女贞和桂花都属木犀科,用女贞作砧木嫁接桂花嫁接苗的成活率高、生长迅速,当年苗高可达15～30厘米。 女贞嫁接桂花,最好在3月至4月中旬进行。也可在秋季9～10月嫁接。砧木选取一年生的健壮女贞,干茎粗0.6～O.8匣米:接穗选取1～2年生的健壮桂花枝条,芽要完整,不留叶片。嫁接方法,可用短枝搭接(块状切接法),也可用一般切接法或腹接法。其中以短枝搭接法操作较简便,接口愈合好,生长快、成活率高。 短枝搭接法的操作步骤:把砧木离地2～3厘米处截平,从截口向下连皮层削一刀,长2～3厘米;接穗取3～5匣米长。顶部留一牙,基部
Privet and Osmanthus are Oleaceae, with privet as a rootstock grafted osmanthus grafted seedlings survival rate is high, rapid growth, when the seedling height up to 15 to 30 cm. Primrose grafted sweet-scented osmanthus, preferably in March to mid-April. May also be grafted in the fall of September to October. Rootstock annual selection of robust privet, stem diameter 0.6 ~ O.8 box meter: scion selection of 1 to 2 years of robust sweet-scented osmanthus branches, shoots to be complete, leaving no leaves. Grafting method, available short stitch lacquer (block-cut access method), but also can be used to cut the general law or abdominal method. Which splinter lap method is more convenient operation, the interface healing, fast growth, high survival rate. Short branch lap method steps: the rootstock 2-3 cm off from the ground, cut from the cut to the skin cut a knife, length 2 to 3 cm; scion to take 3-5 box length. Leave a tooth on top, base
