山丁子播种与嫁接育苗技术试验

摘要

山丁子主要繁殖手段是播种和嫁接。本试验通过对山丁子种子不同处理的发芽率进行研究对比，结果表明：低温沙藏发芽最早，播种后第5天可见60％种子发芽；从发芽率来看，播种和扦插繁殖是山丁子育苗的可行方式；对于播种来说，采种后进行低温沙藏处理播种后效果最好，发芽最快，发芽率最高，发芽率能达到95.8％；对于嫁接来说，劈接在成活率和当年生长量上比芽接好，分别提高16.88％和115.15％。在接穗充足，用工不紧张的情况下，劈接是更好的无性繁殖手段；在接穗不足，用工紧张的情况下芽接也是很好的无性繁殖手段。%In this paper,differences of affluence of different seed treatment is studied,the result show us that cold sand storage treatment performs batter than other treatments;the different effects of bud grafting and cleft grafting are analyzed and the result show us that :on the item of survival rate and height growth of seedlings from cleft grafting perform better.
