摘要
通过景观型资源调查选育了景观价值较高的木麻黄优树,采用水培的方法进行繁殖,营养袋育苗和栽培测试,淘汰生活力差、成活率低和生长不佳的无性系,再经过二度重选,淘汰一些形状怪异、抗性差、主干歪曲严重、枝干颜色差、美学观赏感不足的无性系,最终筛选出15个景观型价值效果较好的优良无性系,为木麻黄属植物的园林应用打下坚定的基础,丰富园林植物造景的材料,实现木麻黄经济价值的提升。
In this study,some landscape-oriented plus trees were selected through survey and screening.These plus trees were propagated through rooted cutting using twigs,and clonal seedlings were measured in nursery.Some clones with poor growth vigor,lower survival percentage were culled in the first selection,and some clones with odd shape,poor resistance,poor aesthetic sensibility were eliminated in the second selection.Finally,15 clones with good landscaping value were selected for landscaping use in the future.
