10年田间定位试验结果表明 ,以无肥 (CK)为对照 ,有机物循环处理 (C)可增产 5 6 .5 %,NPK配合增产6 2 .5 %,有机与无机肥配合增产 80 .7%;施肥实现的水稻产量中由于化肥应用所占的贡献份额为 38.5 %,有机与无机肥配合施用所占的贡献份额为 44 .7%;随着NPK配合程度的提高 ,土壤有机质含量由降低到基本平衡 ,有机与无机肥配合能有效地促进土壤有机质的积累 ;氮、磷和钾进入红壤稻田系统及系统内有机物循环利用 ,可增强土壤氮、磷和钾养分库。 The result of 10-year field experiment showed that CK (CK) could increase yield by 6.56%, NPK increased by 6.52% and organic and inorganic fertilizer increased by 80.7% ; The share of contribution of fertilizers to the application of chemical fertilizers was 38.5% and that of organic and inorganic fertilizers was 44.7%; with the NPK compounding, the content of soil organic matter decreased from With the basic balance, organic and inorganic fertilizers can effectively promote the accumulation of soil organic matter; Nitrogen, phosphorus and potassium into the red soil paddy system and the system of organic matter recycling, can enhance soil nitrogen, phosphorus and potassium nutrient pool.
