结果表明，与常规施氮量处理相比，节水灌溉条件下节肥施氮量处理的氮肥损失率降低，氮肥当季利用率和土壤残留率提高；基施氮肥的利用率高于追施氮肥；土壤肥料氮的残留率在 2 9%～ 41 %之间，分布于 1m土层中，其中60 %以上集中在 0～ 2 0cm土层；在整个小麦生长季内，肥料氮并没有淋洗到 1 30m以下。节肥施氮量在常规灌溉下的当季利用率比在节水灌溉下降低 1 6 6%。

Objective: In this parper, we studied the key problems of resolution and determination,which haven,t been solved by HPLC in Cordyceps sinensis.,such as chromatography condition and extraction condition. Using the condition we studied out, we analysed the nucleosides in Cordyceps sinensis . and in its adulterations and counterfeits by HPLC. The purpose is to find the difference between Cordyceps sinensis . and its adulterations, and also to provide a effective method for quality assess of Cordyceps sinensis .
