我们针对苗木越冬贮藏易失水、干梢等现象,在总结历年苗木窖藏方法的基础上对苗木越冬保护工作进行了研究和探讨。在1981年冬进行了苗木窖藏雪培的越冬方法试验。通过三年对比实验证明,该法可保持苗木新鲜,避免苗木失水(苗木干梢率平均降低7.9%),对提高更新造林成活率有极其明显的作用。1986年我局已经进行了全面推广和应用,并取得较好的效果。一、窖藏方法 We deal with the phenomenon of over-winter storage of seedlings such as water loss and dry shoots. Based on the summary of the methods of seedling storage in the past years, we conducted research and discussion on the protection of seedlings overwintering. In the winter of 1981, snow-covered seedlings were plowed over the wintering method. Through three years of comparative experiments show that the law can keep the seedlings fresh, seedlings to avoid water loss (seedling shoot average rate of 7.9%), to improve the survival rate of reforestation has a very significant role. In 1986 our bureau has carried out a comprehensive promotion and application, and achieved good results. First, the method of storage
