Example Embodiment

[0019] The following examples further specifically illustrate the technical solution of the present invention.

[0020] The present embodiment is a method for propagation of Cyclocarya spp. seedlings. The 1-year-old trunk or current-year-old branches obtained by cutting the stems or pruning in winter are used as propagation material. After being refrigerated at 0-4°C, it is carried out in early and mid-March. Hard-wood cuttings, after cuttings, keep the sand bed dry and the greenhouse moist until roots survive, supplemented with rooting agents, shading nets, and fertilization measures to obtain excellent clonal seedlings, specifically including the following steps:

[0021] 1. Branch pruning: In the middle of January, select the main stems of annual planting seedlings obtained during afforestation by cutting the stems. The thickness of the branches is above 0.5cm, and the cuttings are cut into lengths of 10-15cm. There are 2-3 full leaf buds on the cuttings, and the distance betwee...

Abstract

The invention relates to a cyclocarya paliurus seedling reproduction method, which is provided for solving the problems of long seedling cultivating time, low sprouting rate and seedling reproduction difficulties of the cyclocarya paliurus seedlings. The method is characterized in that trucks growing with one year or branches growing in the current year of the cyclocarya paliurus that are acquired by cutting trucks or branches for forestation in winter are used as reproduction material; after the trucks or branches are in cold storage with 0-4 DEG C, hard woods are cut in the early or middle of March; after cutting, a sand bed is maintained to be dry and a shed is maintained to be damp till the cuttings take root to survive; and auxiliary measures like rooting agents, sunshade nets and fertilizer are taken to the cuttings so as to acquire excellent clone seedlings. The material is obtained from local resources, so the resource utilization rate is high; the branches is maintained to be vigorous under low temperature and the germination of leaves of the branches is slow down, so the nutrient loss is reduced and the survival rate of the cuttings is high; and a warm damp environment is provided for the base parts of the cuttings to heal and take root, thus promoting the branches to take root and avoiding rotten roots.

Description

technical field [0001] The invention relates to plant cultivation techniques, in particular to a method for propagating pacarya paliurus seedlings. Background technique [0002] Cyanocarya ( Cyclocarya paliurus (Bata 1.) Iljinskaja) is a plant of the genus Cyclocarya (Juglaruiaceae) in the family Juglaruiaceae. It is a unique single-species plant in China and one of the endangered plants under national key protection. Studies in recent years have shown that Cyclocarya paliurus contains a variety of trace elements and chemical components that are beneficial to the human body, which can effectively prevent and treat diseases such as diabetes, hypertension, coronary heart disease, and neurasthenia. All in one rare tree species. [0003] Due to the poor development of Cyclocarya paliurana seeds, the natural renewal ability is weak, and the seeds have the characteristics of deep dormancy. Generally, it takes 2-3 years to germinate after sowing, resulting in long seedling time a...
