    Effects of Deer Dung and Microbial Fertilizer on the Bioavailability of Pb and Zn in Vegetable Soil

    • 摘要: 通过盆栽试验,研究了不同添加量鹿粪和微生物菌肥对蔬菜地土壤中重金属Pb和Zn生物有效态含量及小白菜(Brassica campestris)植株Pb和Zn含量的影响。结果表明:添加鹿粪及菌肥均显著降低了土壤中Pb和Zn的有效态含量。w为5%鹿粪添加量和10%菌肥添加量处理组对降低Pb生物有效态效果最好,分别降低25.81%和26.48%(P < 0.05)。添加鹿粪和菌肥促进了酸可提取态、可还原态和可氧化态Pb向残渣态Pb转化。在6个处理组中,小白菜植株中Pb和Zn含量与CK相比均显著降低,5%鹿粪处理对植株中Pb含量降低效果最好,下降48.50%;而10%菌肥处理对植株中Zn含量降低效果最好,下降32.51%。小白菜植株中的Pb和Zn含量与土壤有效态Pb和Zn含量均达极显著相关(P < 0.01)。

       

      Abstract: The influence of different dosage of deer dung and microbial fertilizer on the content of DTPA-Pb and DTPA-Zn in vegetable soil and the content of Pb and Zn in Brassica campestris was studied through the pot experiment. Results show that the addition of deer dung and microbial fertilizer could significantly decrease the contents of DTPA-Pb and DTPA-Zn in vegetable soil. The content of DTPA-Pb was decreased significantly by 25.81% (P < 0.05) with 5% deer dung addition and the content of DTPA-Pb was decreased significantly by 26.48% (P < 0.05) with 10% microbial fertilizer addition. Application of deer dung and microbial fertilizer colud promote the transformation of acid-extractable Pb, reducible Pb and oxidation state of Pb to residual Pb. Compared with the blank experiment, the content of Pb and Zn in the Brassica campestris among the six treatment groups decreased significantly, 5% deer dung treatment group was the most effective on the decrease of the content of Pb in the plant by 48.50%. 10% microbial fertilizer treatment group was most effective on the decrease of the content of Zn in the plant by 32.51%. The content of Pb and Zn in Brassica campestris were most significantly and positively correlated with the content of DTPA-Pb and Zn in soil (P < 0.01).
