摘要
为筛选适合云南地区种植的高产优质青贮玉米品种,用随机区组试验法设84个小区,对28个玉米品种进行物候期、适应性、植物学特性、饲用价值、种植效益等性状研究。结果表明:曲辰9号、胜玉5号、宣黄单7号、宣白单2号4个品种适应性好,茎秆粗壮,抗倒伏性强,营养含量丰富,蜡熟期植株绿色比例高于90%,植株鲜产超过100 t/hm2,产投比大于1.1。可推荐为亚热带及类似地区生产青贮玉米的首选品种。
The test was conducted with 28 maize varieties in 84 randomized plots to evaluate phenologi- cal period, botanical characteristics, feeding value, planting benefits of the varieties in order to select the varieties suitable for planting in Yunnan. The results showed that Quchen No. 9, Shengyu No. 5, Xuanhuangdan No. 7 and Xuanbaidan No. 2 performed better in terms of adaptability, thick stem, strong lodging-resistance, high nutrient content, high green plant ratio （ 〉90% ） at dough stage, high fresh yield over 100 t/hm2 and good proportion of output and input over 1.1, making the four varieties the top priority to grow for silage in the subtropical areas in Yunnan or the similar regions.
