Problems solved by technology

Beech tree is solid and has big and small year phenomenon, and the germination rate of beech tree is 30~80%; Beech tree can also be propagated with branch cuttage, and hard branch, tender branch cutting rooting rate are 50~80% under the facility condition of moisturizing, heat preservation; Above-mentioned In the propagation method, affected by the size and size of the beech mother tree, the emergence rate of beech sowing seedlings is low, and seed propagation cannot maintain the original exce

Embodiment 1

[0019] (1) Selection and production of scions: In spring, on the healthy and ungerminated zelkova mother tree, cut the full-grown 1-year-old from the middle and upper parts of the canopy with vigorous growth, fullness, full dormant buds, and more buds. The branches are used as scions; cut the branches into 5cm long scions with 2 buds, and wrap them with a damp cloth for later use. Cut the scion from the back side of the bud position nearest to the lower incision, and when it reaches the xylem inwardly with a cutting knife, cut it down parallel to the central axis of the scion to the end. . spare;

[0020] (2) selection of rootstock and cut stock: select the 1.5cm seedling of zelkova 1-year-old ground diameter that grows vigorously, without damage by disease and pests to make rootstock; Cut off the rootstock at 3cm from the ground, flatten the section, and then go down at the center or edge of the xylem Cut straight, the width of the incision is equal to the diameter of the s...

Embodiment 2

[0024] (1) Selection and production of scions: In spring, on the healthy and ungerminated zelkova mother tree, cut the full-grown 1-year-old from the middle and upper parts of the canopy with vigorous growth, fullness, full dormant buds, and more buds. The branches are used as scions; cut the branches into 5cm long scions with 2 buds, and wrap them with a damp cloth for later use. Both sides of the base of the scion are cut into 3cm long wedges. spare;

[0025] (2) selection of rootstock and cut stock: select the beech tree that grows vigorously, do not have the 3cm seedling of ground diameter of 2 years to make rootstock; Rootstock is cut off at 4cm place apart from the ground, flatten section, then at the center of xylem or edge straight down Cutting, the width of the incision is equal to the diameter of the scion, and the depth reaches 3cm, and it should be cut with one knife. stand-by;

[0026] (3) Joining: Put the large cut side of the scion inward, insert it into the ...

Embodiment 3

[0029] (1) Selection and production of scions: In spring, on the healthy and ungerminated zelkova mother tree, cut the full-grown 1-year-old from the middle and upper parts of the canopy with vigorous growth, fullness, full dormant buds, and more buds. The branches are used as scions; the branches are cut into 6cm long scions with 3 buds, and wrapped with a damp cloth for later use. If the rootstock is thicker than the scion, both sides of the base of the scion are cut into 3.5cm long wedges. spare;

[0030] (2) selection of rootstock and cutting stock: select the beech tree that grows vigorously, do not have the seedling of ground diameter 4cm in 3 years to make rootstock; Rootstock is cut off at 5cm place apart from the ground, flatten section, then at the center of xylem or edge straight down Cut, the width of the incision is equal to the diameter of the scion, and the depth reaches 4cm, and it should be cut with one knife. stand-by;

[0031] (3) Joining: Put the large c...

Abstract

The invention discloses a method for raising seedlings of zelkova serrata by grafting. The method comprises the following steps: (1) selecting and making scions; (2) selecting and cutting a tree stock; (3) jointing; and (4) managing grafted seedlings. By adopting the method for raising the seedlings by grafting disclosed by the invention, excellent properties of a zelkova serrata stock plant such as ornamental property and the like can be maintained; and by adopting the mode of grafting on the stock, as affinity of the scions and the tree stock is high, healing rate is improved by 20-30% compared with the condition that the zelkova serrata is grafted on an ulmus pumila, and survival rate for nursery stock propagation reaches up to more than 85% and is improved by 20-50% compared with a method for raising the seedlings by cutting. Compared with cut seedlings, the grafted seedlings grow faster, and the plant has strong growth adaptability and strong stress resistance; and the method for raising the seedlings by grafting disclosed by the invention has the advantages of simple operation process, high reproduction coefficient and the like, thus the method has important significance of practice and popularization in propagation and production of nursery stock of the zelkova serrata.

Description

technical field [0001] The invention relates to a method for asexual propagation of plants, in particular to a method for grafting beech seedlings. Background technique [0002] Beech (Zelkova serrata (Thunb.) Makino) is an arbor tree species belonging to the genus Zelkova in the family Ulmaceae, and it is a national second-class key protected plant. The beech tree is tall and majestic, with dense green shade in midsummer and red leaves in autumn. It is an important landscape tree species. The propagation of zelkova is mainly based on seed sowing and seedling raising. Because the seeds of zelkova are small, the seedlings need to be sown on sandy loam soil with convenient drainage and irrigation, and spring is suitable for sowing. Beech tree is solid and has big and small year phenomenon, and the germination rate of beech tree is 30~80%; Beech tree can also be propagated with branch cuttage, and hard branch, tender branch cutting rooting rate are 50~80% under the facility co...
