It is difficult to produce medium and large-scale laurel bonsai in the north, but in recent years, many peasant farmers have used ash bonsai grafted with stumps to be very popular with bonsai enthusiasts. Although the ash and osmanthus are of different genus, they can be grafted to produce large-scale osmanthus plants in the same family. The practice of grafting sweet-scented osmanthus with white wax bonsai is now introduced to bonsai enthusiasts.
First, the material and cultivation of white wax
The ash tree Oleaceae genus Ash, deciduous trees, widely planted in our country. Hi sunshine, slightly shade-tolerant. Can be used sowing breeding, cuttings, ramets and bead breeding. The ash tree has strong germination power, high survival rate and fast growth, and is a good material for grafting and cultivating the laurel bonsai scene. The scrapped stumps can be used, or the stumps of white wax suitable for the production of bonsai can be purchased in the nursery, cultivated and shaped, and then the sweet-scented osmanthus can be grafted.
The selection of the white wax billet is the same as the selection of other bonsai pile blanks, and the selection of the billet that is suitable for making bonsai is good. After the excavation of the pile blanks, the large roots are cut off and the fibrous roots are retained. According to the requirements of the bonsai modeling, the necessary branches are left and the excess branches are removed. According to the conditions of the pile blanks, they are planted on the upper pot for 1 to 2 years. For example, the root of the pile is good, the thickness of the branches is appropriate, and the length of the branches is appropriate. The excavation can then be grafted on the pot. The time of excavation and potting is carried out after the early winter deciduous period and before the spring ash and osmanthus sap flow.
Second, grafting
The method of grafting is based on the connection method and the splicing method. It can be carried out in the north China from May to August. The best time is from the front to the three volts, and it can be maintained in the open air. Generally, it can be successful in more than two months. In late March, when the white wax and sweet-scented osmanthus began to sprout, they were placed in a sunny shed after grafting to prevent the wind from losing water. After grafting, the stumps will grow new shoots and they must be cut off in time to prevent consumption of nutrients. When it was discovered that the scion was dead, the dead scion should be cut off in time, new white wax shoots should be cultured, and the scion should be re-grafted. The connection method is higher than the survival rate by connection method, and it is better to grow. Osmanthus scion to select short branches, leaves the density of the species, so that the osmanthus branches compact, such as the use of long osmanthus branches, to be grafted to survive and grow some number of branches promptly hit the tip, control the height.
Third, maintenance management
The habits of white wax and osmanthus are different, and they both need to be taken into account in the management of conservation. Especially in winter management, slight missteps will be lost. There are two main problems in winter management: one is to ensure the temperature, and the other is to prevent wind. The osmanthus landscape grafted with white wax should be placed in a sunny shed at a temperature of not less than 0°C in the winter so that the grafted osmanthus is free from frost damage and wind, making it safe for the winter, but the temperature should not be too high and the ash tree stump will be too high. Osmanthus branches do not sleep. The time for spring sheds should not be too early, too early, and the air is too dry. Osmanthus twigs, especially the interface, will be affected. It can take a gradual approach to open the shed until it is fully opened.
