Summer grafting time is generally carried out from early July to late September. The grafting time is too early, the development of the buds is not full, and the degree of lignification of the scion is low. The grafting time is too late, the interface heals slowly and the survival rate is low. Grafting is to choose a jujube seedling with strong growth, no pests and diseases, and a base stem of 0.5 cm or more as a rootstock; cut out the growing branches with no disease and insect pests, full of buds, and lignified as the scion, with a diameter of 0.4 to 0.6 cm. Cut the leaves to leave the petiole; the scion is preserved. In order to facilitate storage and transportation, the scion can be cut into small pieces of 20~30 cm long, buried with wet sand or wrapped with wet linen bags, and timely watered. The grafting method adopts the method of rooting with germination. Firstly, the buds are selected on the rootstock to cross the knives, deep into the xylem, and then cut the 1.5-cm long "T" shaped interface from top to bottom; above the scion full buds 0.5 Cut a knife at a centimeter, deep up to 1~1.5 cm of wood. Use a knife to quickly cut the bud from bottom to top. The length is slightly shorter than the interface on the rootstock. The bud is attached to the "T" shaped interface of the rootstock to make the bud. The forming layer of the sheet is aligned with the forming layer of the rootstock (the top is aligned with one side) and is fastened with a plastic strip having a width of 0.5 cm. After grafting, manage the survival of the farm 15 to 20 days after grafting. If there is any survival, it can be replenished in time. In the spring of the next year, Chengli Miao cuts the anvil at 2~2.5 cm above the bud and removes the plastic strip to promote the survival and germination of the grafted bud.
