速生樱花大苗接穗切接操作为四步骤

速生樱花大苗接穗切接操作为四步骤

①砧木的准备。将砧木从圃地挖起,假 植于室内; 也可随挖随接,不必假植。根 颈 部1~2 cm粗的砧木比较适合进行室内切接繁殖,过粗过细都不易操作。进行 切接 时,将假植的砧木拔起,洗掉根部泥土, 留5~8 cm短截。我们有些嫁接师 傅采取 先嫁接后短截的方法,效果也很好。

②接穗和砧木的削法。在接穗下芽1 cm处削一长斜面,长约2~3 cm,在长面 的 对侧削一短面,长1 cm 以内。将接穗 剪成带有2~4个芽、长5~6 cm的小段。  将砧木的截口剪平,左手握砧木,右手于 砧木木质部的边缘(砧木断面的1/4~ 1/3 处)直切一刀,也可用两脚将砧木固定, 于砧木木质部的边缘向下直切一刀 ,砧 木切口的长、宽和接穗的长面相对应。然 后将接穗长斜面向着砧木插入, 并使一 边的形成层对齐,将砧木切口的皮层包 在接穗外面,准备绑扎。

③绑扎。用宽1 cm 左右的塑料薄膜 条(最好有一定弹性)加以绑扎在速生樱花大苗上,绑扎时 必 须将膜条拉紧。

④罩袋。接好后,将嫁接苗根部以 上罩上白色透明小塑料袋,并用包装绳 将口 扎好,这样可起保湿保温的作用, 利于樱花苗成活。小塑料罩袋的长宽尺寸约为 12 cm ×8 cm。 速生樱花大苗嫁接操作完成后就进入接后管 理阶段,接后管理对于嫁接来说是 相当 重要的,俗话说“三分接七分管”就是这 个道理

Fast-growing cherry seedlings cut grafting scion of four-step operation

① rootstock preparation. Dug up from the rootstock nursery, heel indoors; also available with the dug pick, do not heel. Root of the neck 1 ~ 2 cm thick rootstock are more suitable for indoor cutting grafting propagation, are too small and difficult to operate too thick. To cut the connection, it will be uprooted heel rootstock, wash the roots of the soil, leaving 5 ~ 8 cm stub. Some of us take the first master grafting method stub after grafting, the effect is also very good.

② scion and rootstock cut method. Under the scion bud at 1 cm cut a long slope, about 2 ~ 3 cm, cut the long side opposite a short face, long 1 cm or less. The scion cut with 2-4 buds, 5 ~ 6 cm in length pieces. The rootstock kerf cut flat, rootstock left hand, right hand on the edge of the xylem rootstock (rootstock section of 1/4 to 1/3) straight cutting knife, also used the rootstock feet fixed on the edge downwards rootstock xylem straight cutting knife, rootstock cut the length, width, and scion of a long face mapping. Then insert the scion rootstock long incline toward, and to align the side of the cambium, the rootstock scion wrapped in skin incision outside, ready banding.

③ banding. About 1 cm with wide plastic film strips (preferably with some flexibility) to be tied on the fast-growing cherry seedlings, the lashing of the membrane must be taut.

④ cover bag. Connected, it will more than cover the roots grafted white transparent small plastic bag and tied with packing rope to the mouth, so that moisture insulation can play a role in favor of cherry seedlings survived. Small plastic bags cover the length and width dimensions of approximately 12 cm × 8 cm. Fast-growing cherry seedlings grafted after the operation is completed after entering the access management phase, after the management received the graft is very important, saying "third pick seven in charge" is the truth
