葡萄育苗在北方寒地多以硬枝嫁接方法来培育嫁接苗。但由于某些原因,如砧木的过粗过细,砧穗比例计划失调等等.往往把剩余的接穗或砧木扔掉,实乃可惜。近年来发现,在生产中有的把剩下来的接穗妥善保管,不使芽眼萌动,剩余的砧木培育成自根苗,待6月份进行砧木绿枝嫁接,效果甚佳,嫁接成活率可达95％以上。而且生长旺盛,到秋季枝蔓成熟度也好,其效果超过一般硬枝接的效果。
Grape nursery in the northern cold and hard grafting methods to cultivate grafted seedlings. However, for some reasons, such as excessive stocking of rootstocks, imbalance of planted rootstocks, etc. It is a pity that often the remaining scion or rootstock should be discarded.

When the grafting of rootstocks and green branches takes place in June, the effect is very good and the grafting survival rate can reach 95% the above. And vigorous growth, to the branches in the autumn and maturity Ye Hao, the effect of more than the general effect of hard grafting.
