Description

Technical Field

[0001] The invention relates to the technical field of Weigela cultivation, and in particular to a Weigela grafting cultivation method. Background Art

[0002] Weigela is cold-resistant to minus twenty degrees Celsius and heat-resistant to about 40 degrees Celsius. It is a hardy, easy-to-grow and highly ornamental plant. However, the Weigela plants cultivated in the prior art are either tall Weigela trees or colorful Weigela trees with sparse and single-color flowers, which are not beautiful enough and have low ornamental value, or miniature Weigela plants with bright and abundant flowers, beautiful flower shapes and high ornamental value, but the plants are small and not tall enough. Therefore, the present invention proposes a grafting cultivation method for Weigela that can cultivate Weigela plants that are both tall and beautiful. Summary of the invention

[0003] In order to overcome the technical defects in the prior art and effectively solve the technical problems in the background technology, the present invention provides the following technical solutions:

[0004] A grafting cultivation method for Weigela floridula, characterized in that it comprises the following steps:

[0005] S1: Cultivate and select Weigela trees with a diameter of 5-10 cm and a plant height of 1.5 meters. Use grafting shears to cut off the lignified branches at a height of 1.2 meters, flatten the cross section with a grafting knife, and split it 2-5 cm downwards at 1-2 cm from the edge of the cross section with a grafting knife;

[0006] S2: selecting a miniature weigela flower that needs to be grafted and cultivated into a tall tree, using a grafting shears tool to cut the required branches from the miniature weigela flower, and using a grafting cutter to cut the lower end of the branch into a wedge-shaped horse ear shape;

[0007] S3: insert the lower ends of the miniature Weigela branches obtained in S2 into the split part of the branches of the Weigela tree in S1, aligning them layer by layer in a square shape;

[0008] S4: Use the grafting film to wrap the area where the connection in S3 is completed from bottom to top tightly;

[0009] S5: The grafted plants in S4 are cultivated under a suitable temperature and humidity environment to obtain the desired Weigela plants.

[0010] As a preferred technical solution of the present invention, the branches cut in S2 need to keep 2-4 cm at the bottom of the bud eye and 1-2 cm at the top of the bud eye.

[0011] As a preferred technical solution of the present invention, the grafting film in S4 is glutinous rice paper.

[0012] As a preferred technical solution of the present invention, the grafting pruning tool is a pair of pruning shears.

[0013] As a preferred technical solution of the present invention, the grafting tool is a utility knife.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the grafting cultivation method of the weigela is reasonable and practical, easy to operate, and can quickly and efficiently cultivate various weigelas with tall plants, beautiful flowers and high ornamental value, which can well meet people's ornamental needs. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be further clearly and completely described below. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Embodiment 1:

[0017] Grafting during the green leaf stage: Use pruning shears to cut the lignified part of the colorful weigela branch with a diameter of about 5 cm from a height of 1.2 meters, then use a utility knife to flatten the section, and then use a utility knife to split the middle of the section 3 cm downward at 1 cm from the edge of the section, cut a section of woody flower branch from the miniature weigela, keeping it about 3 cm below the bud and about 1 cm from the top of the bud, cut the lower end of the bud of the scion into a horse ear-shaped wedge, and then insert it into the split colorful weigela branch, aligning the layers with a side, and finally wrap it tightly with glutinous rice paper from bottom to top. The wound will heal in about half a month.

[0018] Embodiment 2:

[0019] Grafting technology during the deciduous period: Use pruning shears to cut a lollipop high-stem Weigela tree with a diameter of about 5 cm from a height of 1.2 meters, flatten the cross section with a utility knife, and split it down about 3 cm long with a utility knife at 1 cm from the edge of the cross section, then cut a branch from the miniature Weigela and leave a bud, keep the lower end of the bud about 2 cm and the top of the bud about 1 cm, use a utility knife to cut the lower end of the scion into a horse ear-shaped wedge, and then insert it into the split place of the colorful Weigela, aligning the layers with one side, and finally wrap it tightly with glutinous rice paper from bottom to top. Callus tissue will grow in a warm and moisturizing environment. When the temperature rises in spring, the bud will break through the glutinous rice paper and grow normally. After a summer of growth, it will be a new type of Weigela landscape tree with a crown width of about 1 meter.

[0020] In addition, after repeated grafting experiments, the grafting and cultivation method of the weigela of the present invention is suitable for the entire growth period, green leaf period and leaf fall period of the weigela plant, and can be used for grafting and cultivation using a variety of grafting methods such as cutting grafting, bark grafting, bud grafting and branch grafting. It is not limited to the branch grafting method shown in the above embodiments, and the survival rate is relatively high when various grafting methods are used in the above periods.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
