Problems solved by technology

At present, the seedling raising technology of wintersweet is mainly asexual reproduction including division, seed, grafting and other technologies. However, division propagation is easy to cause damage to the mother plant, while seed propagation exposes the shortcoming of slow propagation. Regarding the grafting research of wintersweet, The prior art discloses the technology of docking and plugging, but the survival rate of the above-mentioned technology is low, and the technical requirements for laborers are high, which seriously affects the garden application and promotion of wintersweet

Embodiment 1

[0014] A method for grafting and growing seedlings of wintersweet is characterized in that the method comprises the following steps:

[0015] (1) The best time for grafting is when the new buds germinate to about 0.4cm in February. The scion variety should be Suxin wintersweet, and annual strong branches with strong growth, full development and full leaf buds should be selected. The rootstock is 2 to 3-year-old wintersweet, watered once before grafting, and cut off at 20cm from the ground;

[0016] (2) The grafting method adopts the inlay grafting method. Use a grafting knife to make a horizontal cut on the rootstock at a distance of 3 cm from the cut, and then make a diagonal cut at about 1 cm above the cut, remove the cut skin, and then place 1 cm above and below the buds of the scion. Cut obliquely, take the buds and quickly stick the buds on the interface of the rootstock. Pay attention to the tightness of the knife edge, then tie it up with binding materials, and then sea...

Embodiment 2

[0018] A method for grafting and growing seedlings of wintersweet is characterized in that the method comprises the following steps:

[0019] (1) The best time for grafting is when the new buds germinate to about 0.4cm in February. The scion variety is Xinkou wintersweet, and the annual strong branches with strong growth, full development and full leaf buds are selected, and it is better to pick them as they are picked. The rootstock is 2 to 3-year-old wintersweet, watered once before grafting, and cut off at 30cm from the ground;

[0020] (2) The grafting method adopts the inlay grafting method. Use a grafting knife to cut horizontally at a distance of 5cm from the cutting edge on the rootstock, and then make an oblique cut at about 1cm above the cutting edge, remove the cut skin, and then place 1cm above and below the buds of the scion. Cut obliquely, take the buds and quickly stick the buds on the interface of the rootstock. Pay attention to the tightness of the knife edge,...

Embodiment 3

[0022] A method for grafting and growing seedlings of wintersweet is characterized in that the method comprises the following steps:

[0023] (1) The best time for grafting is when the new buds germinate to about 0.4cm in February. For the scion species, choose small-flowered wintersweet, and choose annual strong branches with strong growth, full development, and full leaf buds. It is better to pick and graft at any time. Use 2 to 3-year-old wintersweet, water once before grafting, and cut off at 25cm from the ground;

[0024] (2) The grafting method adopts the embedded grafting method. Use a grafting knife to cut horizontally at a distance of 4cm from the cut on the rootstock, and then cut obliquely at about 1cm above the cut, remove the cut skin, and then place 1cm above and below the buds of the scion. Cut obliquely, take the buds and quickly stick the buds on the interface of the rootstock. Pay attention to the tightness of the knife edge, then tie it up with binding mater...

Abstract

The invention discloses a grafting and seedling raising method for wintersweet. The grafting method is a notch grafting method and comprises the following steps of: transversely cutting a position 3-5cm away from a pruning wound on an anvil by using a grafting knife, obliquely cutting a position 1cm above the cut, and removing the cut bark; obliquely cutting positions 1cm above and below a scion bud, quickly adhering the scion bud to a notch of the anvil, and avoiding a condition that the cuts are coadunate; and binding by using a binding material, sealing by using a wet mud pie, preferably coating the mud pie with plastic cloth or thick paper to promote the notch to be healed, and ensuring that a bud grows out of the sealing mud after 25 days. The notch grafting method is an important link of the invention, and by means of the great vitality of the scion bud, the activity of a cambium can be promoted, the healing process is quickened, the grafting healing rate of the wintersweet is 95-97 percent, and the final survival rate is 96-98 percent.

Description

technical field [0001] The invention relates to a method for grafting and raising seedlings of wintersweet. Background technique [0002] Wintersweet is a deciduous shrub of the genus Wintersweet, with straight branches, yellowish-brown skin, a plant height of up to 3m, and plump clusters, giving people a rough and solid feeling. The leaves are opposite, oval-ovate to ovate-lanceolate; the surface is rough and hairy, and the texture is hard and brittle, so the planting should be placed in a sheltered place to avoid dark brown markings and damage on the leaf surface caused by strong winds swaying and rubbing. Flower buds are born in the leaf axils of annual branches, covered with layers of scales on the outside; sepals and petals are usually not easy to distinguish; the outer petals of the petals are large and sallow in color, the inner petals are short and light yellow in color, and there are purple-brown stripes in the lower part of the petals . The peduncle is very short...
