A Study on Zoology and Biological Specific Properties ofBetula luminifera Winkl
Distribution, fit environment and growth property of B.huminifera Winkl from natural and plantation forests were studied. The result showed that B.luminifera is of light inclination, barren－resistance, strong adaptation and long growth period. The seeds of B.luminifera are difficult to store under normal temperature and they must be sown as soon as they are collected. Nursey stock of B.luminifera grows quickly and its height growth lasts an entire period while the peak of diameter growth for the nursey stock of B.luminifera is about one month later than that of height growth. Natural B.luminifera has more than twice growth peaks of diameter and height, its wood valume grows rapidly continually. The rapid growth period of B.luminifera from plantation forest is earlier with better capability. It’s renewing can be carried out by artificial plantation and germinatior on natural renewing enhanced artificially. The conclusion provides direction for protection, rational use and development of B.luminifera resource.
