为了提高种子的产苗量、成苗率,从1980年开始,我们结合国外松大田育苗,苗床补缺,进行了芽苗移栽的试验,获得了成功.1981年,又在本场石洞工区苗圃,试用芽苗移栽的方法进行火炬松育苗.结果1.5市斤种子,产苗16,543株,每市斤种子产苗达到了11,028株,成苗率达到86.8%,且苗木健壮,平均高30.5厘米,基径达0.89厘米,最高的苗高达到52厘米,基径1厘米.现将二年来国外松芽苗移栽育苗中的一些主要技术措施总结如下:
In order to improve the seedling production rate and seedling emergence rate of seed, we have succeeded in the experiment of seedling transplanting combined with foreign seedling growth and seedling filling in Songda Field since 1980. In 1981, Nursery, the trial of seedling transplanting method for the cultivation of Pinus taeda.Results 1.5 kilograms of seeds, 16,543 seedlings, per kilogram of seed production reached 11,028 strains, the rate of seedlings reached 86.8%, and seedlings robust, an average of 30.5 Cm, base diameter of 0.89 cm, the highest seedlings up to 52 cm, the base diameter of 1 cm now two years abroad pine seedlings transplanted seedlings in some of the major technical measures are summarized as follows:
