The grafting of flowers and trees can maintain the excellent characteristics of the female parent, but the technical requirements for grafting flowers and trees are high, and carelessness in grafting cannot survive. The four key points that will improve the survival rate of grafted flowers and trees are described below: China Garden Network, May 16th News: The grafting of flowers and trees can maintain the excellent characteristics of the female parent, but the technical requirements for grafting flowers and trees are high, and carelessness can not be grafted. survive. The four key points that will improve the survival rate of grafting of flowers and trees are described below: 1. The grafting season for selection of quasi-grafting season flowers and trees varies depending on the scion used for grafting. Branches are mostly carried out in the spring, and it is generally best when the sap of the rootstock starts to flow; the buds can be carried out during the growing season of the entire flowers and trees, and it is best when the skin of the rootstock is easily peeled off. Second, it is necessary to optimize the affinity of tree species and cuttings for root stocks of rootstocks. This is the premise and basis for grafting survival of flowers and trees. If the affinity of the two is not strong, the ability to produce healing tissue between the rootstock and the scion is weak, new delivery tissues are difficult to form, water and nutrients are not delivered, and grafting fails. Therefore, generally choose the grafting of this rootstock, and other tree species with stronger affinity can also be selected as rootstock (such as black pine as the rootstock of pentaphylla, peach and plum as the rootstock of plum, and the rootstock of kumquat as the rootstock, water wax and privet. Do osmanthus rootstock, etc.). In general, young trees are best for stock selection. Because of its strong vitality and growth potential during this period, it is easy to form healing tissues. Third, it is best to properly handle the cuttings in the vigorous growth, no pests in the young female trees choose strong, strong growth branches as cuttings. For budding, most of the new shoots of the year's shoots are harvested, followed by picking; buds collected from the buds of annual branches collected during dormancy are also used for budding. However, grafting with woody shoots must be kept fresh under low humidity conditions. For branching, full lignified or semi-woody branches are used for scioning, and if cuttings are collected along with cuttings to the field, the preservation and insulation of the cuttings must be effectively performed (the base of the wax seal can be used. , wet sand burying, spray mist, cellar storage and other methods to properly handle).
