红松是我省及东北地区更新造林的主要树种之一。为满足更新造林大发展的需要,各地大力培育红松苗木。但是,由于红松种子种皮坚硬,种子休眠期较长等原因,在育苗生产中,采取较长的时间对种子进行催芽法处理种子。有的采取隔年埋藏法有的采取隔冬埋藏法进行催芽处理,这些方法各有利弊,主要问题:一是催芽处理种子时间较长;二是种子埋藏之后,难于测定种子的温度和湿度;三是不能人为的控制好种子处理的进程,更不能掌握好催芽处理种子的种胚变化情况;四是窖藏的地点选择不当(地下水位较高的地方),时常发 Korean pine and pine in Northeast China and the reforestation is one of the main tree species. In order to meet the needs of the rejuvenation of afforestation, nurturing red pine seedlings everywhere. However, due to the hard seed coat of Pinus koraiensis seeds and the long dormancy period of seeds, the seed takes more time to germinate the seeds during seedling production. Some adopt the method of burial every other year to adopt the winter planting method for germination. These methods have their advantages and disadvantages. The main problems are as follows: one is the germination of seeds for a long time; the other is that after the seeds are buried, it is difficult to determine the temperature and humidity of the seeds; Can not be artificially controlled the process of seed treatment, but also can not grasp the germination of seed germination embryo changes; Fourth, the location of cellaring improper selection (groundwater level higher), often
