摘　　要：[目的]掌握影响文冠果播种育苗成败的因子。[方法]通过对种子分级及苗圃地土壤水分管理进行对比试验,探讨种子分级及苗期土壤水分管理对文冠果出苗率和苗木质量的影响。[结果]苗圃地土壤水分管理是影响文冠果播种育苗成败的重要因素,种子分级影响出苗整齐程度及苗木质量。[结论]文冠果种子分级后播种,能提高出苗率和整齐度;对苗圃地土壤水分实行分期管理,可提高苗木质量和合格苗木出苗率。[Objective] The aim was to explore the factors for influcing the success or failure of semination of Xanthoceras sorbifolia Bunge. [Method] The influence of seed grading and seedling soil water management on seedling emergence and seedling quality of Xanthoceras sorbifolia Bunge was studied, by contrast test with seed grading and viability of soil water management. [Result] The results showed that seedling soil water management was the important factor for influcing the success or failure of Xanthoceras sorbifolia Bunge.Semination, and seed grading could affect neat degree of emergence and seedling quality. [Conclusion] Seeds of Xanthoceras sorbifolia Bunge. sowing after classification could improve the germination rate and uniformity.And stage management of soil moisture in viability could improve the quality of the seedling and seedling emergence rate of qualified.
