摘  要：
采用单道扫描等离子发射光谱仪(ICP-AES)对四川北部25个产茶县133个茶园土壤中A l、S、P、K等16种无机营养元素含量进行测定,着重研究了该地区茶园土壤的无机营养元素背景值特征。结果表明,川北茶区土壤中S、P、K、Ca、Ti元素表现为显著贫化,Sb和Se表现为相对富集,其浓集系数k分别达9.47和5.38,其它A l、Mg、Mn等9种元素与中国土壤含量背景值相当或略低;营养元素背景值因土壤类型的不同而表现出一定的差异,Sb、Zn的背景值在不同类型土壤中差异显著,S、Sb的背景值以砂土中最高,K、Mg、Ca、Se、Ti的背景值以酸性紫色土中最高,A l和Mo的背景值以黄壤中最高,而P、Mn、V、B、Zn、Co、N i等元素的背景值则以棕壤中最高。

摘  要：
By using the ICP-AES,the content of 16 kinds of inorganic nutritive elements were mensurated for the soils of 133 tea gardens in 25 counties or sections in the north of Sichuan Province,the characters of the background value of nutritive elements were emphasized.The result showed that the contents of S,P,K,Ca and Ti were all inadequate evidently.Sb and Se were enrichment relatively,the coefficients of enrichment were 9.47 and 5.38 respectively.The content of other elements such as Al,Mg,Mn were corresponded to the background of soil in China.The background value of nutritive elements changed in the different soils.Sb and Zn were significant differently for the different soils.The content of S and Sb were high in the gritstone soil,K,Mg,Ca,Se,Ti were high in the acidic purple soil,the Al and Mo were high in the yellow soil,and the P,Mn,V,B,Zn,Co and N were high in the brown soil,respectively.
