摘　　要：为筛选出生态与经济效益最优的施肥配比,开展了长期定位试验,研究了全化肥、低量和高量化肥配施有机肥、习惯施肥、缺氮和缺磷化肥配施处理红壤区双季稻田氮磷平衡,并评价了各处理生态与经济效益。结果表明,除不施肥对照外,各处理年均氮平衡均为盈余状态;除不施肥对照和不施磷处理外,各处理磷素为盈余状态。习惯施肥、不施磷、不施钾处理施肥配比的氮素盈余量较高,60%有机肥配施化肥、习惯施肥和不施钾处理施肥配比的磷素盈余量较高。30%有机肥配施化肥处理的生态与经济综合评价值最高,能够在确保经济效益的同时兼顾生态效益。In order to screen the optimal fertilization ratio of ecological economic benefits,long-term located experiment was carried out in double cropping rice field of red soil area under the treatments of complete chemical fertilizer,a small and large amount of chemical fertilizer combined with organic fertilizer,customary fertilization,combination of nitrogen deficiency and potassium deficiency.The nitrogen and phosphorus balance was studied,and the ecological economic benefit was evaluated.The results showed that except for CK,the average annual nitrogen balance of each treatment was surplus.Except for CK and non-phosphorus treatment,the phosphorus of all treatments was surplus.The nitrogen surplus was higher in treatments of customary fertilization,non-phosphorus and non-potassium.The phosphorus surplus was higher in treatments of 60%organic fertilizer,customary fertilization and non-potassium.The comprehensive evaluation score of 30%organic fertilizer treatment was the highest,which could ensure economic benefits while taking into account ecological benefits.
