洋桔梗花型丰富优美，花色艳丽，花期长，适应性强，可用于盆栽和温室种植，也是理想的切花材料。洋桔梗种子细小且价格昂贵，为改变洋桔梗杂交种从国外进口的现状，经过大量的洋桔梗杂交制种试验，从播种及育苗、定植、杂交授粉、病虫害防治、采收等方面总结了甘肃省河西地区洋桔梗杂交种生产关键技术，以期为当地或同类型地区洋桔梗种子生产提供参考。

Eustoma grandiflorum features abundant and elegant flower forms, vibrant colors, prolonged blooming periods, and strong adaptability, making it suitable for pot cultivation and greenhouse production as well as an ideal cut flower species. However, seeds of Eustoma grandiflorum are small in size and relatively expensive. Therefore, this study aimed to reduce dependence on imported hybrid seeds through extensive hybridization and seed production experiments. The key production techniques for hybrid seed production in the Hexi Region of Gansu Province were summarized, including sowing and seedling cultivation, transplanting, hybrid pollination, pest and disease control, and harvesting. The results would provide technical references for Eustoma grandiflorum hybrid seed production in Gansu and other similar regions.
