摘    要:通过系统整理分析60年来广东省在水稻肥料利用率上的研究文献,结果表明,广东省氮、磷、钾肥利用率的均值分别为32.56%、23.17%和44.46%,随着施肥量的增加,氮、磷、钾的肥料利用率呈下降趋势。其中氮肥和磷肥利用率在1949—1980年、1980—2000年和2000—2010年3个阶段均呈"高—低—高"趋势变化,但钾肥利用率1980—2000年间为47.69%,高于2000—2010年的39.98%。不同施肥技术下氮肥利用率差异较大,控释肥技术为47.20%,配方施肥技术为36.65%,常规施肥技术为26.18%,从产量和肥料利用率层面来考虑,控释肥技术是目前最优的施肥技术。

Abstract:The results of fertilizer use efficiency during the past 60 years were systematically settled and analyzed.The results showed that: in Guangdong Province,the averages fertilizer utilization of nitrogen(N),phosphorus(P) and potassium(K) were 32.56%,23.17% and 44.46%,respectively.The fertilizer utilization about nitrogen(N),phosphorus(P) and potassium(K) was respectively decreased with the increase of the amount of fertilizer application.The utilization of N and P fertilizer showed a tendency of high-low-high in three stages from 1949 to 1980,1980 to 2000,and 2000 to 2010 years.However,the utilization of K fertilizer from 1980 to 2000(47.69%) was higher than that from 2000 to 2010(39.98%).In addition,the nitrogen use efficiency(NUE) of different fertilization technologies was different.The NUE of controlled release fertilizer technology,soil testing and formulated fertilization and conventional fertilization were 47.20%,36.65% and 26.18%,respectively.Taking yield and fertilizer use efficiency into account,controlled release fertilizer technology is the optimal technology at present.
Keywords:fertilizer use efficiency  apply fertilizer  Guangdong province  rice
