Embodiment Construction

[0022] Below in conjunction with embodiment the method of the present invention is further described.

[0023] A kind of cultivation substrate of Dendrobium officinale, the specific implementation method is as follows:

[0024] 1. Composition and ratio of raw materials: 49.8% pine bark, 40% bagasse, 15% camellia bran, 0.2% EM bacteria, appropriate amount of water.

[0025] 2. Raw material processing: first add the above-mentioned EM strains to an appropriate amount of water to obtain a bacterial liquid, then mix the above-mentioned pine bark, bagasse, and camellia oleifera bran and stir the mixed material evenly, and then mix the bacterial liquid and the mixed material again Stir evenly, and at the same time adjust the water content of the mixed material to 60-65%.

[0026] 3. Fermentation of raw materials: Pile up the mixed materials and ferment them for 25-30 days according to the conventional method to obtain the cultivation medium for production.

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...
