Embodiment 1

[0018] From winter to early spring, on the strong-growing, yet-to-be-sprouted eucalyptus mother tree, cut well-grown 1-year-old branches with a diameter of 1 to 2.5 cm and full dormant buds from the middle and upper parts of the crown as scions, and cut the branches into 15-2. 25cm, wrapped with a damp cloth; heat the container containing paraffin in a large container containing water, when the water temperature rises to about 100°C, immerse one end of the scion in the melted paraffin and take it out immediately, then turn it upside down and dip the other end, Cover the entire scion with a thin layer of paraffin wax, and then refrigerate it at a low temperature of about 5°C; in spring, when the eucalyptus seedlings have not germinated, cut the stored branches into 5cm-long sections. Scion, from the back of the bud position closest to the lower incision, use a cutting knife to cut inwards when reaching the xylem, then cut downwards parallel to the central axis of the scion to th...

Embodiment 2

[0020] From winter to early spring, on the strong-growing, yet-to-be-sprouted eucalyptus mother tree, cut well-grown 1-year-old branches with a diameter of 1 to 2.5 cm and full dormant buds from the middle and upper parts of the crown as scions, and cut the branches into 15-2. 25cm, wrapped with a damp cloth; heat the container containing paraffin in a large container containing water, when the water temperature rises to about 100°C, immerse one end of the scion in the melted paraffin and take it out immediately, then turn it upside down and dip the other end, Cover the entire scion with a thin layer of paraffin wax, and then refrigerate it at a low temperature of about 5°C; in spring, when the eucalyptus seedlings have not germinated, cut the stored branches into 8cm-long sections. Scion, from the back side of the bud position closest to the lower incision, when cutting inward with a cutting knife to reach the xylem, it is cut downwards parallel to the scion central axis to th...

Embodiment 3

[0022] From winter to early spring, on the strong-growing, yet-to-be-sprouted eucalyptus mother tree, cut well-grown 1-year-old branches with a diameter of 1 to 2.5 cm and full dormant buds from the middle and upper parts of the crown as scions, and cut the branches into 15-2. 25cm, wrapped with a damp cloth; heat the container containing paraffin in a large container containing water, when the water temperature rises to about 100°C, immerse one end of the scion in the melted paraffin and take it out immediately, then turn it upside down and dip the other end, Cover the entire scion with a thin layer of paraffin, and then refrigerate it at a low temperature of about 5°C; in spring, when the eucalyptus seedlings are about to germinate, they will be grafted on March 25, and the stored branches will be cut into 5cm-long sections for scion , from the back side of the bud position closest to the lower incision, when cutting inwards with a cutting knife to reach the xylem, it is cut ...

Abstract

The invention discloses a method for raising seedlings of golden bough goldenrain tree by grafting. The method comprises the following steps: (1) selecting scions; (2) storing the scions; (3) making the scions; (4) selecting and cutting a tree stock; (5) jointing or inserting; and (6) managing grafted seedlings. The method for raising the seedlings by grafting disclosed by the invention has the advantages that: firstly, the problem of difficult vegetative propagation of the golden bough goldenrain tree can be solved; secondly, excellent ornamental property of leaves and branches of the golden bough goldenrain tree is maintained, and the growth adaptability and stress resistance of the golden bough goldenrain tree are improved; and thirdly, seedling formation speed is fast, the tree stock is available, and only a small segment of branch is taken as one scion, thus propagation period is short, propagation coefficient is high and massive seedlings can be obtained. The method for raising the seedling of golden bough goldenrain tree disclosed by the invention has important popularization value in rapid propagation of the ornamental nursery stock of a goldenrain tree.

Description

technical field [0001] The invention relates to a method for asexual propagation of woody plants, in particular to a method for grafting and raising seedlings of eucalyptus eucalyptus. Background technique [0002] The golden branch eucalyptus is a variety of natural buds of the eucalyptus (Koelreuteria integrifoliola). Its new leaves are orange, and the autumn leaves are golden and brilliant. The winter branches are also golden yellow, which is of great ornamental value. In order to maintain the unique ornamental value of the golden branch eucalyptus, the seedlings must be bred by asexual propagation method. The cuttings and root cuttings of the golden branch eucalyptus are very difficult, and the reproduction efficiency is low. By grafting the eucalyptus into the propagation method of the eucalyptus as rootstock, it can maintain the excellent ornamental traits of the leaves and branches of the eucalyptus, improve the adaptability and stress resistance of the eucalyptus, sh...
