Embodiment 1

[0018] This experiment provides a cutting propagation method of hornbeam tiantai, which mainly includes the steps of cuttings preparation, rooting treatment, substrate preparation and cuttings, rooting process management, transplanting and post-management, among which cuttings preparation includes material selection, pretreatment and storage , cuttings cutting and other links, the specific steps are as follows:

[0019] (1) Material selection: The parent trees of Hornbeam tiantai come from: a: ​​the native hornbeam plant of the type specimen in Huading Mountain, Tiantai County (about 70 years old); b: planted in Zhejiang Agriculture and Forestry University, Lin'an District, Hangzhou City, Zhejiang Province The 3-year-old seedlings of the roof hornbeam in the planting resource garden of the roof hornbeam. Cuttings were collected in late December 2017, late March and late May 2018, respectively. The 2017-year-old branches with no pests and diseases and vigorous growth were colle...

Embodiment 2

[0036] In order to further improve the rooting rate, this test was optimized on the basis of the best test plan based on Example 1 (i.e. collecting the current year's branches in winter, and refrigerated, soaked in NaOH solution, and soaked in rooting agent). Before taking, increase the step of branch activation, as follows.

[0037] (1) Material selection: The branches of the hornbeam are from the 5-year-old hornbeam seedlings planted in the hornbeam planting resource nursery of Zhejiang Agriculture and Forestry University in Lin'an District, Hangzhou City, Zhejiang Province. In late November 2018, we collected from the middle and upper part of the hornbeam mother tree in Tiantai, no pests and diseases, and vigorous growth branches of the year. The length of the branches was about 25-30cm, and 50 branches were neatly bundled in a cluster. A total of 2 bundles of 100 branches were placed in a container Bring back to the laboratory in a foam box on ice.

[0038] (2) Pretreatme...

Abstract

The invention discloses a cutting propagation method for Carpinus tientaiensis, and belongs to the technical field of forest tree breeding. The cutting propagation method is characterized in that thecutting propagation method mainly comprises the steps of cutting shoot preparation, root growth processing, substrate preparation, cutting, root growth process management, transplantation, later-period management and the like, wherein a cutting shoot is from a 3-5-year-old Carpinus tientaiensis seedling. According to the cutting propagation method, the technical problem that the Carpinus tientaiensis cutting is extremely difficult to grow roots can be solved. After measures, including seedling adoption, refrigeration, NaOH solution processing, rooting agent processing, seedbed warming and thelike, a great quantity of cutting shoots successfully grow roots and form seedlings, and after activating treatment is added, a cutting shoot rooting percentage and a planting percent are independently 83.31% and 80.67%.

Description

technical field [0001] The invention belongs to the technical field of forest tree breeding, in particular to a method for cutting and propagating the hornbeam of the roof. Background technique [0002] Roof hornbeam ( Carpinus tientaiensis ) belongs to the genus Hornbeam of the Betaceae family, arbor trees, up to 20 meters. Produced in Tiantai, born in mountain forests at an altitude of 800-1000 meters, Tiantai is the place of origin of the type specimen. Tiantai hornbeam is a unique endemic species in my country, which is of great value in the study of Betaceae flora and geographical distribution. Tiantai hornbeam has poor fruiting ability, obvious annual phenomenon, seed empty shell rate as high as 90%, and extremely poor natural regeneration ability. In addition to human destruction and habitat changes, there are currently less than 20 plants in the original place of Zhejiang Tiantai Huading Forest Park. It is in a critically endangered state and is now listed as a se...
