A kind of propagation method of magnolia officinalis with high yield

Abstract

The invention discloses a high-yield Magnolia officinalis propagation method, which relates to the technical field of plant propagation. The propagation process includes seed selection, seed treatment, selection and retention of female parent saplings, establishment of collection gardens, tree planting screening, and asexual propagation; it has a propagation process The invention has the characteristics of being simple, capable of breeding magnolia saplings with good resistance, increased weight of effective parts, and high active ingredient increment, and can be used for breeding high-yield magnolia saplings and other plants.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a high-yield magnolia bark propagation method. Background technique [0002] In the prior art, the selection and breeding of medicinal Magnolia officinalis seeds (seedlings) is mainly to select high-quality adult trees to collect mature seeds or to use the branches of the trees for cutting, grafting and layering for asexual reproduction. This breeding method is simple and easy to implement, but there are many shortcomings: the first is that there are few high-quality saplings, and the emergence rate is low, and the emergence rate is only 70%-80%, and the occupancy rate of high-quality saplings is only 30%-35%; The 2nd, saplings have weak resistance, and the disease susceptibility rate is more than 30% (mainly brown beetle cow disease and root rot); %-7%, only 11% in 10-15 years, and more than 13% in 20 years or more; Fourth, the output is low, every 666.7m 2 After the...
