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。

摘  要:
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 wasM>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.
