In the spring, the pear tree is highly connected to flower buds. Although the survival rate of pear trees is high, the fruit set is poor. The high flower buds in the autumn can not only update the varieties but also ensure the fruit set in the following year. Now we will introduce the high-rising technology of pear flower buds in autumn as follows: In the autumn, usually from late October to early November, pears will receive flower buds. Grafting prematurely, flower buds are not sufficient, and it is easy to branch and flower; grafting is too late, the temperature is too low, and the interface is difficult to heal. The scions should use medium and long branch flower buds on the trees of fine varieties during fruiting period. Branches are 0.5-l cm long and 10-20 cm long. Flower buds should be full and full. Grafting is generally adopted by grafting. Scallops were cut into two shorter sections. The long section was about 3 cm long, and the short section was about 1 cm long. It was wedge-shaped. The anvil was selected to be slightly thicker than the 1-3 year-old peripheral branch of the scion, not to be cut off, smooth from near the base. One side of the knife is cut longitudinally and is 3-5 cm long. It is about 1/3 of the xylem of the rootstock, so that it can be adapted to the size and angle of the cut surface. Then, insert the scion into one side of the anvil and insert the scion with the clamping force of the anvil. Then use a thin film to bind the joint from the bottom up to make the scion tightly connected to the rootstock and maintain the interface humidity. In practical applications, the number and location of grafts depend on the size of the tree and the planned yield. Generally, the adult tree yields 50-80 flower buds, and the yield per plant per year can reach 20-30 kg. If the tree is smaller or used mainly for pollination, it can be reduced to about 20.
