Sowing and seedling raising method for bud seedlings of magnolia sieboldii through light-medium container

Abstract

The invention relates to a sowing and seedling raising method for bud seedlings of magnolia sieboldii through a light-medium container. The method comprises the following steps of seed pretreatment, lamination germination acceleration, land preparation and bed making, container specification selection, seedling raising medium preparation, medium filling and container placement, sowing and seedlingperiod management. The sowing and seedling raising method for the bud seedlings of the magnolia sieboldii through the light-medium container has the advantages that a container material and specification and a medium composition are suitable for cultivation of the magnolia sieboldii, and the emergence rate of the magnolia sieboldii is increased and can reach 90%; the root systems of the cultivated seedlings are developed, the seedlings grow robustly and have few diseases, and the growth vigour of the seedlings is good; meanwhile, cultivation management of the light-medium container bud seedlings of the magnolia sieboldii is normalized, the survival rate of the magnolia sieboldii is increased, the quality of the magnolia sieboldii seedlings is improved, and the production technology is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of plant sowing and seedling cultivation, and relates to a plant container sowing and seedling cultivation method, in particular to a method for sowing and seedling cultivation of magnolia magnolia light-substrate container sprouts. Background technique [0002] Tiannv Magnolia (Magnolia sieboldii), also known as Tiannvhua and mountain peony, is a small deciduous tree in the Magnoliaceae Magnolia. It is the only wild magnolia plant in Northeast China, and it is a national third-level key protected plant. It is listed as an endangered plant under national key protection in the "Chinese Plant Red Book". [0003] Propagation methods used in production include sowing, cuttings, grafting and so on. But its propagation speed is slow and the reproduction coefficient is low, and the afforestation or afforestation of bare-root seedlings is affected by the soil texture and the root damage of seedlings, often causing ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems of low reproductive coefficient and poor quality of seedlings in the prior art, the purpose of the present invention is to provide a method for sowing and raising seedlings of magnolia light substrate container buds, so as to realize that the container material, specification and matrix formula are suitable for cultivating magnolia magnolia, and improve Its emergence rate, growth amount, well-developed root system of seedlings, robust growth, less disease, and good growth
