Pear tree grafting season months

The grafting time of pear trees is generally in spring and autumn, because its cambium is very active in spring and the survival rate will be high. In autumn, the leaves will slowly fall off, and the nutrients accumulated through photosynthesis will continue to loosen downwards. At the same time, the cambium layer is also relatively active, and the grafting survival rate will be equally high.

Pear tree grafting methods

There are many methods of pear tree grafting, including split grafting, splicing, abdominal grafting, and branch grafting. 1. Splitting method: Split branches with a diameter of 5-6cm. The rootstock needs to be cut transversely to form a smooth arc-shaped layer, then split longitudinally with a sterilized grafting knife, and the lower end of the cuttings is cut into wedges 2-3cm long. Insert the cuttings into the stock and tie tightly with plastic wrap. 2. Sealing method: First cut the scion into a horseshoe shape, then cut the rootstock into one layer, then insert the cut scion into the rootstock, and finally seal it with white plastic film. 3. Abdominal transplantation: Abdominal transplantation is best performed between September and October. On the bald part of the pear tree, some branches can be attached to fill the gaps in the plant and increase the fruiting part. 4. Grafting method: The grafting method using one or several bud branches as scions is called grafting. According to different grafting methods, it can be divided into cut grafting, cleft grafting and abdominal grafting

Precautions for pear tree grafting

1. Before pear tree grafting, insect control and weeding should be done to ensure that Easy to work when grafting. At the same time, all the twigs at the lower part of the rootstock should be cut off. 2. Regardless of whether the pear tree is grafted or not, you can touch the petioles of the grafted buds with your hands 7 to 10 days after grafting. If it falls right away, it's alive. If the petiole is scorched but does not fall off, reattach, inspect, and repair it as soon as possible. 3. The survival rate of pear trees is often low after continuous rain or drought after grafting. Management must be strengthened and watering and drainage as soon as possible can improve the survival rate. 4. After the pear tree is grafted, if the season permits, especially in southern provinces, the rootstock can be folded immediately, or 4-6 leaves can be left to cut the rootstock. After the grafted buds sprout and branch and grow 3-5 leaves, cut the rootstock twice at a distance of 0.5-1cm from the interface. If not, cut the rootstock once at 0.5-1cm above the interface, which will force the grafted buds to germinate and grow in the same year and leave the garden early. 5. The pear buds are relatively large, and the leaf pillows are also relatively large. The budding should be slightly thicker. When peeling buds, use your thumb to press the leaf pillow tightly and push it downward to prevent the bottom of the bud from sucking the heart and affecting its survival. 6. In the central and southern regions with a long growing season, fertilizer and water management must be strengthened. When the height of the pear seedlings is greater than 70cm, the core should be removed to promote the occurrence of secondary branches, increase the number of branches and leaves, and advance the shaping results. If the secondary branches and bottom corners are small, they should be opened. 7. After grafting the pear tree, pay attention when cultivating the soil and walking between rows to prevent the scion from shaking. Open the pile of soil as soon as possible after germination and loosen the soil as soon as possible after healing.
