山丁子播种与嫁接育苗技术试验

Analysis on the Propagations Techniques of Mlus baccata L.

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.
