近几年,香椿的栽植面积逐步扩大,但种子来源困难,即使采集到少量种子,播种后幼苗遭受冻害,成活率低。因此,我们在当地采集一些种根进行繁殖试验,结果成活率达95％,且易管理,质量好,成本低,具体技术是: 一、采集种根。一般在每年春季三、四月份采集种根,以幼树根为好,健壮母树上的根也可利用,树根挖出后,选择直径1.5～2厘米的根,将其剪成10～
In recent years, Toona sinensis planting area gradually expanded, but the seed is difficult to source, even if a small amount of collected seeds, seedlings after planting frost damage, low survival rate. Therefore, we collected some kinds of roots in the local area for breeding experiments, resulting in 95% survival rate, and easy to manage, good quality and low cost. The specific techniques are as follows: 1. Collecting rootstocks. Generally spring in April and April each year to collect kinds of roots, the young tree roots as well, the roots of robust mother tree can also be used, the roots dug out, choose the diameter of 1.5 to 2 cm of the root, cut it into 10 ~
