Method for preparing dendrobium candidum culturing substrate by using conelike redpepper straw as main raw material

Abstract

The invention relates to a method for preparing a dendrobium candidum culturing substrate by using conelike redpepper straw as a main raw material. The culturing substrate is prepared from conelike redpepper straw, oil-tea camellia defatted cakes and corn cobs, wherein when the corn cobs are crushed, a screen mesh is not placed in a crusher, the corn cobs are crushed into irregular materials containing crushed materials, sheet materials and blocked materials. The culturing substrate which is prepared by using the conelike redpepper straw as the main raw material in combination with the corn cobs and the oil-tea camellia defatted cakes is very suitable for providing nutrients required for growth of dendrobium candidum, and a crushing measure of the corn cobs can realize the purpose that the crushed materials can be immediately converted into nutrients to be absorbed by the dendrobium candidum, while the sheet materials and the blocked materials are slowly converted into subsequent nutrients, so that a long-acting balanced nutrient supply system can be formed. Besides, the blocked materials are distributed in the substrate, so that the substrate is loose in texture, growth of multiple root systems of the dendrobium candidum is also facilitated, the growth rate of the dendrobium candidum is increased, and the yield is increased.

Description

technical field [0001] The invention belongs to the field of new technology for preparing plant cultivation substrates, and in particular relates to a method for preparing dendrobium candidum cultivation substrates by using chili pepper straw as the main raw material. 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.

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
