杉木采穗母树修剪方法的探讨

A Research on Clip Method of Cunninghamia Lanceolate Scion-seed Tress

通过对不同年龄的杉木使用截干、斜埋、剪枝等几种不同修剪方法的试验，比较各种不同方法产生穗条的数量及生根情况，确定一种可行的采穗母树剪定方法，为杉木采穗圃的营建与管理提供技术保证。结果表明在使用幼龄苗营建杉木采穗圃时，采用斜埋法产生穗条的数量最多且生根情况最好；如果要从年龄稍大一点的树中获取大量穗条或是建立长期的采穗圃，采用截干法，效果较好。

To select a good clip method of scion-seed tree so as to Provide a technical guarantee of making and managing a scion nursery of Cunninghamia Lanceolota. The authors have tested several kinds of clip methods such as pole-cutting.branch-buring and clipping with Cunninghamia lanceolata of different age. According to the tests,a conclusion can be made that the best method of making a scion nusery of Cunning- hamia Lanceolata with young sapling is branch-buring. It can make trees produce the most scions and root best. But to produce a large amount of scions from aged Cunninghamia Lanceolata or to make a permanent scion mursery,pole-cutting is the best method.
