[目的]探索适宜云贵高原的玉米花生最佳间作模式并筛选适合该模式的花生品种。[方法]通过随机区组设计,设置6种种植方式,成熟期收获测产,测量数据采用Excel和DPS数据统计分析软件进行分析。[结果]玉米花生间作体系较单作相比,具有明显的间作优势,土地当量比(LER)均大于1。玉米与云花生3号在2﹕2间作模式下LER为1.40,复合产量达到9 036 kg/hm2,玉米与云花生3号在2﹕2间作模式下玉米籽粒、鲜花生荚果及与干花生荚果净产值,分别比玉米单作增加182.63%、140.59%。云花生3号在单作及间作模式下较砚山当地常规种植花生品种相比,其产值分别比砚山当地常规种植花生品种最高可增加5 069、3 272 yuan/hm2。[结论]云贵高原玉米花生间作采用2﹕2间作模式,间作花生品种采用云花生3号,具有最高间作产量及经济效益优势,能最大限度提高土地利用率。
[Objective] The study aimed to explore the optimum intercropping pattern of corn and peanut in Yun-Gui Plateau and screen the peanut varieties suitable for this pattern. [Method] Six kinds of planting methods were set up by randomized block design. Harvesting was carried out at the mature stage. The measured data were analyzed by Excel and DPS data statistical analysis software. [Result] Compared with single cropping system, the intercropping system of maize peanut had obvious intercropping advantage. The land equivalent ratio (LER) was higher than 1. The LER was 1.40 and the compound yield was 9 036 kg / hm2 in 2: 2 intercropping maize and Yunanhuansheng 3, and the maize kernels, peanut pods and dried peanut pods The net output value increased by 182.63% and 140.59% respectively over that of corn alone. Compared with Yanshan local routine planting peanut varieties, the output of Yunan peanut No.3 increased by 5 069,3 272 yuan / hm2 than that of Yanshan local conventional planting peanut varieties in single and intercropping modes respectively. [Conclusion] The 2: 2 intercropping pattern was used for the intercropping of maize peanut in the Yunnan - Guizhou Plateau. The intercropping peanut variety Yunnanshen 3 had the highest intercropping yield and economic benefit, which could maximize the land use efficiency.
