Problems solved by technology

Due to the growing scale of Dendrobium candidum tissue culture seedling cultivation, the demand for pine bark as a substrate is increasing day by day, which will inevitably lead to a large number of pine trees being cut down, resulting in an imbalance of the ecosystem and damage to the environment
In addition, Dendrobium officinale planted with pine bark as substrate is prone to root rot, soft rot, black rot and other diseases

Embodiment 1

[0021] A preparation method for dendrobium candidum cultivation granule matrix, comprising the steps of:

[0022] (1) According to the weight ratio, 48 parts of discarded edible fungus chaff, 6 parts of wood chips, 5 parts of Chinese herbal medicine waste residue, 3 parts of chestnut shells, 6 parts of peanut shells, 12 parts of mulberry stalks chopped into 1-5cm segments, and corncobs Mix the 6 parts evenly, add water until the water content is 65-75%, then add 200g of fermentation compound bacteria agent per cubic meter according to the volume ratio, and mix evenly, seal and accumulate fermentation at a temperature of 25-40°C, and spread it out to dry after the fermentation is completed After being pulverized into 20 mesh powders, the initial material A of the substrate is obtained;

[0023] (2) Spray the quicklime aqueous solution formed after the full reaction of 1.5 parts of quicklime and 37.5 parts of water by weight on the initial material A, stir evenly, pile up for ...

Embodiment 2

[0032] (1) According to the weight ratio, 45 parts of discarded edible fungus chaff, 6 parts of wood chips, 4 parts of Chinese herbal medicine waste residue, 5 parts of chestnut shells, 8 parts of peanut shells, 12 parts of mulberry stalks chopped into 1-5cm segments, and corn cobs Mix the 6 parts evenly, add water until the water content is 65-75%, then add 150g of fermentation compound bacterial agent per cubic meter according to the volume ratio, and mix evenly, seal and accumulate fermentation at a temperature of 25-40°C, and spread it out to dry after the fermentation is completed Finally, crush it into 5-10 mesh powder to obtain the primary material A of the matrix;

[0033] (2) Spray the quicklime aqueous solution formed after the full reaction of 1.0 parts of quicklime and 33.3 parts of water by weight on the initial material A, stir evenly, pile up for 3-4 hours to neutralize the acidic substances therein, and then spread out to dry until The water content is 28% to...

Embodiment 3

[0042] (1) According to the weight ratio, 51 parts of discarded edible mushroom chaff, 6 parts of wood chips, 4 parts of Chinese herbal medicine waste residue, 5 parts of chestnut shells, 6 parts of peanut shells, 10 parts of mulberry stalks chopped into 1-5cm segments, and corncobs Mix the 6 parts evenly, add water until the water content is 65-75%, then add 150g of fermentation compound bacterial agent per cubic meter according to the volume ratio, and mix evenly, seal and accumulate fermentation at a temperature of 25-40°C, and spread it out to dry after the fermentation is completed Finally, pulverize into 10-20 mesh powder to obtain the primary material A of the matrix;

Abstract

The invention provides a dendrobium officinale cultivation grain substrate and a preparation method thereof. The dendrobium officinale cultivation grain substrate is prepared from raw materials of, based on weight rate, 45%-55% of abandoned edible mushroom residue, 3%-6% of Chinese herbal medicine waste residue, 2%-5% of chestnut shell, 4%-8% of peanut shell, 10%-15% of mulberry stem, 4%-10% of corncob, 5%-8% of wood chip, 1.0%-2.0% of quick lime, 0.2%-1.0% of urea, 0.2%-1.0% of monopotassium phosphate, 0.1%-0.5% of zinc sulfate, 3.0%-7.0% of clay, 5%-10.0% of sod soil and 0.5%-1.0% of carbendazol wetting powder. The dendrobium officinale cultivation grain substrate can improve disease resistance of dendrobium officinale, and effectively reduces occurrence rate of diseases of root rot, soft rot and the like for the dendrobium officinale. According to the dendrobium officinale cultivated by using the dendrobium officinale cultivation grain substrate, survival rate can reach above 98%, the average plant height can reach up to 78cm one and a half years after the dendrobium officinale is cultivated, the average steam thickness reaches 7.5-8.2mm, polysaccharide content reaches 42.5%, and an average dendrobium officinale yield per mu can reach 580kg.

Description

technical field [0001] The invention relates to a plant cultivation substrate, which belongs to the technical field of plant cultivation, in particular to a dendrobium candidum cultivation granular substrate and a preparation method thereof. Background technique [0002] Dendrobium candidum, also known as black knot grass, is a traditional precious Chinese medicine in my country. It is a superior species in the Dendrobium family. It is known as "Thousand Golden Grass", "Plant Gold", and "Healthy Soft Gold". It is currently listed as a second-class by the country. Focus on protecting rare medicinal plant varieties. The medicinal parts of Dendrobium officinale are mainly fresh or dried stems, and its pharmacological effects have been recorded in ancient medical masterpieces such as "Shen Nong's Herbal Classic" and "Compendium of Materia Medica". Contains Dendrobium phenol, Dendrobium amine and rich trace elements. Modern clinical application and pharmacological research have ...
