Grafting technique of embedded Bud of Pear Tree

Due to the physiological characteristics or improper management of pear varieties, pear main branches (dry) bare legs, resulting in inner and outer density, thin and weak fruit branches, ineffective consumption of nutrients, small fruit, poor quality and low yield. In order to solve this problem, after several years of practice and exploration, we adopt the methods of embedded bud grafting and hard branch grafting in spring, summer and autumn, which effectively solve this problem, and it is simple and easy.

1. Before the pear tree sprouts in spring

On both sides (upper side) of the bare leg branch (stem), one scion (the same variety or other varieties) is alternately grafted every 20 cm. Scion cutting leaves 2-3 buds, preferably a mixture of leaf buds and axillary flower buds. The germinated branches of leaf buds and axillary flower buds should not grow excessively, and they are easy to form fruiting branches. The grafting method is drilling, skin grafting or ventral grafting of twigs.

February and July

Bud grafting or subcutaneous grafting is carried out in the parts where the bare leg stem (branch) needs the fruit branch. Smear the surviving buds or carve buds on top of the buds before sprouting next spring to promote them to sprout and branch.

3. Late September to early October

The grafting method is basically the same as that in spring, but it is better to use axillary flower buds in scions.

Branches with axillary flower buds are used as scions in spring, summer and autumn, and do not use long branches as scions as far as possible, so as to prevent new branches from forming bare legs again.

In addition, for the empty-bore tree whose fruit moves outward, using the overgrown branch on the bare-legged branch to cultivate the "dragon turning back" fruiting branch is to pull the overgrown branch on the bare-legged tree back to the position of empty bore and no branch, and cultivate it into fruiting branch year by year. Finally, the balance of tree potential, hanging fruit, stable yield, high yield, positive fruit and good quality were realized.

For tree species with angular or furrowed branches, such as Chinese chestnut, jujube, or other plant materials, embedded bud grafting is used when the rootstock and ear are difficult to leave the bark.

1. Pick up the buds

The buds on the scion are cut from top to bottom. First cut downward oblique from the upper 1.5~2cm of the bud with a little xylem, and then cut horizontally at 1 cm below the bud to remove the bud slice.

2. Cut the rootstock

At the selected height of the rootstock, take the smooth side of the shade and cut a section equal to the length and width of the buds from top to bottom with xylem. Cut off the upper part of the bark with slightly xylem and leave 0.5cm in the lower part.

3. Cutting scion

Insert the bud into the incision to align the cambium, then stick the remaining part to the bud and tie it with a plastic strip.
