[目的]探明洪江市获得最佳大豆与玉米产量和经济效益的种植模式。[方法]于2024年以当地大豆、玉米单作传统种植模式为对照，开展了大豆玉米带状复合种植作物产量及经济效益的研究。[结果]复合种植模式大豆和玉米植株的整个生育期均比传统种植模式增加3 d。复合种植模式大豆和玉米植株的株高分别比传统种植模式增加11.8和10.7 cm。复合种植模式大豆的单株有效荚数、单株粒数、百粒重均显著高于传统种植模式，玉米植株的行粒数、单穗重、每穗粒重和百粒重均显著高于传统种植模式。复合种植模式大豆和玉米产量均显著高于传统种植模式，其产量分别比传统种植模式增加15.24%和5.65%;大豆和玉米的总产值和总净收益分别比传统种植模式增加9.28%和37.35%。[结论]复合种植模式是一种增加大豆、玉米产量及经济效益的有效种植模式。

[Objective] In order to explore the planting mode that achieves the best soybean and maize yield and economic benefits in Hongjiang City. [Method] In 2024, a study on the yield and economic benefits of soybean and corn strip intercropping was conducted by taking the local traditional monoculture model of soybeans and corn as a control. [Result] The whole growth period of soybean and maize plants were both increased by 3 days with strip compound planting, compared with traditional planting pattern. Plant height of soybean and maize plants were increased by 11.8 and 10.7 cm with strip compound planting, compared with traditional planting pattern, respectively. Meanwhile, this result indicated that number of effective pods per plant, number of grains per plant, and hundred grain weight of soybean with strip compound planting were significantly higher than that of traditional planting pattern, while the number of grains per row, single ear weight, grain weight per ear, and hundred grain weight of maize plants with strip compound planting were significantly higher than that of traditional planting pattern. The yield of soybeans and maize with strip compound planting were obviously higher than that of traditional planting pattern, yield of soybean and maize with strip compound planting were increased by 15.24% and 5.65%, total output value and total net income with strip compound planting were increased by 9.28% and 37.35%, compared with traditional planting pattern, respectively. [Conclusion] It was an benefit planting pattern for improving yield and economic benefits of soybean and maize with strip compound planting in the hilly areas of central Hunan, China.
