分析了不同有机肥料中锌、铜、锰元素的含量，同时研究了有机肥对土壤锌、铜、锰含量的影响。试验证明有机肥料是提供作物锌、铜、锰营养的良好肥源，施用有机肥料可提高土壤锌、铜、锰的含量，但不同施肥处理对土壤锌、铜、锰有效化的影响和作用不同，其中施用有机肥料增加土壤锌、铜有效态含量，并增加土壤全锌、全锰含量。单施化肥除有效态锰增加外，土壤锌、铜、锰各形态含量均减少
The contents of Zn, Cu and Mn in different organic fertilizers were analyzed. The effects of organic fertilizers on Zn, Cu and Mn contents in soils were also studied. The results showed that organic manure was a good source of nutrients for crop zinc, copper and manganese. Application of organic manure could increase the contents of zinc, copper and manganese in soil, but different fertilizers had different effect and effect on the availability of soil zinc, copper and manganese , In which application of organic manure increased soil zinc and copper effective content and increased soil total zinc and total manganese content. Except for available manganese, the contents of Zn, Cu and Mn in soil all decreased
