What are the methods of bud grafting of seedlings and flowers? how to operate?

As the name implies, bud grafting is to use an axillary bud as a scion, graft it on the branches of the rootstock, and then sprout new branches from this axillary bud, thus growing into a flower seedling.

Before budding, cut off the full and full branches of the current year from the reproductive mother plant, and the axillary buds above must be fully mature and not yet germinated. Cut off the leaves after picking, but you must keep the petiole and wrap it in a wet cloth to prepare for budding.

There are two commonly used bud grafting methods, which can be selected according to the physiological characteristics of different flowers and trees.

(1) T-shaped bud grafting is suitable for rose, peach blossom, plum blossom, cherry blossom and other Rosaceae flowers and trees, which are easy to peel in late summer and early autumn and can remove axillary buds. During this period, the axillary buds in the middle of the annual branches should be cut off for budding when the  capsule stalk dredged  Aster strong buds / p > during the period of metabolism. First cut a knife 3-4 mm above the axillary bud, deep xylem 2-3 mm, then push forward from about 6 mm below the petiole, cut to the horizontal knife edge in front of the axillary bud to stop the knife, and then take off the shield bud. As you pinch off the xylem inside the bud with your fingernails, the grafted bud contains moisturizing in the population. Then cut a T-shaped incision at the back of the stem of the rootstock 15 cm from the ground, and the size of the incision should be basically the same as the size of the bud. As the buds are inserted from top to bottom into the T-shaped incision of the rootstock, let the buds be contained in the cortex of the rootstock, so that the transverse incisions on the upper side of the two are consistent, and finally tied and fixed.

(2) embedded bud grafting the cortex and xylem of some flowers and trees are closely combined, so it is not easy to peel off, so T-shaped bud grafting can not be used, embedded bud grafting should be used.

The difference between embedded bud grafting and T-shaped bud grafting is that the former cuts off a whole skin according to the size and shape of bud grafts on the rootstock, instead of including the buds of the scion in the cortex of the rootstock like T-shaped bud grafting, but affixed to the xylem of the rootstock, so it is also called skin bud grafting.

According to the affinity between the bud and the rootstock, the cutting shape of the bud can be flaky, ring-shaped and shield-shaped respectively, and there can be no xylem in the bud. The size and shape of the peeling on the rootstocks must be consistent with the buds in order to make the cortical sections around them tightly embedded together, otherwise they can not be alive.
