由于雪水中的重水比一般水中的重水少,用雪水处理种子能促进树木种子提早发芽。东北林学院哈尔滨实验林场作了试验,效果较好。其方法是:将400粒纯洁的落叶松种子分成两组,分别用自来水和雪水浸18小时,然后取出放在处理好的发芽床上,种子要排列整齐,相互间不接触。发芽 As the heavy water in the snow water is less than the heavy water in general water, treating the seed with snow water can promote the early germination of the tree seed. Northeast Forestry College Harbin Experimental Forest Farm made a test, the effect is better. The method is: 400 pure larch seeds are divided into two groups, respectively, tap water and snow soaked for 18 hours, and then removed on a well-treated germination bed, the seeds to be arranged neatly, without contact with each other. germination
