摘　　要：为探明四川宜宾地区高粱大豆带状复合种植模式下的最优行株配比,以高粱品种宜糯红4号和大豆品种贡秋豆5号为材料,设置6种高粱大豆带状复合种植模式株行规格,研究了各处理对高粱和大豆的生育期、主要农艺性状、产量及产量构成因素和经济产值的影响。结果表明,不同处理对两种作物的生育期、主要农艺性状、产量及产量构成因素的影响较大。生育期方面,高粱、大豆株行间距越小,种植密度越大,会使高粱抽穗期和扬花期提早,生育期缩短;套作大豆生育期缩短。主要农艺性状方面,高粱、大豆株行间距越小,高粱的株高和穗下柄长度增加,茎粗和穗长减小;大豆的株高和底荚高度有所增加。产量及经济效益方面,以A3处理(高粱大豆带宽1.5 m,高粱、大豆种植密度均为9.0万株/hm^(2),高粱行距50 cm、窝距30 cm,大豆行距40 cm、窝距30 cm,两种作物行间距30 cm)的产量和经济产值较高,其中高粱产量4413 kg/hm^(2),套作大豆产量1831.5 kg/hm^(2),经济产值5.29万元/hm^(2)。研究结果为相关地区高粱大豆带状复合种植模式推广应用提供参考。To investigate the optimal row to plant ratio under the strip compound model of sorghum and soybean in Yibin City,Sichuan Province,sorghum variety Yinuohong 4 and soybean variety Gongqiudou 5 were used as materials,6 plant row specifications for the strip compound model were set of sorghum and soybean,and the effects of each treatment on the growth period,main agronomic traits,yield and yield composition factors,and economic output value of sorghum and soybean were studied.The results showed that different treatments had a great influence on the growth period,main agronomic traits,yield,and yield components of the two crops.In terms of growth period,the smaller the inter row spacing between sorghum and soybean plants,and the higher the planting density,the earlier the heading and flowering period of sorghum,and the shorter the growth period;the growth period of soybean intercropping was shortened.In terms of main agronomic traits,the smaller the inter row spacing between sorghum and soybean plants,the higher the plant height and stem length under the ear of sorghum,while the stem thickness and ear length decrease;the plant height and pod height of soybeans had increased.In terms of yield and economic benefits,the A3 treatment(sorghum soybean width of 1.5 m,planting density of 90000 plants/hm^(2) for sorghum and soybean,sorghum row spacing of 50 cm and nest spacing of 30 cm,soybean row spacing of 40 cm and nest spacing of 30 cm,and row spacing of 30 cm between the two crops) had higher yield and economic output value,with sorghum yield of 4413 kg/hm^(2),intercropping soybean yield of 1831.5 kg/hm^(2),and economic output value of 52900 yuan/hm^(2).The research results provide references for the promotion and application of strip compound model of sorghum and soybean in related regions.
