| 中文摘要: |
| 剑江沿阶草是贵州省草业研究所培育的适宜于我国长江以南降雨量在800 mm以上亚热带地区种植的观赏草新品系。为了为该新品种的培育及其合理栽培、应用及推广奠定基础，2009—2011 年在江苏南京、广东增城、贵州独山、贵阳等不同生态条件下进行品种区域试验，对其农艺性状、观赏性、抗性及营养体繁殖速度进行鉴定比较和分析评价。结果表明：剑江沿阶草新品系在4 个试点均能正常生长繁殖，全年青绿；与原始群体和普通沿阶草相比，该品种的耐荫性和抗性强，观赏性和繁殖率高，是景观绿化优良品系。 |
| 英文摘要: |
| Ophiopogon japonicus ‘Jianjiang'is a new strain bred by Guizhou Pratacultural Institute, which is suitable for the subtropical area that the rainfall is over 800 mm in Southern Regions of Yangtze River of China. In order to promote the breeding, cultivation and application of O. japonicus ‘Jianjiang’, we conducted the variety comparative trial in 2009-2011 under such different ecological conditions as Jiangsu Nanjing, Guangdong Zengcheng, Guizhou Dushan and Guizhou
Guiyang. The agronomic character, ornamental, resistance and vegetative propagation speed were compared and analyzed.
The results showed that O. japonicus ‘Jianjiang’could grow and reproduce normally in 4 pilots; Compared with the
original group and ordinary variety, O. japonicus ‘Jianjiang’presented as strong shade tolerance and resistance, high
ornamental and reproductive rate, It’s an excellent variety of landscape greening. |
