Choose sunny weather, no wind or breeze grafting in the afternoon, when grafting, insert the bud into the incision of the rootstock, make the bud stick to the cortex of the rootstock, fasten it with a rope, and the seedlings can emerge in half a month.

(3) raising seedlings by cuttings.

Select more than two-year-old branches, cut into about 60 square meters, remove leaves, in summer and autumn cloudy and rainy days, insert into the wet seedling bed, 20-30 meters into the soil, compacted and watered, you can survive and transplant the following year.
