| 摘 要： | 以长期定位试验为平台,研究不同施肥制度下土壤Fe、Mn、Zn、Cu、Pb含量的变化及转化情况。结果表明:施肥对土壤全量微量元素含量没有显著影响,但对元素有效态含量影响显著,施肥导致土壤有效态微量元素含量增加,具体表现为化肥配施循环猪圈肥(NPK+M)处理微量元素有效态最高,单施化肥(NPK)处理次之,循环猪圈肥(M)处理更低,对照(CK)处理最低。各处理土壤微量元素收入均小于支出,不同处理间收支差额NPK+M

| Abstract: | Taking an 18-year field experiment in the lower reach of Liaohe River Plain as a platform,this paper analyzed the dynamic changes of trace elements in aquic brown soil under different fertilization modes.Fertilization had little effects on the concentrations of soil total trace elements,but affected the concentrations of soil available trace elements significantly.Treatment NPK+pig manure (M) had the highest concentrations of soil available trace elements,followed by treatments NPK,M,and CK.In all treatment... |
