摘要

该文通过对比分析表明:特大干旱年份

磷肥肥效显著

氮肥肥效受抑。与一般年份截然相反。造成这种异常的原因

与氮、磷的生理特性及吸收机理密切相关。

Abstract

On the basis of analysis and contrast

lt was showed that efficiency of phosphorus fertilization was very good but that of nitrogen fertilizer was limited in the worst drought years

which is completely different from that of general years. The unusual property of fertilization effect upon winter wheat closely related to N and P specific physiology characteristics and mechanism of N and P absorption.
