| 摘 要： | 研究表明:桤木无性系植株嫩枝总芽数主要取决于树龄和无性系遗传特性,同时与无性系植株定干高度、修枝、施肥等密切相关。在桤木无性系采穗圃中,无性系植株定干高度以90 cm为宜,无性系植株枝条宜进行轻短截,并加强施肥管理,既可提高嫩枝总芽数,又能扩大树冠,增强树势,提高采穗圃穗条的产量和质量。

| Abstract: | The results of experiments showed that: the total twig numbers of clone plants of Alnus cremastogyne was mainly determined by trees age and clone characters,and closely related with clone plant heading height,punning and fertilizer.In the Alnus creamastogyne clone cutting orchard,the best heading height was 90 cm,the best cutting for clone plant was light and short cottage,while strengthen the fertilizer.It was not only increase the total number of the twigs and the canopy,but also increase the cutting's production and quality. |
