日本五针松(Pinus parviflora Sieb.etZuee.)原产日本,是庭园绿化和制作盆景的珍贵树种。我国引种时间虽较长,但未结实。因此,一直用无性繁殖。1985年我们又从日本引进日本五针松种子3,300粒。采用三种方法进行催芽,培育成芽苗后移栽到小盆中。一、种子催芽将种子分成三份分别用三种方法催芽。1.先用0.1%的新洁尔灭消毒1分钟,再用40℃水浸泡24小时,捞出后放30%双氧水中浸20分钟,再捞出放湿砂中层积10天后取出,用小铁锤敲裂种子胚根部位的外壳,最后用30%双氧水浸3分钟,即可播种。2.用0.1%新洁尔灭消毒,40℃温水浸种24小时后捞出,敲裂种壳,再用30%双氧水浸种20分钟后播种。
Japanese Pinus parviflora (Sieb.etZuee.) Originated in Japan, is a landscaping and production of precious bonsai tree species. Although China introduced a long time, but not strong. Therefore, has been used for asexual reproduction. In 1985, we imported another 3,300 seeds of Japanese pine from Japan. Using three methods for germination, budding transplanting into small pots. First, the seed germination The seed is divided into three were used three methods of germination. 1. First disinfection with 0.1% benzalkonium bromide for 1 minute, and then soaked in water for 40 hours at 40 ° C, remove and put 30% hydrogen peroxide immersion for 20 minutes, and then remove the wet sand in the plot for 10 days and then removed with small hammer knock Split seed radicle area of the shell, and finally soaked with 30% hydrogen peroxide for 3 minutes, you can sow. 2. With 0.1% benzalkonium bromide disinfection, 40 ℃ warm soaking 24 hours after the fish out, knocked the shell, and then 30% hydrogen peroxide soaking 20 minutes after sowing.
