摘    要:通过对红壤水稻土17年长期定位施肥试验的研究,比较了不同施肥制度下水稻产量及肥料表观利用率、农学利用率、生理利用率之间的差异。结果表明,无论早稻还是晚稻,有机无机肥配施施肥制度(OM)下的水稻产量都最高,相对于CK增产率分别为108.9%、53.8%;其次为节约型有机无机肥配施施肥制度(JF),增产率分别为83.3%、47.8%。对肥料表观利用率、农学利用率、生理利用率的研究可看出,节约型有机无机肥配施施肥制度(JF)和纯化肥施肥制度(NPK)的肥料利用率处于较高水平。综合产量和肥料利用率两因素来看,JF施肥制度更符合现代农业发展需要。

关 键 词:施肥制度    双季稻    产量    肥料利用率

Abstract:This paper compared fertilizer use efficiency among different systems over 17 years in a long-term fertilization field experiment in red paddy soil, rice yield and the apparent recovery efficiency(ARE), agronomic- (AUE), physiological- use efficiency (PUE) of different nutrients were studied. The results showed that, the yields of early and late rice in organic-inorganic fertilizing system (OM) were always the highest, compared to CK, their yields increased 108.9% and 53.8%, respectively. The second is saving-fertilizing system (JF), their yields increased 83.3%、47.8% than in CK respectively, which indicated that, inorganic-organic fertilizing system could significantly promote rice yield in the experimental condition. The studying of ARE, AUE and PUE showed that, fertilizer use efficiency of JF and NPK were greater than other fertilizing systems. Considering the yield and fertilizer use efficiency, it is concluded that, JF is more pronounced in modern agricultural development demand than others.
Keywords:fertilizing system  double-crop rice  yield  fertilizer use efficiency
