(1) "D" shaped bud connection is the main grafting period in autumn. When grafting, first select the spring windward surface where the rootstock is 5cm above the ground, and it is a smooth and unblemished part. First cut a “D†shape incision, and then pick the buds on the scion. When cutting buds, use a knife to cut into the xylem 1.5 centimeters below the bud. Cut about 2.5 centimeters vertically. Cut a knife from about 1 centimeter above the bud, and then remove the buds with your fingers. sheet. When plugging the buds, use buds to connect the shank to pick out the “D†shaped interface on the rootstock, and gently insert the buds from top to bottom so that the top of the buds aligns with the “D†shaped cuts, and finally use 0.5-1. The centimeter-wide plastic strips are tied from the bottom up.
(2) Inlay bud grafting method is also called with wooden bud connection method. It is characterized by its simplicity, high survival rate, and free from seasonal restrictions. It can be grafted all year round. Specific operation method: Grab a variety of buds when the scion, the first in the 0.8-1 cm above the buds cut down a knife to 1/3 of the xylem, about 1.5-2 cm, and then 0.5-0.8 cm below the bud Diagonally cut 30 to the end of the first blade and take out the woody buds. The cut shape of the rootstock is the same as that of the cut buds, but it is longer than that of the buds. Remove the shavings from the rootstock and insert the buds immediately. It should be noted that the upper end of the bud must be exposed with a line of rootstock cortex and finally tied with a plastic strip.
(3) The splicing method is mostly performed before sprouting in the spring and before germination. When grafting, first cut the rootstock at the grafting site and cut off the wound surface, and then cut a vertical cornice in the middle. Pick a section of 2-4 buds at the time of scion cutting, and cut 3-4 cm long noodles on both sides of the lower part. When cutting, the outside should be slightly thicker, the inside slightly thinner, and the knife should be cut one centimeter away from the lower part of the shoot so as not to injure the bud. After cutting, face thickly outwardly and thinly inwards. Insert the scion into the root of the rootstock. Make sure that the scion layer is aligned with the forming layer of the rootstock. Be careful not to insert all the noodles. Leave about 0.5cm. White" is beneficial to wound healing. According to the thickness of the rootstock, 1-2 scions can be inserted. Afterwards, the interface is bandaged with plastic strips, especially root stock wounds, which must be wrapped so that water does not evaporate.
(4) The skin graft is also called the skin. The specific method is: First, in the grafted part, select the upper part of the rootstock from the smooth without injury and cut the wounded surface with a knife, then select a piece of scion with 2-4 buds. Holding a scion in one hand, holding a knife in the lower part of the top bud, cutting a noodles about 3-5 cm long, and then cutting the short noodles about 0.6 cm long at the back of the long noodles, then inserting the bark on the rootstock. Cut a vertical incision of about 2 cm, and then cut the scion and insert it into the long side of the cut. Also pay attention to the white space. After that, they are also fastened with plastic strips.
