摘　　要：[目的]探索提高青钱柳种子育苗效率的方法。[方法]采用处理Ⅰ(去皮种+清水浸泡+清水拌沙藏)、处理Ⅱ(去皮种+GA3溶液浸泡+GA3溶液拌沙藏)、处理Ⅲ(酸蚀种+GA3溶液浸泡+GA3溶液拌沙藏)3种综合处理播种育苗措施进行育苗试验,研究不同处理对催芽效果、出苗特性、出苗率、苗木生长及病虫害的影响。[结果]处理Ⅲ的种子发芽最早,出苗数量较多,且较稳定;处理Ⅰ、Ⅱ、Ⅲ的总出苗率分别为14.59%、17.36%、4.51%。方差分析显示,3种处理播种育苗总出苗率差异不显著,而第1年与第2年的出苗率均为差异显著。[结论]处理Ⅱ较好打破种子休眠,总出苗率最高,是青钱柳种子育苗的优良处理措施。[ Objective ] To explore the method of raising the efficiency of seedling raising of Cyclocarya paliurus. [ Method ] Using three corn prehensive treatments, treatment I （ peeled seeds ＋ clear water immersion ＋ clear water mixed sand reservoir）, treatment ]] （ peeled seeds GA3 solution immersion ＋ GA3 solution mixed sand reservoir）, treatment In （ acid pickling ＋ GA3 solution immersion ＋ GA3 solution mixed sand reservoir）, effects on germination, emergence characteristics, rate of emergence, seedling growth and plant diseases and insect pests wet studied. [ Result] Seed germination was the earliest, the number of seedlings was large and stable in treatment Ⅲ ;total emergency rate i~ treatment Ⅰ, Ⅱ, Ⅲ were 14.58%, 17.36%, 4.51% respectively. Analysis of variance showed that there was no significant difference in the total seedling emergence rate among three treatments, but the seedling emergence rate was significantly different between the first and sec ond years. [ Conclusion] Treatment Ⅱ can break seed dormancy with highest seed emergency rate, which is a good measure for seed breedinl of C. paliurus.
