为了确保兴安落叶松育苗的成功,在播种前需要对种子进行催芽处理。我们甘河林业公司种子园采用的催芽方法是种子雪藏。其具体作法如下: 在12月中旬,先将种子用温水泡12小时,捞出后,用0.3％的高锰酸钾溶液消毒15～20分钟,清洗后,再将种子与雪混拌(比例为1:3)装入容器(木箱、草袋子)内,放置在低温处,用雪埋住容器进行贮藏。春季离播种前8天左右把种子取出来 In order to ensure the success of Larix seedlings, seed need to be germinated before sowing. The germination method we use in the seed orchard of Gan River Forestry is seed snow. The specific practices are as follows: in mid-December, the first seed soak with warm water for 12 hours, remove and disinfect with 0.3% potassium permanganate solution for 15 to 20 minutes, after washing, and then mix the seeds and snow (ratio 1: 3) into the container (wooden box, grass bag), placed at low temperatures, the container was buried with snow for storage. In the spring about eight days before sowing the seed is taken out
