杉木插条造林,过去都是砍伐桩萌条上山栽植。这种方法由于对插条的选择不严,优树伐桩的萌条甚少,不能获得较大的增产效果;同时伐桩萌条来源有限,不能满足大面积造林的需要,造林成活率一般也不高。为了获得大量的优质插穗,提高造林成活率,促使杉木速生丰产,几年来,我们营建杉木萌条采穗圃,解决了插穗来源,并利用萌条在圃地扦插育苗,培育扦插苗上山造林,已初见成效。一、营建萌条采穗圃杉木萌条采穗圃是精选杉木优苗,利用其萌芽力强的特性,作为提供优良无性繁殖材料的基地。其特点是:建圃较易,可连年采穗,萌条产量高、质量好,并能保持母树的遗传特性,管理方便,技术容易掌握,繁殖快,成本低,便于推广。
Cunningham cuttings afforestation, the past are cut pile sprouts up the mountain planted. This method because of the lax choice of cuttings, excellent bark piles little sprout, can not get a larger yield; the same time, the limited source of spruce can not meet the needs of large-scale afforestation, afforestation survival rate in general Not high. In order to obtain a large number of high-quality cuttings, improve the survival rate of afforestation, and promote fast-growing Chinese fir, in recent years, we build fir seed sprout nursery, to solve the source of cuttings, and the use of sprouts cuttings nursery in the nursery, cultivating cuttings uphill afforestation, Has achieved initial success. First, the construction of sprouts spruce Chinese fir sprouts sprouts is selected fir seedlings, the use of its strong germination characteristics as a base to provide excellent cloned reproductive material. The utility model is characterized in that it is easy to build nurseries and can be eared in successive years. The sprouting yield is high and the quality is good. The genetic characteristics of the maternal trees can be maintained, the management is convenient, the technology is easy to grasp, the breeding is fast, the cost is low, and the promotion is convenient.
