Problems solved by technology

[0005] However, the cuttage technology of beech hard branch and soft branch is still unsatisfactory in terms of utilization rate of cuttings, number of sources of cuttings and survival rate.
Moreover, most of the existing beech cutting propagation methods are seedbed cutting, land cutting or container cutting, and each cutting method has more or less problems in the utilization rate of seedling space, waste of substrate, low survival rate of transplanting, difficult cutting management and the impact of afforestation season. limit and other issues

Embodiment 1

[0030] 1Materials and methods

[0031] 1.1 Test materials

[0032] From the end of May to mid-June, the branches of the zelkova tree after the cutting of the mother tree were collected as cutting materials, and the same clone was selected for the cuttings; from early to mid-September in autumn, the target specifications were selected according to the results of summer cuttings. Twelve clones of different varieties were selected to test the survival rate of transplanting and the universal applicability of varieties.

[0033] 1.2 Experimental design

[0034] The single-factor experiment design was carried out on the position of the ears, the length of the ears, the diameter of the ears, the amount of leaves, the cutting method, the ratio of substrates, the types of hormones and the treatment time, as shown in Table 1.

[0035] 1.3 Cuttings

[0036] 32-hole forest tree plug cuttings with a diameter of 60×60mm, a bottom diameter of 20×20mm, and a height of 110mm were used, 128 plants (4×32 ...

Abstract

The utility model relates to a method for seedling growing by zelkova schneideriana twig plug cutting under the condition of full-light fog. The method comprises the following four steps: cutting preparation, cutting treatment, cutting, and cutting management and transplantation. Through studying the ear picking time, the ear picking position, the ear length, the ear diameter, the leaf number, a cutting mode, the matrix ratio, hormone species, the treatment time and other factors suitable for zelkova schneideriana twig plug cutting under the condition of full-light fog culture, a technical method which is efficient in ear utilization, large in quantity of annual seedlings produced, high in quality, high in transplanting survival rate and suitable for large-scale production management of zelkova schneideriana improved varieties is established.

Description

Technical field [0001] The invention belongs to the technical field of forest tree seedling cultivation, and particularly relates to a method for raising zelkova tree tender branches with full-light fog plug cutting seedlings. Background technique [0002] Zelkova is a large deciduous tree belonging to the genus Ulmaceae, and is produced in Central China, South China, Southwest China, the Korean Peninsula, Japan and other places. Zelkova has excellent wood properties, strong adaptability, drought-tolerant and moisture-resistant characteristics. It is a precious hard broadwood species with beautiful tree shape and rich seasonal changes in leaf color. It has high economic, landscape and ecological value. Zelkova trees grow slowly and are in great demand in the domestic and international markets. Large trees have been over-cut and endangered, and they are listed as second-level key protected wild plants by the state. [0003] Zelkova is difficult to collect seeds, and the genetic var...
