌剂能够修复该污染区种植地土壤,提高长柄扁桃的安全性。

英文摘要：

The enterobacter agglomerans ID-a was used to repair the Shaanxi amygdalus pedunculata pall planting soil. The assessment of heavy metals pollution was made. The change of existential state of heavy metals（ Cu,Pb,Zn,Cd） in reconditioned soil and the influence of the heavy metal contents in amygdalus pedunculata pall leaves and fruits were analyzed. Comparing with the uncontaminated soil,the data showed that the mass fractions of Pb,Cd and Cu in the industrial zone increased by 24. 92,4. 45,18. 13 and 77. 99 mg/kg respectively. The remediation by phosphate-solubilizing bacteria can significantly reduce soil exchangeable Cd,Pb,Cu,Zn mass fraction and increase residual Cd, Pb, Cu, Zn mass fraction. Comparing with the non-antibacterial control group, the amygdalus leaves of Pb,Cd,Zn content were reduced by 95. 14%,40. 63% and 43. 87%. The heavy metals Pb and Cd in amygdalus pedunculata pall fruits were never tested and the contents of Cu and Zn decreased by 54. 06%and 35. 91%,respectively. Thus,the inoculation with ID-a strain can not only effectively remediate the polluted soil,but also provide a scientific basis for improving the safety of amygdalus pedunculata pall.
