| 摘 要： | 对中北410等5个国审青贮玉米杂交种在不同地区、不同密度条件下的生物产量和农艺性状进行了研究。结果表明:(1)不同品种之间,生物产量存在极显著差异。奥玉5102、中北410和雅玉8无显著差异,但极显著高于农大108和辽625;(2)不同地点对青贮玉米杂交种的生物产量影响很大;(3)不同密度对生物产量影响较大,较高的种植密度可以获得较高的生物产量;(4)在生物产量方面,品种与地点存在互作;品种与密度只在通州存在互作;密度与地点无互作。综合分析供试品种在不同环境条件下的表现,笔者认为,中北410丰产性、适应性较好,适合在北京地区大面积推广,每公顷适宜种植密度为6.75×104株。

| Abstract: | The study on forage yield and agronomic traits of five silage hybrids under different planting densities in different areas was carried out in order to select best silage hybrid suitable in Beijing area.The results indicated:1)There were significant differences among varieties in forage yield.There were no significant differences in forage field among AoYu5102,ZhongBei410 and YaYu8,but they were higher than NongDa108 and Liao625 significantly.2) The forage yield were affected by the area.3) The forage yield were also affected by planting density.Higher planting density tended to increase forage yield.4) The interaction on forage yield was existed between variety and area and the interaction on forage yield was existed between variety and planting density only in TongZhou.5) ZhongBei410 was suitable in Beijing area,which produced high forage yield.The best planting densities was 67 500/hm~(2). |
