摘要
用ASI法和常规方法对128个紫色土样的微量元素Cu、Zn、Fe、Mn进行提取测定,经简单相关分析得出:ASI法提取的有效Cu、Zn、Fe、Mn与常规方法提取结果均呈极显著相关;而从土壤的酸碱性来看,两种方法在酸性土上对Cu、Zn、Fe、Mn的测定值分别都达到极显著相关,在中性和石灰性土上只有Cu、Fe分别呈极显著相关。小麦盆栽试验结果表明,ASI法与常规方法分析的Cu、Zn、Mn含量与小麦吸收量间都呈显著或极显著的正相关关系,但是ASI法和常规方法分析的Fe含量与小麦对Fe的吸收量均无显著相关关系。
Microelement Cu,Zn,Fe and Mn in 128 purple soil samples were measured by method ASI and conventional methods. Result shows that the correlation of available Cu,Zn,Fe and Mn measured by method ASI was significant with conventional method respectively.In acid soil ,the content of Cu,Zn,Fe and Mn measured by two menthods were correlated markedly; only Cu and Fe were correlative markedly in neutral and calcareous soils. The result of potted plant showed that Cu,Zn and Mn extracted by method ASI were treated as available nutrient credibly. As concerned Fe, correlation between capacity of absorption and content in soil extracted by the two methods was not remarkable.
