The grafting of flowers and trees can not only maintain the excellent characteristics of the female parent, but also make up for the defects of certain parts of the bonsai, meet the need of modeling, and greatly shorten the production time of the bonsai, which is widely adopted by the family. However, grafting requires high technology and carelessness. If grafting does not survive, it will not only fail to achieve its purpose, but will also destroy the original bonsai. The technology of improving the grafting survival rate of flowers and trees is summarized as follows: 1. The grafting season of the selective grafting season varies depending on the scion used for grafting. Branches are mostly carried out in the spring. Generally, it is best when rootstock sap begins to flow. Buds can be grown during the entire growing season of flowers and trees. It is best when the rootstock peels easily. Second, pick up the rootstock and cuttings selection and processing The tree species with strong affinities have strong affinity for rootstock rootstock cuttings, which is the premise and basis for grafting survival. Affinity is not strong, and the ability to produce healing tissue between rootstock and scion is weak, new delivery tissues are difficult to form, water and nutrients are not delivered, and grafting fails. Therefore, the grafting of this anvil is generally selected in production. In addition, other tree species with strong affinity are also selected as rootstocks, such as black pine as the rootstock for five-pin pine, peach and plum as rootstock, and kumquat as rootstock, water wax and privet. Do osmanthus rootstock, etc. If no other requirements are required, young rootstock is the best choice. Because in this period, its vitality, strong growth potential, it is easy to form a healing organization. If you want to quickly make old pile bonsai, you can only choose the old pile as rootstock. 2. The selection and treatment of cuttings is best to select strong and strong growth shoots as the cuttings on young trees that grow vigorously and have no pests and diseases. For budding, new shoots of the original shoots are used to pick and pick them. Buds can also be harvested from buds of one-year-old shoots during the dormant period, but grafting with this woody bud must be kept fresh under low humidity conditions. For branching, fully lignified or semi-woody branches are used for scioning, followed by picking. To harvest cuttings in the field, we must earnestly do a good job of keeping fresh and moisturizing the cuttings. Can be used wax seal cuttings base, wet sand buried, spray, cellar storage and other methods. Third, strictly according to the requirements of grafting operation that is in the grafting process to achieve "fast, flat, accurate, tight." "Fast" means that the grafting knife must be sharp and the grafting action should be quick. Minimize the drying time of the splice noodles and the rootstock interface. "Flat" means that the splice noodles and the rootstock interface should be smooth, and there should be no bumps so that the two can be tightly integrated." "Quasi-" is to align the scion and the rootstock when inserting the scion. This point is the key to the whole process of grafting. The formation of layers is misaligned and will never survive. “Tightness†means that the dressing of the anvil and the panicle must be tight, and looseness must not exist. Only when it is tight can it form a healing organization. Fourth, to create conditions to promote the survival of grafting weather is the best without windy sunny days. For tree species (such as plums and peaches) that have been damaged by bleeding, grafting should be carried out at a time when the bleeding is low, or the method of cutting water at the base of the rootstock should be adopted. The tree species secreting lipids (such as black pine) should be protected from resin secretion. During the vigorous period, grafting is performed during the slow period of resin secretion. During cutting, the turpentine on the cutter is wiped with alcohol, and the base of the scion is soaked in warm water at 40° C. to prevent the secreted resin from covering the cut, making the forming layer difficult to dock, and the temperature The tree species with high humidity requirements are grafted in the greenhouse. Fifth, after the management should be fine 1. The well-protected interface can be treated with plastic bags, sunshade, wax coating, burying on the heap, and binding with plastic strips to prevent the interface and scion from affecting the healing and survival. At the same time, we must prevent the interface from entering the water. 2. Clipping in time in the early spring budding, when grafting or when grafting survival when scraping, can stimulate budding germination, in the summer and autumn buds, Qin Chun anvil, is conducive to winter. A branch is connected, if the use of splicing, cutting, grafting, then anastomosis in grafting: If the use of abdominal grafting, abdominal skin grafted, can not cut the anvil, after grafting to survive and then cut the anvil. 3. After loosening and grafting for a period of time, it is necessary to loosen the plastic straps for bundling, so as not to hinder the growth of scions; but to loosen and not to abandon winds, or to prevent people from crashing. The scion buds and rootstocks were completely healed before they were released. 4. In addition to the survival of the grafting, the sprouts on the rootstock were all removed to promote new shoot growth. 5. If grafting is not successful, it must be promptly patched.
