1983年以来,省林科所有关课题组,对泡桐芽苗移栽育苗进行了试验,获得了良好的效果。用这一技术培育的泡桐实生苗,当年(白花桐)平均苗高4.24米,平均地径5.45厘米,接近或超过1年生泡桐埋根苗的高、径生长量。与一般大田播种育苗相比,用种量从每亩500克减少到0.67克,种子利用率提高了800多倍。为了把这一技术比较全面的作一介绍,我们选登了三篇虽属大同,也有小异,且各有侧重的文章,供参考。
Since 1983, the Provincial Forestry Branch of all relevant research groups, the Paulownia seedlings transplanted seedlings were tested and achieved good results. With this technology to cultivate Paulownia seedlings, the year (white flower Tong) average height of 4.24 m, an average diameter of 5.45 cm, close to or more than 1 year Paulownia seedlings root height and diameter growth. Compared with the general nursery sowing seeding, with the amount of 500 grams per acre reduced to 0.67 grams, seed utilization increased by 800 times. In order to make this technology a more comprehensive introduction, we have voted for three articles, which belong to Datong but also have small differences and have focused articles for reference.
