摘　　要：[Objective] The research aimed to establish a optimized combination of intercropping and fertilization application technology of intercropping sesame （Sesamum indicum） and peanut（Arachis hypogaea）. [Method] Double factor randomized block design （2 fertilization methods and 5 ratios） was adopted, with 10 treatments, 3 repeats. There were a total of 30 plots, with plot area of 12.0 m2. Two fertilization methods included C1 [base fertilizer （540 g/plot compound fertilizer ＋ topdressing （90 g urea）] and C2 [all as base fertilizer （540 g/plot compound fertilizer）]. Five different proportions （sesame： peanut） were M1（2∶4）, M2（2∶6）, M3（1∶4）, monoculture sesame （CK1） and monoculture peanut （CK2）, respectively. [Result] Output value and land equivalent ratio （LER） of C1M2 treatment （6 lines peanut/2 lines sesame, base fertilizer 540 g/plot （compound fertilizer） ＋ （topdressing urea 90 g） were the highest of 22 378.68 yuan/hm2 and 1.56 respectively; sesame yield was 641.64 kg/hm2 and peanut yield was 2 506.67 kg/hm2. Output-input ratio was 4.94. The income was increased by 32.32% and 95.97% compared with only planting of peanuts and sesame. [Conclusion] The study provided a theoretical basis for finding the best intercropping combinations of sesame and peanut and rational application fertilizations.[目的]建立较优的芝麻与花生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12.0m2。2种施肥方法分别为C1[底肥(540g/小区,复合肥+追肥(90g/小区,尿素)]和C2[全部作底肥(540g小区,复合肥)]。五种配比(芝麻:花生)分别为M1(2∶4),M(22∶6),M(31∶4),单作芝麻(CK1),单作花生(CK2)。[结果]6行花生2行芝麻,每小区施底肥540g,复合肥+追肥90g尿素处理,产值和土地当量比(LER)最高,分别为22378.68元/hm2和1.56;芝麻产量641.64kg/hm2、花生产量2506.67kg/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。
