濒危树种钟萼木苗木年生长节律与适应性调查
Study on the Annual Growth Law and the Adaptation Growth of Seedlings for Endangered Tree of Bretschneidera sinensis
摘要
Abstract
The different cultivate methods and growth investigations of Bretschneidera sinensis seedlings during the phenological phase were studied. The results indicated that the sprout rate of B. sinensis was upto 90% by using germination treatment, the growth period of height and ground diameter was from April to October. The seedlings grew with more lignification after October. The shorter growth period was the main factor for the annual growth of B. sinensis. The terminal bud and tender leaf of seedlings would be burnt under the high temperature and strong light, so shaded light was necessary in high temperature season. In hot and humid season, the seedlings were easier to be harmed by plant pathogen and insect pests. The different cultivate methods of seedling indicated that naked-root seedling was more suitbale for transplanting comparing with container-seedling. The well genetic-individual was behave well in potential growth during growth-period of seedling.关键词
