摘　　要：采用田间小区试验研究了根瘤菌肥对花生主要性状及产量的影响。结果表明：施用花生根瘤菌肥的花生根瘤数、产量和经济效益均高于常规施肥处理；在常规施肥和常规施肥氮肥减半基础上施用根瘤菌肥处理比常规施肥的根瘤数、产量和经济效益分别增加64．08％-261．97％、7．9％-15．2％和2870．7-5083．5元/hm2，其中以常规施肥（N∶P∶K＝17∶11∶14）1125 kg/hm2＋15 kg/hm2固体花生根瘤菌肥穴施增产效果及经济效益最好。Field plot trials were conducted to study the influences of peanut rhizobia fertilizer on main characters and yield of peanut.The results indicated that the peanut nodule number,yield and economic benefit of peanut rhizobia treatment were all higher than those of conventional fertilization treatment.Applying peanut rhizobia fertilizer on the basis of conventional fertilization and nitrogen in half,the peanut nodule number,yield and economic benefit increased by 64.08%-261.97%,7.9%-15.2%and 2 870.7-5 083.5 yuan/hm2 re-spectively compared to the conventional fertilization.Among which,conventional fertilization（N∶P∶K=17∶1 1∶14, 1 125 kg/hm2 ）and hole applying 15 kg/hm2 solid peanut rhizobia fertilizer had the best yield -increasing effect and economic benefit.
