摘要
对从加拿大引进的16种草花进行为期两年的观察试验,研究其出苗成活率、绿期、花期情况,并对其观赏价值进行灰色关联分析,筛选出7个品种可直接用于园林绿化,其他品种也具有很好的育种价值,丰富了关中地区城镇园林绿化种类。
Selecting the herbaceous flowers which could adapt to the natural and ecological condition in Shaanxi. The sixteen species of herbaceous flowers from Canada were observed by the planting trial for two years. The seed germination rate, plant survival rate, plant green period and blooming period were studied, and their ornamental values were evaluated by gray-correlation analysis. It was suggested that seven herbaceous flowers could be potential ornamental plant types in the Guanzhong Shaanxi, the rest of introduced varieties had some potential breeding value.
