It is suitable for grafting in late June. 7- 10 days before grafting, select exuberant peripheral branches and pick out the core to promote the early maturity of scion. When grafting, in addition to selecting full buds, the grafting site should be 5-8 cm higher than the ground, which is beneficial to the early germination of grafted buds.

Generally speaking, cutting seedlings germinate earlier than folding seedlings. But in summer, the rootstock must be cut off from the grafted bud by 3 ~ 5 cm, and several leaves should be left on the rootstock. After the grafted bud germinates, the rootstock should be cut at 65438±0cm above the grafted bud.

After cutting the rootstock, it is necessary to wipe the buds in time and wipe off all the buds on the rootstock, leaving only the grafted buds. Water the seedlings in time at the later stage. At the end of September, when the grafted buds grow to 70- 100 cm, all the buds are picked and watering is stopped to promote the growth and maturity of the seedlings and improve their overwintering ability.

Extended data

At this stage, the new shoots grow vigorously, and all the vigorous branches should be removed to ensure the light in the tree cavity and promote the fruit coloring.

At this time, the temperature in the shed should be controlled reasonably. The greater the temperature difference between day and night, the better the fruit coloring. At this stage, the skylight should be opened to reduce the temperature at night. During the day, the temperature is still maintained at 15℃~28℃, which shall not exceed 30℃, and the soil shall maintain a certain humidity.
