摘　　要：为明确鲜食糯玉米-鲜食大豆带状复合种植模式下最佳行比配置,设置4种不同种植行比的田间配置和对照处理,分析不同行比对鲜食糯玉米和鲜食大豆生长和产量的影响,并进行综合效益分析评价。结果表明,与净作(CK)相比,不同行比间作配置使苏玉糯11和苏甜糯818的株高和穗位高分别增加了3.28%、3.01%和3.32%、5.37%。鲜食糯玉米-鲜食大豆带状复合种植下苏甜糯818和苏玉糯11的产量与CK相比降幅分别为13.46%、36.38%。比较不同行比配置发现,1行玉米3行大豆(1M3S)处理可获得最佳经济效益,苏玉糯11和苏甜糯818间作系统净收益分别达到882.5、1239.1元/667 m^(2),而纯作收益仅分别为640.6、731.4元/667 m^(2),说明株高较矮的苏甜糯818间作系统下玉米和大豆产量和经济效益更好,苏甜糯818可能更适合作为鲜食糯玉米-鲜食大豆复合间作的优选品种进行推广。To clarify the optimization of intercropping strip ratio of fresh maize and fresh soybean,4 different strip ratios and control was set to analyze the effects of the treatments on growth and yield in fresh waxy maize and fresh soybean and consequently evaluate the comprehensive benefit.The result showed that strip intercropping system of Suyunuo 11 and Sutiannuo 818 increased plant height and ear height by 3.28%,3.01%and 3.32%,5.37%respectively,compared with sole maize(CK).Yield of Suyunuo 11 and Sutiannuo 818 under strip intercropping system decreased by 13.46%and 36.38%respectively.In comparison to economic benefits of different strip intercropping systems,1M3S treatment achieved the best economic benefit,of which were 882.5 yuan/667 m^(2) and 1239.1 yuan/667 m^(2) respectively for Suyunuo 11 and Sutiannuo 818,and the CK treatments were only 640.6 yuan/667 m^(2) and 731.4 yuan/667 m^(2),which indicated that Sutiannuo 818 with lower plant height had better yield and economic benefit under strip intercropping system,and could be a preferable waxy maize cultivar in promotion of strip system.The study could provide theoretical basis for optimization of high-yield and high-efficient field configuration technology of strip intercropping of fresh maize and fresh soybean.
