摘要/Abstract

摘要： 对钟萼木Bretschneidera sinensis实播育苗、苗木物候期生长及不同试验点与不同培育方式的苗木生长进行研究。结果表明，该树种种子经催芽后发芽率达90%以上，苗木高与地径生长期主要在4～10月，10月后进入木质化状态，生长期较短是影响生长量的重要原因；高温与强光照对苗木顶芽与幼嫩叶产生灼伤影响，高温季节需进行遮荫；在高温高湿季节，易遭受病虫害为害，需加强病虫害防治。不同育苗方法表明，该树种大田裸根苗培育比容器苗更有利于苗木生长；不同生长类型的生长情况表明，良好的遗传个体在苗期表现良好的生长潜能。

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.

Key words: Bretschneidera sinensis, seedling cultivation, phenological phase, annual growth law, growth-type
