阔叶树的嫁接一般是冬季休眠期采穗,砧木树液开始流动时进行嫁接。因山毛榉的自然生长地通常是内地高海拨地带,积雪量多,冬季采穗作业困难。为了解决这个问题,笔者在融雪后的初夏,采集当年生枝条作嫁接试验,并取得了一定的成果。1.材料接穗采自海拔650—700米处,积雪期12月上旬—4月下旬,采穗母树7株的树龄为100—150年生4株和50—70年生3株,前4株(编号1.2.3.4.)胸径分别为32.、37.5、40.0、37.0厘米。嫁接砧木为
Broadleaf tree grafting is generally winter dormancy ear harvest, rootstock sap flow began grafting. Due to the natural habitat of beeches is usually the mainland high-altitude areas, the amount of snow, winter earning difficulties. In order to solve this problem, the author in the early summer after the snowmelt, collecting branches for grafting experiment, and achieved some results. 1. Material scion taken from 650-700 meters above sea level, early December to early snow in December - late April, the spike 7 trees of mother trees of 100-150 years old 4 and 50-70 years old 3, the first 4 ( Number 1.2.3.4.) The DBH is 32, 37.5, 40.0, 37.0 cm respectively. Grafting rootstock for
