摘　　要：栎树不仅是我国优良的园林景观树种,其还具备多种经济价值和生态价值。为更充分掌握栎树育苗成活情况,研究不同播种技术对栎树育苗的影响。分别以从美国宾夕法尼亚洲引进的北美红栎、柳叶栎和我国本土的麻栎作为试验对象,通过对栎树种子进行处理、催芽,以及对轻基质网袋容器进行处理后,分别使用轻基质网袋再移栽播种育苗、沙池播种育苗、苗圃地播种育苗三种播种方式分别对不同品种栎树进行播种,并分析不同播种技术对栎树育苗的影响。试验结果表明:我国本土麻栎在不同播种方式下出苗率最高,使用轻基质网袋再移栽播种育苗方式可保障不同品种栎树出苗率数值最高;使用苗圃地播种育苗方式播种的不同品种栎树,其地径数值最高。Quercus is not only an excellent landscape tree species in China,but also has various economic and ecological values.To better understand the survival status of oak seedlings,study the effects of different sowing techniques on oak seedling cultivation.Using North American red oak,willow oak,and Chinese native oak introduced from Pennsylvania in the United States as experimental subjects,different varieties of oak trees were seeded using three sowing methods:light substrate net bags for transplanting and seedling cultivation,sand pond sowing and seedling cultivation,and nursery sowing and seedling cultivation,And analyze the impact of different sowing techniques on oak seedling cultivation.The experimental results showed that the emergence rate of local Quercus acutissima in China was the highest under different sowing methods,and the use of light matrix mesh bags followed by transplanting and sowing can ensure the highest emergence rate of different oak varieties;Different varieties of oak trees sown using nursery sowing and seedling raising methods have the highest ground diameter values.
