摘要
以花色、花期、花美感、植株抗旱性、耐寒性等为评价指标,利用灰色关联理论与AHP(层次分析法)结合的层次-关联评判分析法,对引种到陕西关中地区的18种草本花卉进行了综合评判。结果表明:三月花葵(Lavatera trimestris)、冰岛罂粟(Papaver nudicaule)、苏丹凤仙(Impatiens sultanii)和风铃草(Campanula medium)的生长势较差,综合评价值也较低;牛舌草(Anchusa azurea)、肿柄菊(Tithoniao tundifilia)、毛地黄(Digitalis purpurea)和一串蓝(Salvia farinacea)等8种花卉能适应关中地区的环境,并且综合评价值较高,适宜在陕西等地区进一步推广应用。
Eighteen species of herbaceous flowers which were introduced from Canada were cultivated in Guanzhong plain of Shaanxi. The method of hierarchy-relation analysis of AHP in combination with grey relational grade theory were taken to do comprehensive evaluation based on the indicators of flower color, blooming period, flower aesthetics and Analyzing results indicated that Lavatera trimestris drought resistance, cold tolerance, and so on. , Papaver nudicaule, Impatiens sultanii and Campanula medium had low scores with poor adaptability; the other eight species flowers Anchusa azurea, Tithoniao tundifilia, Digitalis purpurea, Salvia farinacea which could adapt to the environment of Guanzhong plain had higher ornamental value and better adaptability, and they were worth to popularize in the areas around Shaanxi.
