山茱萸的花芽分化是年发育周期中的重要物候期,它与山茱萸的丰产稳产有密切关系。作者近几年研究结果表明:山茱萸花芽形态分化时间是在每年的五月下旬至九月下旬,其中六至八月为分化盛期,花芽分化与果实生长同步进行,两者在营养分配上的矛盾是产生大小年的主要原因之一。本文还研究了花芽分化的阶段,花芽分化与结实的多少,光照、土壤肥力等外界条件的关系,以及与其他物候期的关系,为进一步控制花芽分化提供了依据。
Dogwood flower bud differentiation is an important phenophase in the development cycle, it is closely related to the high and stable yield of dogwood. In recent years, the author’s research results show that the time of flower bud differentiation is between the end of May and the end of September each year, and the period from June to August is the period of differentiation. The flower bud differentiation and fruit growth are synchronous. Conflict is one of the main reasons for the size of the year. The paper also studied the stages of flower bud differentiation, the relationship between flower bud differentiation and the number of seedlings, light, soil fertility and other external conditions, as well as the relationship with other phenophase, which provided the basis for further control of flower bud differentiation.
