目前,有些果园和各家各户栽植着不少西伯利亚杏树,品质低劣,产量不高,经济收益低,采用高接换头技术,把大杏树树冠更换上绥棱红和吉林六号李子,嫁接成活率高,形成树冠快,枝条发育良好,当年枝条多数能形成花芽,换头后第二年嫁接枝都有产量,第三年平均每株结李子44斤,最多一株结370斤。自七○年进行高接换头,证明在5～20年生大杏树上都可进行,是一项切实可行,群众乐于接受的技术措施。
At present, some orchards and various households planted a lot of Siberian apricot trees, poor quality, low yield, low economic returns, the use of high interchangeable head technology, the canopy of the giant apricot tree on the Sui edge red and plum Jilin VI , The graft survival rate is high, the formation of canopy fast, well-developed branches, when most of the branches can form flower buds, the second year after the head exchange grafting have yield in the third year an average of 44 pounds per crested plum, a maximum of 370 jin. Since 1970, the high pick-up, that in 5 to 20 years can be carried out on the apricot tree, is a practical, the masses are willing to accept technical measures.
