[目的]杈叶槭是我国特有的槭树科槭属秋色叶树种之一,为了使这种珍稀树种资源尽早得到开发利用.[方法]从2006年起,对杈叶槭生物学和生态学特性进行了原产地调查和引种观察,对其种苗繁育和人工栽培技术进行了连续的试验研究.[结果]杈叶槭对土壤、气候等生态条件的适应性较强；杈叶槭种子育苗应采取种子沙藏、催芽和苗期遮荫等技术措施才能成功.[结论]杈叶槭可以作为一种优良的乡土彩叶树种在河南低海拔地区及相似生态类型区进行繁殖和推广应用,今后应加强杈叶槭的选种育种研究.%[Objective] To develop the rare resources of Acer robustum Pax as early as possible, which belong to the genus of Aceraceae endemic to China. [Method] The biological and ecological characteristics of the origin of Acer robustum Pax were investigated since the year of 2006, and its seed breeding and artificial cultivation techniques were studied through continual experiments. [ Result] Acer robustum Pax has strong adaptability to soil, climate and other ecological conditions. In order to achieve the successful breeding of seedings, it is necessary to store seeds in sand, pregermination, shade at seeding stage and other technical measures. [ Conclusion ] Acer robustum Pax is an excellent local coleus species which can be used for propagation and promotion in low-elevation areas in Henan Province and other similar ecological zones, the selection and breeding research of Acer robustum Pax should be strengthened in the future.
