摘要
氮磷是造成水体富营养化的两个主要元素。国内对氮肥的利用率已进行了大量研究,而对主要作物对磷肥的利用率研究相对较少。本文综述了不同作物的磷肥当季利用率和磷肥的累积利用率、影响磷肥利用率的因素、施用磷肥对作物磷素吸收的影响,施用磷肥对土壤磷素平衡的影响以及施用磷肥对作物产量的影响。建议选择适合当地的磷肥种类、适宜的磷肥用量,轮作中合理分配磷肥、合理灌溉。
Nitrogen and phosphorus are the two chief elements which caused eutrophication in water body.A lot of researches have been conducted on nitrogen fertilizer recovery rate,fewer work was done on phosphorus recovery rate in main crops.This article reviews the following aspects：（1）Phosphate recovery rate in one cropping season and cumulative recovery rate of phosphate in different crops;（2）Some factors influencing phosphate recovery rate;（3）Effect of phosphate application on phosphorus absorption by crop;（4）Effect of phosphate application on phosphorus balance in soil;and （5）Effect of phosphate application on crop yield.
