| 摘 要： | 为探讨大田施用有机肥对小麦吸收重金属汞和铅的影响,通过大田小区试验,研究了不同有机肥施用量对土壤有效态汞、铅以及小麦吸收的影响。结果表明,土壤有效态汞、铅含量的高低受有机肥施用量的影响明显,继而影响小麦对土壤汞、铅的吸收;土壤有效态汞、铅的含量及小麦吸收汞、铅量均与施用有机肥呈显著负相关性,土壤有效态汞、铅的含量及小麦吸收汞、铅量之间呈显著正相关性。说明,施用有机肥可抑制小麦吸收土壤中的汞和铅。 |

| Abstract: | Effect of application amount of organic fertilizer on available mercury(Hg),lead(Pb) in soil and their adsorption of wheat were studied in plot experiment.The results showed that the amount of available Hg,Pb in soil was obviously affected by application amount of organic fertilizer,and affected the absorption of wheat afterwards.Content of available Hg,Pb and their absorption amount in wheat had significantly negative correlation with application amount of organic fertilizer,while available Hg and Pb had s... |
