调查分析初花山楂幼树枝条生长与成花的相关关系,认为:首次成花的山楂幼树,单株结果母枝数量与枝量、枝条总生长量,以及上年剪留的甩放枝数量之间,呈极显著直线正相关:与枝条平均长度及枝条平均长度准标差之间,呈显著直线负相关。初花较多的幼树,其形态标志应是在良好生长的基础上,枝势差异相对缩小。在初花幼树上,25厘米以下的结果母枝占比例较大;大于30厘米的长旺枝,占总生长量的比重较大,但其成花较少,荫发当年不是成花的主要枝类,却是翌年大量成花的基础。
Investigation and analysis of early flowering hawthorn shoot growth and flower related, that: the first flowering of hawthorn sapling, the number of branches per plant and the amount of branches, the total growth of branches, There was a significant linear positive correlation between the average number of branches and the average length of branches and the standard deviation of the average length of branches. The early flowering saplings, the morphological signs should be based on good growth, the relative reduction of branch size. In the early flowering saplings, 25 cm below the result of the mother accounted for a larger proportion of branches; more than 30 cm long branches, accounting for a larger proportion of the total growth, but its less flower, shade that year is not a flower The main branches, but it is the basis for a large number of flowers the following year.
