Culture medium of dendrobium candidum

Abstract

A culture medium of dendrobium candidum is composed of pine bark, bagasse and camellia oleifera bran, and is fermented with an EM strain. The culture medium composed of pine bark, bagasse and camellia oleifera bran is very suitable for growth of dendrobium candidum. Without addition of a chemical fertilizer, yield of dendrobium candidum can be guaranteed. Flaky and blocky pine bark is slowly converted into subsequent nutrients, thus forming a long-acting and balanced nutrient supply system. Meanwhile, blocky substances are distributed in the medium, thus making the medium to be loose and being beneficial to root system growth of dendrobium candidum. Camellia oleifera dregs have high fertilizer efficiency and are a natural plant-source ecological pesticide with advantages of no pollution, no residual toxicity, tolerance to storage, durability and long pesticide effect. With the application of camellia oleifera dregs, fertilizer efficiency of the culture medium is greatly enhanced, long-acting insect prevention of the culture medium can be realized, the culture medium has no pollution or residual toxicity, and a dendrobium candidum product with high yield and high quality can be cultured.

Description

technical field [0001] The invention relates to a new technical field of preparation of a plant cultivation substrate, in particular to a preparation method of a cultivation substrate of Dendrobium officinale. technical background [0002] Dendrobium officinale is the second largest genus of herbaceous plants in Orchidaceae, mainly distributed in tropical and subtropical virgin forests and similar warm and humid areas, often epiphytic on limestone or trees of bryophytes. [0003] Dendrobium officinale is a commonly used rare and precious traditional Chinese medicine, listed as the first of the nine immortal herbs in China, and has a long history of application. Listed as the top grade in "Shen Nong's Materia Medica", it has the effects of nourishing yin and clearing heat, promoting body fluid and benefiting stomach, moistening lung and relieving cough, moistening throat and improving eyesight, and prolonging life. At present, the average market price of fresh products of De...

Problems solved by technology

After multiple analysis, the slow growth rate and low yield of Dendrobium candidum are mainly related to its cultivation medium.

At present, the most widely used substrate for the cultivation of Dendrobium candidum is the use of pine bark as the substrate, and pine bark has a tough fiber structure, which is not easy to rot and cannot transform nutrients, so its fertilizer efficiency is very low, which eventually leads to slow growth of Dendrobium candidum ,Low Yield
