    摘要:

    为了解施肥对山东寿光市设施蔬菜土壤重金属输入的影响,采用随机取样的方法在寿光市收集了10个氮磷钾三元复混肥和21个鸡粪肥样品,测定了肥料中重金属Cu、Zn、Cd、Pb的含量。结果表明:鸡粪肥中Cu、Zn、Cd、Pb含量高于氮磷钾三元复混肥,但与中国有机无机复混肥标准(GB18877—2002)相比,鸡粪肥中Cd未超标;2种类型肥料中的Pb均处于较低水平;每年通过施肥输入寿光设施蔬菜土壤的Cu、Zn、Cd、Pb量分别为3 516.282、23 731.500、19.473和69.011 g/hm2,其中鸡粪肥输入的量占肥料总输入量的79%~97%。

    Abstract:

    The concentrations of Cu, Zn, Cd and Pb of NPK compound fertilizer (10 samples) and chick manure (21 samples) were measured for heavy metals accumulation by application of chemical fertilizer and manure in vegetable greenhouse soil in Shouguang. The results showed that contents of Cu, Zn, Cd and Pb in NPK compound fertilizer were lower than that in chicken manure, while the content of Cd in chicken manure was under the limitation (GB18877 2002). Pb content was low in both the compound fertilizer and the chicken manure. The inputs of Cu, Zn, Cd, and Pb to the greenhouse vegetable soil through fertilization every year in Shouguang were 3 516.282, 23 731.500, 19.473 and 69.011 g /ha respectively, and chicken manure accounted for 79%97% of the total fertilizer applied.
