摘　　要：通过田间小区试验研究了施用有机复合肥料对水稻产量和经济效益的影响。结果表明:与常规施肥比较,有机复合肥在氮素投入降低25%的条件下,水稻产量不但没有降低,反而有增产,幅度在11.27%～19.75%,铁杆复合肥+多维肥精处理的水稻产量和氮肥农学利用效率最高。经济效益分析表明,有机复合肥各增收幅度在2 985～5 325元/hm2之间。以铁杆复合肥+多维肥精的处理增收幅度最高,达到5 325元/hm2。A field plots experiment was conducted to study the effects of compound fertilizer on rice yield and economic benefits. The results showed that compared with the conventional fertilization treatment, with the organic compound fertilizer under the condition of nitrogen application reduced by 25%, the rice yield was not decreased, but increased in the range of 11.27 % to 19.75 %, with T4 treatment （＂Tiegan＂brand compound fertilizer and ＂Duowei＂ muhianomf）, both the rice yield and the nitrogen agronomic efficiency were the highest. Economic benefit analysis showed that with the organic compound fertilizer, the income increased in the range of 2 985 - 5 325 ynan/hm^2. With T4 treatment （＂Tiegan＂brand compound fertilizer and ＂Duowei＂ muhianomi）, the net income was the highest, reaching to 5 325 yuan/hm^2.
