摘　　要：[目的]建立较优的芝麻(Sesamum indicum)与花生(Arachis hypogaea L.)间作套种的配比及施肥技术。[方法]采用双因素(2种施肥方法和5种配比)随机区组设计,10个处理,3次重复,共30个小区,小区面积12.0 m2。2种施肥方法分别为C1[底肥(540 g/小区,(1∶4)、单作芝麻(CK1)和单作花生(CK2)。[结果]6行花生2行芝麻,每小区施底肥540 g复合肥+追肥90 g尿素处理,产值和土地当量比(LER)最高,分别为22 378.68元/hm2和1.56;芝麻产量641.64 kg/hm2,花生产量2 506.67 kg/hm2;产投比4.94;较单作花生、芝麻收益增加32.32%、95.97%。[结论]该研究可以为找到芝麻与花生的最佳种植配比和合理施肥提供理论依据。[Objective] The research aimed to establish a optimized combination of intercropping and fertilization application technology of intercropping sesame with peanut.[Method] The complete randomized block design of two factors,two fertilization application methods and five combinations of intercropping,was designed,with ten treatments and three repeats.There were thirty experimental plots and each plot was 12.0 m2.The two fertilization application methods were basal fertilizer 540 g compound fertilizer per plot（C1）＋ additional fertilization 90 g urea fertilizer per plot and basal fertilizer 540 g compound fertilizer per plot（C2）respectively.And the five intercropping density were 2 line sesame and 4 line peanut（M1）,2 line sesame and 6 line peanut（M2）,1 line sesame and 4 line peanut（M3）,only planning sesame（CK1） and only planning peanut（CK2） respectively.[Result] Output value and land equivalent ratio（LER） of C1M2 treatment were the highest with 22 378.68 yuan/hm2 and 1.56 respectively;Sesame yield was 641.64 kg/hm2,peanut yield was 2 506.67 kg/hm2;Output to input ratio was 4.94;The income was increased 32.32% and 95.97% compared with only planning peanuts and sesame treatments.[Conclusion] The study provides a theoretical basis for finding the best intercropping combinations of sesame and peanut and rational application fertilization.
