冬季为了防止苗木冻害,需要冬藏。日本北海道等寒冷地区都这样做。但是用大型低温贮藏库贮藏苗木,费用大,成本高,在民间小苗圃里因条件差不能使用。因此在寒冷地区需要研究出茁术冬季贮藏的简易方法。我们从1976年到1979年的四年期间对丰要造林村种的苗木进行了冬藏试验。一、试验材料采用冬藏用地苗木,苗龄和不同年度的贮藏苗木株数如表1。 Winter in order to prevent frost damage, need winter possession. Japan Hokkaido and other cold areas are doing so. However, the use of large-scale cold storage of seedlings storage, costly, high cost, poor conditions in private nursery can not be used. Therefore, in cold areas need to study a simple method of storage in winter. During the four years from 1976 to 1979, we carried out a winter-Tibetan experiment on seedlings of Fengye afforestation village. First, the test materials used in winter Tibet nursery stock, seedling age and different years of storage nursery stock number in Table 1.
