摘　　要：本文采用DTPA浸提处理土样,原子吸收法直接进样测定,并就影响准确度的控制因素进行分析.结果表明,本法快捷、简便、准确;同时指出黑龙江省土壤整体上锌供应不足.This paper describes a method for determination of available zinc in soil using DTPA for dipping and using AAS for the result. Controllable factors which affect accuracy are analyzed. The results show that the procedure is convenient, rapid, accurate, and the contents of available zinc in soil arc not enough for providing on the whole in Heilongjiang Province.
