山东乐陵金丝小枣种植区土壤地球化学特征

Study on the Soil Geochemical Characteristics of Jinsi Jujube Planting Areas in Leling,Shandong

以全国土地现状调查与污染防治项目取得的地球化学资料为依据,通过分析研究乐陵金丝小枣种植区土壤化学元素特征,以及土壤化学元素与乐陵金丝小枣相应元素含量之间的关系,综合得出金丝小枣种植区土壤中K、P、Cu、Fe、Mg、Mn、Se等元素含量较高,且对金丝小枣的品质影响较大。根据相关分析,金丝小枣果实与土壤元素中的P、Zn、B呈显著相关关系,其相关关系分别为0.5971、0.6957和0.5289;与N、Ca呈低度相关性,其相关系数均大于0.3。结合基础调查成果,提出了金丝小枣合理规划建议。

Based on the geochemistry data of present situation land survey and pollution control project,the geochemical characteristics of soils in Jinsi jujube planting areas of Leling were studied,and correlation analysis was performed between elements in soil and jujube samples.The results indicated that the contents of K,P,Cu,Fe,Mg,Mn,Se,etc.in soils were high in Leling planting areas,which affect the quality of Jinsi jujube significantly.The correlation analysis illustrated that P,Zn and B in jujube samples were significantly correlated with those elements in soil samples,the correlation coefficients are 0.5971,0.6957 and 0.5289,respectively;the correlation coefficients of N and Ca were lower,but higher than 0.3.Based on the results of the study,suggestions were also provided for Jinsi jujube planting.
