1、 Grafting method

1. Branch connection: select stronger rootstocks, cut them 5cm away from the ground, and cut them on either side. Use the pruned Meimei branch, cut the bottom of the branch into a wedge, insert it into the rootstock mouth and align it, and finally bind it with plastic film

2. Budding: it needs to be carried out in the growing season. Trim the cortex of the rootstock into a "t" shape with a knife and uncover it on both sides. The scion should use the healthy middle bud, cut 1-2mm horizontally above the bud point, and cut the bud point from the cuttings longitudinally. Finally, insert the shield shaped bud into the cutting mouth of the rootstock, align them and wrap them with film

2、 Breeding method

1. Cutting method: the most suitable time for cutting is about October. Select branches with good growth and no diseases and pests. Such branches are easier to take root. Prepare a clean substrate, insert a hole in the soil with chopsticks, insert it and wait for it to take root

2. Layering method: from the crown or peripheral branches in good growth state, then bend it and bury it in the soil. Pay attention to avoid being blown by the cold wind. Finally, divide it after it takes root
