土壤稀土元素对太行山区大枣品质影响的探讨

摘要

为了使太行山高品质大枣得到持续发展，从稀土元素在农业地质的应用出发，采用ICP-MS法对河北省太行山大枣主产区土壤的稀土元素含量进行了测定，分析了稀土元素的分布特征；并结合大枣品质测定结果，分析了土壤稀土元素分布及含量特征与大枣品质的相关关系。结果表明：土壤稀土元素含量与大枣品质的相关性达到了显著水平，其中，与大枣可溶性糖和可滴定酸含量呈正相关，与糖酸比和可食率呈负相关。%Studying from the aspect of application of rare earth elements in agricultural geology,the con-tent of rare earth elements in soil of the jujube main producing areas of Hebei Province Taihang Mountain were determined,the distribution characteristics of rare earth elements were analyzed,then combined with the results of jujube quality the relation ship between characteristics and quality of jujube distribution and content of rare earth elements in soil were analyzed.The results showed that the correlation between soil content of rare earth elements and jujube quality reached a significant level,among them,the soluble sug-ar and titratable acid content were positively correlated with soil content of rare earth elements,while the ratio of sugar to acid and edible rate showed a negative correlation with soil content of rare earth elements.
