通过新品种引进筛选，解决酒泉市花卉产业新品种研发滞后、难以满足市场多样化与高品质需求的问题，为酒泉市花卉产业发展和升级提供参考。以引进的 20个草本花卉品种为试验材料，系统观测其物候期、形态特征与适应性，并基于植物观赏性(花期、感官评价)和生态适应性(成活率、抗逆性)进行综合评价。结果表明，中花百日草品种繁花的株高最高，为 91.67 cm，其生态适应性与中花百日草品种天才表现一致，二者抗逆性较好，成活率均达 93%以上；矮牵牛品种美声、虹彩的花色丰富，花期较长，均超过 110 d，且抗逆性表现良好；鸡冠花品种羽焰的花高最高，可达 15.00 cm，花期较长(111 d)且感官评分最优(13.74分)；中花百日草品种丰盛的花色多样且具备渐变特征，生态适应性良好，成活率为 90%；千日红品种侏儒的花期最长，可达 124 d，初花前期最短，仅有 29 d。通过层次分析法评估，中花百日草品种天才和繁花及丰盛、矮牵牛品种美声和虹彩、鸡冠花品种羽焰、千日红品种侏儒的综合评分等级较高。此类草本花卉的观赏性强、表型优良且适应性好，是适宜酒泉市推广的优良品种。

This study aimed to address the lag in the research and development of new varieties in the flower industry of Jiu.quan City and the difficulty in meeting diversified and high-quality market demands through the introduction and screening of new va.rieties, thereby providing a reference for the development and upgrading of the local flower industry. 20 introduced herbaceous flowervarieties were used as experimental materials, and their phenological periods, morphological characteristics, and adaptability were sys.tematically observed. A comprehensive evaluation was conducted based on plant ornamental value, including flowering duration andsensory evaluation, and ecological adaptability, including survival rate and stress resistance. Results showed that the medium-flow.ered zinnia variety Fanhua had the greatest plant height, reaching 91.67 cm. Its ecological adaptability was consistent with that of themedium-flowered zinnia variety Tiancai. Both varieties exhibited good stress resistance, with survival rates reaching above 93%. Thepetunia varieties Meisheng and Hongcai had rich flower colors and long flowering periods, both exceeding 110 d, and also showed goodstress resistance. The cockscomb variety Yuyan had the greatest flower height, reaching 15.00 cm, with a relatively long flowering peri.od of 111 d and the highest sensory evaluation score of 13.74. Medium-flowered Einnia variely Fengsheng exhibited diverse flower col.ors with gradient characteristics, good ecological adaptability, and a survival rate of 90%. The globe amaranth variety Zhuru had thelongest flowering period, reaching 124 d, and the shortest period before initial flowering, only 29 d. Based on evaluation using the ana.lytic hierarchy process, the medium-flowered zinnia varieties Tiancai, Fanhua and Fengsheng, the petunia varieties Meisheng andHongcai, the cockscomb variety Yuyan, and the globe amaranth variety Zhuru achieved relatively high comprehensive scores. Theseherbaceous flower varieties have strong ornamental value, excellent phenotypes, and good adaptability, making them superior varietiessuitable for promotion in Jiuquan City.
