Zelkova serrata field cutting propagation method

Abstract

The invention discloses a zelkova serrata field cutting propagation method which comprises the following steps of nursery land selection; soil and seedbed preparation; soil disinfection; cutting slip preparation; cuttage; management after field cuttage. According to field cuttage provided by the invention, by being compared with a facility cuttage, the processes of seedling exercising and transplanting are omitted, the cost for raising seedlings by cuttage is greatly reduced, so that the technology provided by the invention is more easy to master and popularize; in addition, the field cuttage method provided by the invention can stabilize the excellent characteristics of zelkova serrata through cutting propagation, and shortens a seedling period, nursery-grown plants grow uniformly, the requirements of forestation and afforesting on the quality and specification uniformity of the nursery-grown plants are met, the base parts of cuttings start to expand after cutting slips being cut for 30 days, adventitious roots generate at callused parts after one week, the rooting effect is good and the rate of survival reaches to 82 percent.

Description

technical field [0001] The invention relates to a field cutting propagation method of beech trees, which belongs to the field of plant cultivation. Background technique [0002] Beech is a rare and endangered tree species under the second-level key protection in my country. Deciduous trees, deep-rooted tree species, with well-developed main and lateral root systems, and strong wind resistance. It likes light, warm climate and fertile and humid conditions. It has strong adaptability, less pests and diseases, and long life span. The tree species can be used for medicine, timber and greening. Beech wood is a precious hard and broad material with excellent material, which can be used as high-end furniture. The tree has a beautiful shape, a broad crown, dense and slender branches and leaves, early autumn leaf color change, and rich seasonal changes in leaf color. It is an important autumn color leaf tree species and landscape greening tree species in the Jiangnan area. [000...

AI Technical Summary

Problems solved by technology

At present, the propagation technology of beech is mainly based on sowing and reproduction. With the reduction and decline of provenance, seeds are often collected from remaining isolated trees or deformed mother trees in production, resulting in a decline in the quality of collected seeds.

Moreover, the variation of seedlings is large, which makes the growth uniformity of seedlings poor, resulting in greater differences in the growth of trees in the middle and late stages

In addition, there is an obvious phenomenon of large and small years in the beech tree, which also has a negative impact on the stable production of seedlings.
