摘要
本文对伯乐树进行了定位物候观测,详细研究了它的生长发育规律和物候特征,结果表明:伯乐树的芽有两种类型;伯乐树的生长、发育节律与其生物学、生态学习性有着密切的联系;根据这些规律,提出了扩大伯乐树种群数量的方法有两个途径和相应的技术。这些技术方法将为进一步开展伯乐树的保育和扩大种群数量提供参考。
Growth and development rhythm and phenological characteristics of Bretschneidera sinensis Hemsl is discussed in this paper by orientation observation on phenology of this species. The re- sults show that the buds of Bretschneidera sinensis Hemsl. have two types;the growth and development rhythm of this species has clear relationship with its biological and ecological habits. Based on these results, two ways and corresponding techniques of increasing populations of this species have been suggested here, which will be able to provide reference for further carrying on conservation and expansion of population of Bretschneidera sinensis Hemsl.
