摘 要 ：氮、磷、钾是水稻生长发育中必需的大量营养元素,水稻生长状况及产量和品质形成都与其有直接或间接关系。如何在高投入集约化生产条件下,提高氮、磷、钾肥利用率是研究的难点和热点。本文简要概述氮、磷、钾在水稻体内的功能及遗传特性,以期为培育氮、磷、钾高效利用水稻品种提供依据。

Abstract:Nitrogen (N), phosphorus (P) and potassium (K) are the essential nutrition elements which play an important role in the process of rice growth and the formation of the yield and quality. How to improve the utilization of N, P and K fertilizer under an intensive rice production system is a hot and difficult issue. This paper reviewed the function and genetic characteristics of the N, P and K in rice, it aims to provide a reference for breeding rice varieties with N, P and K high use efficiency.
