Unorganized layering propagation method of wild roses

Abstract

The invention discloses an unorganized layering propagation method of wild roses. The method comprises the following steps of (1) layering time and branch selection, (2) seedbed and matrix selection,(3) layering operating and (4) post-layering management. According to the unorganized layering propagation method of the wide roses, propagation and seedling culture can be conducted in a period whencutting propagation or normal layering propagation cannot be conducted to increase chances of seedling-culture production so that the production rate can be improved; meanwhile, raw materials are saved, wherein only one bud is needed to produce one seedling, so that the use ratio of seed tree branches is improved; the propagation method has the advantages that the seedling emergence rate is high,the preserving rate can reach 98% or above, the speeds of rooting and germination are high, and operation is simple.

Description

technical field [0001] The invention belongs to garden seedling cultivation, and in particular relates to a method for in vitro layering propagation of wild roses. Background technique [0002] The seedlings produced by using the wild rose isolated layering propagation method can maintain the inherent characteristics of the species, can realize rapid propagation in a short period of time, is easy to operate, simple in method, high in survival rate and high in preservation rate. It meets the requirements of "many, fast, good, and economical" production of landscaping seedlings that are advocated today, such as low consumption, high output, saving materials, and reducing waste of data sources. The seedlings produced can be used as grafting rootstocks for roses, etc. For greening purposes. [0003] At present, wild rose cuttings are the main method for seedling propagation. Hard branches (before the lignified branches germinate in early spring) or tender branches (when the bra...

AI Technical Summary

Problems solved by technology

[0003] At present, wild rose cuttings are the main method for seedling propagation. Hard branches (before the lignified branches germinate in early spring) or tender branches (when the branches are semi-lignified in May-June) are often used for cuttings, and the seedlings are greatly restricted by the season; Parts often need to be treated with rooting agents to promote rooting, which is cumbersome to operate and will increase the cost of seedling cultivation; and because each cutting has two cuts, the cuttings are easily attacked by pathogens, resulting in failure of seedling cultivation or a decrease in survival rate

[0004] The conventional layering method is also more common. The operation method: after the leaves fall in autumn, pull the branches that are not separated from the mother plant to the ground, bury them in the soil at a certain depth, and after a growing season, after the new plants have roots and stems, dig them out at the appropriate time. Separate the mother plants one by one and plant them separately. This method takes a long time to raise seedlings and has a relatively small reproduction coefficient.

In addition, this method can only be used on the branches of the mother plant at a low position, and the branches growing at a high place are not easy to be layered. Moreover, the area around the mother tree suitable for layering is limited, so the utilization rate of the branches of the mother plant is relatively low.
