河北省蔚县松枝口公社永宁寨大队,是个浅山丘陵区,土层很厚,自然生长着很多山杏树,但产量低,品质差。为改变这种状况,1973年,他们进行山杏“高枝多头”接大扁试验,嫁接了4株大杏扁树,1975年产果100多斤,砸杏仁1.8斤,平均株产杏仁4.5两,而且仁质饱满、颜色鲜艳。在总结群众经验的基础上,1976年组成60人的嫁接队伍,分16个小组,共嫁接2,500株,计划到1980年将全大队1.2万株大山杏树,大土杏树全部改接为大杏扁和优良品质的水杏品种。改接的方法,主要是采用插皮接法,即先把大山杏树按原来分枝的高低顺序(从属关系)

In order to change this situation, in 1973, they carried out a large flat test of the apricot “tall branches and bulls” and grafted four apricot trees. In 1975, they produced more than 100 kilos, smashed almonds and 1.8 pounds, and the average yield of almonds was 4.5 and two , But also full of color, bright colors. On the basis of summing up the masses’ experience, in 1976, a grafting team composed of 60 people was divided into 16 groups and a total of 2,500 were grafted. It is planned that in 1980, 12,000 large-leaved almond trees and large earth-apricot trees will be replaced by large ones Apricot flat and good quality water apricot varieties.
