摘要： 为了探索出一套适合河北省土壤养分快速测定的方法，本研究对河北省典型土壤类型土壤样品进行了改进的测定方法与常规方法测定硝态氮结果的相关性分析，同时比较了土壤养分状况系统研究法（ASI）与常规方法测定土壤有效P，K，Cu，Fe，Mn，Zn结果的相关性，结果表明改进方法测定的硝态氮、ASI法测定的土壤有效P，K，Cu，Fe，Mn，Zn与我国常规化学方法测定值呈显著正相关。

Abstract: Analysis of relation between the NO3-_N values got by the conventional method and improved method for the typical soil samples of Hebei Province was introduced in this paper.Also introduced the relations between the soil available P,K,Cu,Fe,Mn,Zn contents determined by ASI method and conventional methods.The results showed that the NO3-_N values got by the conventional method was very significantly related with the value determined by the improved method.the soil available P,K,Cu,Fe,Mn,Zn contents determined by ASI method was also very significantly related with the values determined by the conventional methods.
