摘要
从1980年起,先后在湖南省零陵地区林科所和江永县高泽源林场营建杉木采穗圃7.5亩。实践表明:杉木采穗圃繁殖系数大、产量高,且技术容易掌握,便于推广,是加速杉木造林良种化的有效途径。同时说明,科学地选择建圃材料,采用浅栽、控制冠幅、弯干和截顶,以及加强对圃地的经营管理,是实现建圃目标,提高穗条产量和质量的关键措施。
In Forest Science Research Institute of Lingling Prefecture and GaozeyuanTree Farm of Jiangyong County, Hunan, 0. 5 ha China fir scion nurserieshave been established since 1980. Results indicate that China fir scion nurseryis the effective way to expedite the tree improvement because of its highpropagation coeffecient and yield and its easy techniques for convenientextention. Furthermore, selecting scientifically the planting material for thenursery establishment, planting shallowly, controlling the crown width,bending and stumping back the planting stock, and strengthening the nurserymanagement are the key measures to achieve the goal of the nursery and toraise the quantity and quality of the scion.
