摘要: 通过中国农业科学院红壤实验站红壤稻田长期定位试验,分析了无机肥(化肥NPK)与有机肥(M,NPK养分相当)长期施用对双季稻增产潜力的影响。31年的定位试验结果表明:1) 施肥能增加水稻早晚稻稻谷和地上部产量,提高土壤有机碳含量;2) 有机无机肥配施对水稻早晚稻稻谷高产稳产作用最大,同时也最能增加地上部产量,能较快提高土壤有机碳含量;3) 随着试验年份增加,单施有机肥对早晚稻稻谷和地上部的增产效应表现出优于单施化肥的趋势,提高土壤有机碳含量的效果明显优于单施化肥。

Abstract: The yield potential of double cropping rice was investigated after 31year fertilization treatments at the same application rates of nitrogen (N), phosphorus (P), and potassium (K) in the from of in organic manure and chemical fertilizer (NPK)in the Red Soil Field Experimental Station, Chinese Acadamy of Agricultural Sciences, in 2012. Fertilizer application promoted rice yield and total rice aboveground biomass, increased soil organic carbon content, with combined application of organic fertilizer and chemical fertilizer being better. Combined application of organic fertilizer and chemical fertilizer showed a better yieldand aboveground biomasspromoting effect, and application of organic fertilizer has the stepwise larger effect on rice yield and aboveground biomass  and has the obvious larger effect on soil organic carbon content than application of chemical fertilizer.

Key words: longterm experiment, fertilization model, red soil paddy field, yield, organic carbon content
