摘要

坡地氮磷流失是洞庭湖农业面源污染的重要来源。以湖南省湘阴县红壤坡耕地土壤为研究对象

通过田间小区试验

探讨玉米减量施肥对产量、化肥利用率和氮磷流失量的影响。结果表明

NP常规施肥量在减少20%范围内对玉米产量没有十分显著的影响

但达到30%时玉米表现减产。减量施肥不仅一定程度提高NP化肥肥效和肥料利用率

而且降低土壤NP流失量。氮的径流量减少了12.54%～28.68%

磷减少了1.3%～30.1%。在各种减量施肥处理中

以控释肥减氮处理效果最佳

有效减少农业面源污染。

Abstract

The loss of nitrogen and phosphorus in sloping land is an important source of Agricultural non-point source pollution.In this research

the sloping red soil in Xiangyin county

Hunan Province was studied through a field experiment in order to discuss the effect of reducing fertilization on maize yield

the utilization ratio of fertilizer and the loss of N

P.The results showed that N

P fertilizer fluctuating within 20% of the conventional wuold not influnce maize yield very significantly.However

when fertilizer...
