【Abstract】 On the basis of analysis and contrast,It was showed that efficiency of phosphorus fertilization was very good butthat of nitrogen fertilizer was limited in the worst drought years,which is completely different from that of generalyears. The unusual property of fertilization effect upon winter wheat closely related to N and P specific physiologycharacteristics and mechanism of N and P absorption.更多还原
