How many years does a grafted pear tree generally take to bear fruit?

The fruit of the pear tree is edible and has high nutritional and medicinal value. In China, the cultivated area and output of Chinese pears are second only to apples. Anhui and Hebei provinces are the concentrated production areas of Chinese pears, with the cultivated area accounting for about half and the output accounting for 80%, among which Dangshan County in Anhui Province accounts for about 1/3 of China's annual output. So, how many years does a grafted pear tree take to bear fruit?

1. How many years does a grafted pear tree take to bear fruit?

A grafted pear tree generally takes about 4 to 6 years to bear fruit. Because pear tree varieties are diverse and grafting methods differ, the time to bear fruit may vary.

2. Grafting methods for pear trees

There are relatively many grafting methods for pear trees, mainly including four methods: cleft grafting, plug grafting, side grafting and branch grafting.

1. Cleft grafting

Cleft grafting is carried out on branches with a diameter of 5-6 cm. First cut the rootstock horizontally to form a smooth cambium, then split it vertically with a grafting knife, cut the lower end of the scion into a wedge shape 2-3 cm long, insert the scion into the rootstock, and tie it tightly with plastic film.

2. Plug grafting

First cut away the cambium of the rootstock with a knife, then cut the scion into a horseshoe shape (cut away two-thirds of the outer skin on the back of the horseshoe shape). Then insert the previously cut scion into the rootstock, and finally seal it tightly with plastic film.

3. Side grafting

The best period for side grafting is from mid-September to mid-October. On bare parts of the pear tree, use side grafting to attach some branches, so as to form certain branch groups to fill the space and increase fruiting positions.

4. Branch grafting:

A grafting method that uses a section of branch with one or several buds as the scion is called branch grafting. According to different grafting methods, it can be divided into cut grafting, cleft grafting and side grafting, etc.

5. Cut grafting

The scion should retain 2-3 plump buds. Cut a straight flat slope 3 cm long at the lower end of the scion, and cut a 1 cm long slope on its back. Cut off the rootstock at 3-5 cm from the ground, choose a flat and smooth side, and cut straight downward slightly inward. It is best that the length and width of the cut are similar to the long cut surface of the scion. With the long cut surface facing inward and the short cut surface facing outward, insert it into the rootstock cut. At the upper part of the rootstock, expose 2-3 mm of the scion cut surface, align the cambium of the rootstock and scion on at least one side, and then tie and wrap tightly with plastic strips.

Generally, pear tree grafting does not use varieties from the same mother plant; it is necessary to adapt to local conditions and select excellent varieties that are suitable for the local area and have strong growth.
