The time of mulberry grafting, how many days can confirm the success?

The time of mulberry grafting: grafting can be carried out in spring, summer and autumn. Confirm whether the grafting is successful: if the mulberry scion can sprout normally for more than 15 days, the grafting has survived; if the scion has lost water and dried up, the grafting has not been successful; if the wound has healed, but it has not yet sprouted, the rootstocks above the grafting interface can be cut off to promote scion germination.

First, the time of mulberry grafting

The main results are as follows: 1. Mulberry can be grafted in spring, summer and autumn. the level of mulberry grafting technology will directly affect the survival rate of mulberry after grafting. The general grafting methods are bag grafting, skin tearing root grafting, abdominal grafting, eye-digging grafting, bud grafting and so on.

2. The simple bud grafting method is widely used, during which a bud can be cut from the branch and then grafted on the rootstock. The advantage is that the scion is saved, the wound of the rootstock is small, it is easy to heal, and if there is no survival in one grafting, it can be regrafted.

2. Confirm whether the grafting is successful

1. If the mulberry scion can sprout normally for more than 15 days, it means that the grafting has survived; if it has not germinated about 50 days after grafting in spring, it is necessary to untie the plastic film and check the healing of the scion.

2. If the scion loses water and dries up, it means it is dead; if the wound has healed, but it has not yet sprouted, the rootstock above the grafting interface can be cut off, which is helpful to promote the scion germination.

3. Simple budding method of mulberry

1. Cut the buds

The main results are as follows: (1) the simple budding method is often used, first of all, the buds should be cut, the winter buds growing on the spike should be selected, and then the knife should be cut from 1 cm below the bud, and the angle of the knife and the spike should be 35 °smoothly cut into the xylem, reaching to the 1max 5 of the spike.

(2) from 0.5 cm above the bud tip, the angle between the knife and the scion is 20 °, cut smoothly into the xylem, up to the first cutting edge of the spike, and then remove the bud slices, generally require smooth cutting surface, can take a little xylem properly, the cutting surface should be clean, do not touch the sediment.

2. Cut the rootstock

Saw off the stump 10-15 cm from the ground, during which the saw should be smooth, then select the smooth part of the trunk, and cut it into a cut of the same size as the bud, with the same length.

3. Budding tablets

In general, after the rootstock is cut, the cut surface of the bud should be affixed to the xylem of the rootstock, and the upper end should be aligned with the incision of the rootstock. If the bud is too narrow, it should be aligned on one side, and if it is too wide, the two sides of the bud should be slightly cut off to make the bud adapt to the incision, so that at least one side of the cambium of the rootstock and the scion is aligned.

4. Bandage

After the bud piece is inserted, the prepared plastic film strip will be tied up from the bottom of the interface from the bottom to the top. When binding, the bud needs to be exposed until the interface section is all covered, and then tie the plastic film strip. However, pay attention to the binding of the graft interface should not leak air.
