影响悬铃木少球化嫁接改造后成冠因素的探讨

The study of forming crown factor of influence plan tree less-fruit-ballizing after graft and transformation

用生物统计的方法,对影响悬铃木少球化嫁接改造后成冠的几种因素进行了定量分析研究,结果表明嫁接后树冠恢复的快慢与两接穗品种、嫁接季节内嫁接时间的先后及嫁接枝数没有相关关系,而与砧木径级存在极显著的正相关关系.

The essay quantitatively analyses and studys the several forming crown factors of influencing plane-tree less-fruit-ballzing after graft and transformation. The result shows the speed of crown recovery is not inter related to the two grafting strains and the grafting time order. and the grafting branch number. but it obviollsly has the direct ratio relation wits tree stock annual ring.
