摘要：

利用开始于1982年的湖南祁阳官山坪水稻长期(1982-2010年)定位试验,研究不同施肥条件下水稻产量及土壤有机质、氮素养分的动态变化特征,试验设置NPK、NPKM(M为牛粪)、 NPM、NKM、PKM、M和CK等7个处理.28年长期不同施肥处理结果表明:肥料的施用均能提高土壤有机质、全氮、碱解氮含量和水稻产量.氮、磷、钾化肥+有机肥(NPKM)处理的水稻产量一直保持最高水平,氮、磷、钾化肥(NPK)处理随着试验年限的延长呈下降趋势,其水稻产量逐渐低于其他施肥处理.单施有机肥或有机无机肥配施各处理土壤有机质含量在试验开始后的前16年有一个快速增加的过程,之后略有下降,然后仍保持增长趋势;NPK化肥处理土壤有机质...

摘要(英文)：

A long-term (1982-2010) field experiment was conducted in the Red Soil Experiment Station of Chinese Academy of Agricultural Sciences in Qiyang County of Hunan Province, South-central China to investigate the dynamic changes of rice yield and soil organic matter (OM) and nitrogen contents under different fertilization treatments. The treatments included NPK, NPKM (M: manure), NPM, NKM, PKM, M, and CK. Fertilization increased the soil OM, total N, and alkaline-hydrolysable N contents and the rice yield. In treatment NPKM, the rice yield across the 28 years maintained at the highest level; while...
