摘　　要：[目的]找出辣椒产量最高的辣椒-玉米的最佳间作密度。[方法]研究辣椒-玉米不同面积比下辣椒产量(值)、玉米产量(值)和净增产值,并采用插值分析近似获得玉米-辣椒其他占地面积比值间作密度下辣椒的产量情况。[结果]辣椒-玉米的不同间作密度其产量和产值有显著的区别,间作模式的总产值大小顺序依次为:辣椒-玉米(10∶2)、辣椒-玉米(15∶5)、辣椒-玉米(8∶4)、辣椒-玉米(8∶1)、辣椒单作。[结论]采用合理的间作密度可以有效地提高辣椒的产量和产值。[Objective ]This research is aimed to confirm the optimal intereropping density of pepper - corn which can gain the highest yield of pepper. [ Method] The effect of the yield of pepper, corn ,the output value of pepper, corn and the increased output value were studied. The yield of pepper on the other pepper - corn different intercropping density was obtained by data fitting （interpolation）. [ Result ] The yield and the output value of pepper- corn have striking difference if adopt different intercropping density, the order is pepper- corn（ 10：2 ） 〉 pepper- corn（ 15：5 ） 〉 pepper- corn（ 8：4 ） 〉 pepper- corn（ 8：1 ） 〉 pepper monocropping. [ Conclusion] The yield and the output value of pepper can be effectively increased if adopting rational intereropping density.
