Problems solved by technology

[0003] At present, the charming rhododendron has been promoted and planted in most provinces of the country, but no large-scale and industrialized planting has been formed. The main reason is that most of the seedlings are propagated by sowing seedlings, but there are obvious disadvantages in sowing seedlings: large demand for seeds, long cultivation period, and poor growth. Problems such as slowness and inconsistent growth seriously restrict the development and utilization of charming rhododendrons
Tissue culture is still in the stage of laboratory research and development, with large investment, high technical requirements, long seedling slowing period, high cost of seedling cultivation, and it is impossible to form a large-scale seedling cultivation system
[0004] In summary, the problems in the prior art are: the sowing and seedling period of Charming Rhododendron is long, and the quality and quality of seedlings are inconsistent
Tissue culture is limited by technology and experimental equipment, and it is still in the small test stage, so it is not easy to promote

Abstract

The invention discloses a cuttage propagation method of rhododendron agastum for alpine greening, which comprises the following steps: preparation of a cuttage medium; preparation of a cottage bed; collection and pruning of cuttings; cuttage; and cuttage post-management. The cuttage propagation method solves the problem of large-scale reproduction of the rhododendron agastum by a cuttage propagation technology and adopting measures suiting local conditions according to natural conditions and climate conditions, and contributes to the application of landscape greening.

Description

technical field [0001] The invention belongs to the technical field of raising rhododendron charming, in particular to a cutting propagation method of rhododendron charming for alpine greening. Background technique [0002] Charming rhododendron is a newly developed ornamental tree species for gardens under alpine conditions, and its key seedling raising techniques cannot be ignored. At present, the commonly used technologies in the industry are as follows: one is sowing seedlings, and the technical process is as follows: collect mature rhododendron fruits in December or January of the next year, and place them in a well-ventilated place. Fall off, sieve and select, and seal the seeds in a dry place. Choose ventilated and fertile land for site preparation and make a seedbed, then sterilize the seeds with 0.5% potassium permanganate solution and rinse them with clean water, and then sow them in furrows on a well-leveled seedbed, with a seeding rate of 15kg per mu , covering...
