过去大山楂(Crat-aeguspinnatifida BgeVarmajor N.E.Br.)均以嫁接繁殖。为提高繁殖系数,缩短成苗时间,从1980年开始,对大山楂嫩花枝进行了三年扦插试验,取得了较好效果,扦插生根率达95.1%。现将结果介绍如下。
In the past, large hawthorn (Crat-aeguspinnatifida BgeVarmajor N.E.Br.) are grafted breeding. In order to increase the multiplication coefficient and shorten the time of seedling establishment, the cuttings of big hawthorn have been tested for three years since 1980, and the good results have been obtained. The rooting rate of cuttings reaches 95.1%. The results are as follows.
