摘　　要：以沾化的马武（M）、古城（G）和冬枣研究所（Y）3个冬枣栽培区0-30 cm土层土壤为研究对象,测定了土壤全氮、全磷、全钾和有机质的含量,分析了土壤剖面和各栽培区各元素的分布情况。结果表明,在0-30 cm土壤剖面中土壤全氮、全磷含量分布规律为0-10 cm〉10-20 cm〉20-30 cm,全钾含量则为10-20 cm〉0-10 cm〉20-30 cm,土壤有机质含量分布规律为0-10 cm〈10-20 cm〈20-30 cm;不同样地之间,土壤全氮、全磷含量为Y〉M〉G〉CK（空地对照）,土壤全钾含量为M〉Y〉G〉CK,土壤有机质含量为M〉CK〉Y〉G。综合分析3个样地土壤氮、磷、钾含量,以冬枣研究所土壤营养条件最好。The study on the contents and their distribution rules of soil N,P and K element and the organic matter in the 0～30cm soil profile from Mawu（M）,Gucheng（G） and Institute of Zhanhua Dongzao（Y） indicated that total N and P distribution rules in soil were 0～10 cm〉10～20 cm〉20～30 cm,and total K distribution rule was 10～20 cm〉0～10 cm〉20～30 cm,and the organic matter distribution rule was 0～10 cm〈10～20 cm〈20～30 cm.In the three sample plots,total N and P content in soil was Y〉M〉G〉CK,total K content was M〉Y〉G〉CK,the organic matter content was M 〉CK 〉 Y 〉 G. The generalized analysis of N, P and K content in soil from three sample plots showed that Institute＇s soil nutritional condition was the best of the three plots.
