Preparation method of mulberry branch substrates for improving disease resistance of dendrobium huoshanense

Abstract

The invention discloses a preparation method of mulberry branch substrates for improving disease resistance of dendrobium huoshanense. The method includes the steps: (1) crushing and mixing paeonia ostii barks, paeonia ostii leaves and the like, adding water to boil mixture, adding EM fungicide to ferment mixture at constant temperature, treating the mixture to obtain biological matrix slag and liquid supernatant, and concentrating the liquid supernatant to obtain extracting solution; (2) taking mulberry branches, cutting the mulberry branches into sections, drilling the mulberry branches intohollow sections, uniformly drilling small holes in the side walls of the mulberry branch sections, immersing the mulberry branch sections into the extracting solution, adding mixed chemicals to hermetically boil mixture to obtain the boiled mulberry branch sections, and filling the boiled mulberry branch sections with biological matrix slag to obtain treated mulberry branch sections; (3) mixing humic acid, peat soil and the like, adding the treated mulberry branch sections and the extracting solution to ferment mixture in a pit, and adding pork liver powder and lobster shell powder to mix mixture to obtain initial fermentation mixture; (4) crushing gabbros, and leading in nitrogen to calcine the crushed gabbros to obtain modified gabbros; (5) mixing the modified gabbros and the like, adding the initial fermentation mixture and fine sand to mix and steam mixture, and drying the mixture to obtain high-resistance dendrobium huoshanense mulberry branch substrates.

Description

technical field [0001] The invention belongs to the technical field of ecological planting of Dendrobium huoshanense, in particular to a preparation method for improving the disease resistance of dendrobium huoshanense mulberry branch substrate. Background technique [0002] Huoshan Dendrobium, commonly known as Mi Huo, is one of the nine great fairy grasses in China. It is a herbaceous plant of the genus Dendrobium orchidaceae. In Huoshan County, the province, most of them grow in the crevices of cliffs and rocks surrounded by clouds and on towering ancient trees, or on tree trunks in mountainous forests and on rocks in valleys. Therefore, the wild Huoshan Dendrobium is very rare and can be compared to gold. The polysaccharides, amino acids, dendrobine and dendrobine contained in Dendrobium Huoshanense have curative effects such as improving the body's immune function, anti-cataract, anti-aging, anti-mutation and anti-tumor, and have high health care and drug development va...

AI Technical Summary

Problems solved by technology

The polysaccharides, amino acids, dendrobine and dendrobine contained in Dendrobium Huoshanense have curative effects such as improving the body's immune function, anti-cataract, anti-aging, anti-mutation and anti-tumor, and have high health care and drug development value. , but there are contradictions between it and the wild yield of Dendrobium Huoshanense and the protection of species. At present, artificial cultivation or imitation of wild environment planting methods are generally used to improve the development of Dendrobium Huoshanense; , Dendrobium Huoshanense has a high attack rate of pathogens and low survival rate, and the content of active ingredients in the planted Dendrobium Huoshanense is much lower than that of wild Dendrobium Huoshanense, resulting in high planting costs and low medicinal value
