How are jujube trees grafted?

How are jujube trees grafted? What good grafting techniques do jujube trees have? There are many grafting methods for jujube trees, such as split grafting, ventral grafting, peeling grafting, cutting grafting and tender shoot grafting. The planting network has sorted out the grafting methods of embedded buds of jujube trees, and the following detailed steps are listed for netizens' reference. Step 1, preparation of jujube grafting tools: jujube grafting requires pruning shears, grafting knives and plastic strips. Step 2, collection and preservation of jujube grafting scion: jujube spring and summer grafting: spring grafting scion is best prepared before the end of March, the first branch of one-year-old jujube with full development and free of diseases and insect pests is collected in the improved variety mother tree garden, the secondary branches are cut off (leaving 2 cm long), stored in a cool and humid place, buried with wet sand, and can also be stored in a cellar below 4 meters or hoisted into a well (below 7 ℃). In this way, the scion can be stored from late June to early July. Autumn grafting of jujube: autumn grafting can collect Lignification branches of the same year, remove secondary branches and leaves immediately, and use them whenever you pick them. If it needs to be stored for a short time, it can be inserted into a container containing 10 cm of water and lifted into the underground 0.5-1 m from the surface of the water or in the cellar. Step 3. Operation methods of jujube grafting: 1. Cut the buds of jujube trees with wood: cut off the original retained secondary branches and stumps 1-2 mm above the side buds of jujube trees with pruning shears, and remove acupuncture at the same time. When cutting buds, hold the branch above the main bud in one hand, hold a knife in the other, push the first knife from top to bottom at the intersection of the secondary branch and the primary branch, about 3.5-4 cm long, which is the long cutting surface; at 0.5 cm above the end of the first knife, cut the second knife horizontally downward to the junction of the first knife, with an angle of 30 degrees, this is the short cutting surface. If the jujube scion is too thick, sometimes longitudinal stripes will appear on the long cutting surface, which can be turned over and carefully cut off the protruding part to make the long cutting surface smooth. 2. The treatment method of jujube grafting rootstock: when grafted in spring and summer, cut the rootstock 20 cm from the ground to remove the secondary branches and acupuncture. In autumn, the secondary branches and needles below 20-50 cm below the lower part of jujube seedlings should be removed without cutting the anvil. Choose a straight and smooth surface at 10 cm from the ground of the jujube tree, hold the rootstock with one hand and push the first knife downward with the other, the length is slightly longer than the long cutting surface of the bud, and the width is the same as the bud, and then cut the second knife horizontally at 0.5 cm above the end point of the knife edge, the short cutting surface of the same scion. Get rid of the anvil. 3. Grafting operation: the sprouts of the jujube tree are quickly embedded in the incision of the rootstock to align the lower oblique mouth with the cambium on the left and right sides. Use a plastic strap with good elasticity, high tension and good softness to wrap it tightly from bottom to top to expose the bud part. Step 4, the management of jujube grafted seedlings: when the jujube head branch or jujube grows to 3-10 cm, cut the anvil 1 cm above the grafting bud and apply paint or wax to protect the wound. For jujube seedlings grafted in autumn, cut the rootstock in the spring of the following year. Other management techniques are the same as the general jujube seedlings. This method is suitable for nursery land, high grafting, wild sour jujube, excellent variety of jujube and so on.
