摘要
通过对58种1年生地被植物在山西省进行引种栽培,旨在筛选出适应性强、观赏及生态价值高的地被植物,为增加山西省1年生地被植物种类、创造丰富多彩的园林景观提供一定的参考依据。采用层次分析法对引种植物的花色、花型、花径、株高等18个指标建立地被植物评价模型,并对引种植物进行适应性综合评价,确定适应性等级。结果表明,试验中评为I级的植物有小百日草、百日草、鸡冠花、紫茉莉,这4种植物表现为适应能力强、观赏和生态价值高;II级植物有勿忘草、凤仙、茼蒿菊等39种,长势良好,观赏效果较好;III级植物有马洛葵、花葵、五色菊等15种,观赏一般,且综合适应性差。58种植物中有43种可在山西省进行开发利用,评定为III级的植物需进一步引种试验研究。
5Through the introduction and cultivation of 58 annual ground cover plants in Shanxi province, the purpose is to selectthe ground cover plants with strong adaptability, high ornamental and ecological value. And it can provide certain reference for increasingthe species of annual ground cover plants and creating rich and colorful landscape in Shanxi province. The evaluation model ofgroundcover plants was established by using Analytic Hierarchy Process（AHP） for 18 indexes of flower color, pattern, flower size andplant height of introduced plants. Meanwhile, the adaptability of introduced plants was evaluated. Finally, the level of plant adaptabilitywas determined. The result showed that in this experiment, plants rated gradeⅠhad Zinnia angustifolia, Zinnia elegans Jacq., Celosiacristata L. and Mirabilis jalapa L.. These four plants showed strong adaptability, high ornamental and ecological value. Grade II had 39kinds of Myosotis silvatica Ehrh. ex Hoffm., Impatiens balsamina L., Chrysanthemum frutescens and so on, which had good growth and good ornamental effect. Grade III plants included 15 species, such as Malope trifida, Lavatera arborea Lin, Brachycome iberdifolia, etc.,which were generally ornamental and had poor comprehensive adaptability. Among the 58 plants introduced, 43 species can be exploitedand utilized in Shanxi province. For grade III plants, we need further introduction and cultivation.
