摘　　要：[目的]为锐齿槲栎在园林绿化中的应用提供理论基础。[方法]以优选的锐齿槲栎种子为材料,研究了其种子参数、育苗技术和苗木生长规律。[结果]优选的锐齿槲栎种子净度为95%,种子长度为1.5～2.0cm,千粒重为2112～2897g;该树种大田育苗播种量为400g/m2,苗木密度为70～80株/m2,其苗高生长高峰期为7月下旬～9月下旬,茎生长高峰期为8月～9月,期间应加强水肥管理,促进苗木生长;1年生锐齿槲栎幼苗平均苗高可达54.3cm,平均地径可达0.74cm,>5cm的Ι级侧根数平均为14.8条,根系发达,可出圃造林。[结论]该研究为锐齿槲栎的幼苗培育和苗木质量鉴定提供了参考。[ Objective ] The study was to provide the theoretical basis for the application of Quercus glandulifera var. acuteserrata Maxim. in landscaping. [ Method] With the optimal Q. glandulifera var. acuteserrata seeds as the materials, the seed parameters, breeding techniques and seedling growth rhythm of Q. glandulifera var. acuteserrata were studied. [ Result] The seed purity of the optimal Q. glandulifera var. acuteserrata seeds was 95% with seed length of h 5 -2.0 cm and 1 000-seed weight of 2 112 - 2 897 g. Its field seedling rate for breeding should be 400 g/m^2 and seedling density should be 70 - 80 plants/m^2. The growth peak of seedling height was from the last ten ：days of July to the last ten days of September, and the growth peak of its stem was from August to September, in this period, water and fertilizer.lnanagement should be strengthened to promote the growth of seedlings . The average height of 1 year old Q. glandulifera var. acuteserrta seedlings was 54.3 cm with average ground diameter of 0. 74 cm, and the number of Ⅰ developed root system, and the seedlings could be used for afforestation. grade lateral root which length was above 5 em was 14.8 strips with [ Conclusion ] The study provided the reference for seedling culture and quality identification for Q. glandulifera var. acuteserrata.
