摘　　要：Seedlings of Toona sinensis were planted in seeding and breeding ways to increase the yield of T. sinensis by raising the number of lateral branches of T. sinensis seedlings by means of cutting and pinching through sowing and breed- ing in containers and sand bed nursery. The results showed that： after cutting and pinching, seedlings with multi-lateral branches could be formed. The cutting treat- ment in the container had a small number of seedlings with over 2 lateral buds, and the lateral buds were weak. Some of the weak lateral buds disappeared with the growth going on, showing poor growth performance. The pinching treatment in the sand bed nursery found a large number of seedlings with more than 2 lateral buds, and the lateral buds could grow into lateral branches, forming the T. sinensis seedlings with multi-lateral branches. Proceed to cutting processing, the secondary and third-level lateral branches came into being, which could make the seedlings of T. sinensis have multi-head tree shape in 2-3 years.通过播种繁育方式,在容器和沙床育苗,采用短截、摘心等人工措施增加香椿苗木侧枝数量来定向培育多头香椿苗木,提高苗木品质,以提升香椿芽产量。结果表明:经过短截、摘心等措施,能形成多侧枝苗木。容器苗木短截处理,2个以上侧芽发生数量较少,侧芽较弱,继续生长,部分弱的侧芽消失,表现效果不好;沙床苗木摘心处理,2个以上侧芽的苗木数量较多,侧芽长成侧枝,形成多侧枝香椿苗木。继续进行短截处理,生成2级、3级侧枝,2~3年能形成多头树形的香椿苗木。
