Dendrobium officinale complex bacterial agent

Abstract

The invention belongs to the technical field of biological bacterial fertilizers and particularly relates to a dendrobium officinale complex bacterial agent. The complex bacterial agent is prepared by steps of separation and purification of in-root actinomycetes, screening of antagonistic actinomycetes, screening of mycorrhiza fungi growth promoting actinomycetes, determination of species status of the growth promoting actinomycetes and growth promotion of dendrobium officinale clonal seedlings by synergy of optimized mycorrhiza fungi and the actinomycetes. By synergy of dendrobium officinale mycorrhiza fungi and the in-root actinomycetes for obtaining the complex bacterial agent, dendrobium officinale cells can be stimulated to generate efficient defense capability, self repairing, disease resistance, extreme environment resistance of dendrobium officinale can be improved, the survival rate of the dendrobium officinale clonal seedlings is increased, growth of the dendrobium officinale clonal seedlings is promoted, and large-scale production of high-quality dendrobium officinale seedlings is supported technically.

Description

technical field [0001] The invention belongs to the technical field of biological bacterial fertilizer, and in particular relates to a composite bacterial agent of dendrobium officinale. Background technique [0002] Dendrobium officinale is a perennial epiphyte of the genus Dendrobium orchidaceae, which is widely used in research and development in the field of medicine. Modern medical research shows that Dendrobium candidum has medicinal effects such as nourishing the lungs and clearing heat, nourishing yin and nourishing the stomach, clearing the liver and improving eyesight, resisting cancer, and lowering blood sugar. As the best product for health care, Dendrobium officinale has been highly praised by medical scientists of all ages. [0003] At present, due to the low natural reproduction rate of Dendrobium officinale, strict requirements on environmental conditions, and long-term mining by farmers in production areas, natural resources are on the verge of extinction. ...

AI Technical Summary

Problems solved by technology

[0003] At present, due to the low natural reproduction rate of Dendrobium candidum, strict requirements on environmental conditions, and long-term mining by farmers in production areas, natural resources are on the verge of extinction.

However, because the seeds of Dendrobium candidum are tiny and have no endosperm, it is not conducive to obtaining large quantities of Dendrobium candidum seedlings under natural conditions.

At present, the Dendrobium tissue culture system has been successfully established, which can reproduce asexual seedlings of Dendrobium in large quantities, but there are problems such as low survival rate of transplanted asexual seedlings, slow growth, and long growth cycle.
