Method for culturing of Armillaria mellea and rapid high-yield cultivation of Gastrodia elata by using wood sheets

Abstract

The invention provides a method for culturing of Armillaria mellea and rapid high-yield cultivation of Gastrodia elata by using wood sheets. The method comprises the following steps: selection of a mother Armillaria mellea strain, culturing of an Armillaria mellea stock, fabrication and culturing of a three-grade Armillaria mellea cultivar, preparation of new firewood and a cellar bed, and placement of the new firewood and sowing. According to the invention, the Armillaria mellea cultivar is cultured through the following steps: sawing a weed tree applicable to growth of Armillaria mellea into unpeeled wood sheets with a length of 9 to 12 cm and a width of 2 to 4 cm; by weight, preparing weed tree sawdust, wheat bran, white sugar and gypsum into a culture medium, placing the obtained culture medium powder onto the bottom part of a wood sheet bag, then vertically placing the wood sheets of the weed tree into the wood sheet bag, placing the culture medium powder onto the bag, tying the bag mouth, placing the wood sheet bag into a sterilization tank, and carrying out continuous sterilization at a constant temperature of 100 DEG C for 20 hours or above; and after sterilization is completed, placing the Armillaria mellea stock into a culture chamber, and carrying out culturing at about 20 DEG C for 40 days so as to obtain the Armillaria mellea cultivar used for cultivation of Gastrodia elata or Polyporus umbellatus. The method provided by the invention replaces conventional mushroom-sticks for direct co-cultivation of Gastrodia elata or Polyporus umbellatus, achieves that cultivation and harvesting are in a same year, realizes one-time cultivation and harvesting for a plurality of times, has high and stable yield of Gastrodia elata, and fundamentally solves the phenomenon of empty cellar.

Description

technical field [0001] The present invention relates to a method for artificially cultivating A. arbuscules with wood chips, and also relates to a method for rapidly and high-yield cultivating Gastrodia elata with the A. arbus. technical background [0002] A. is a kind of wood saprophytic fungus, the mycelium is white, and there is another kind of mycelium called mycelium, which is brown-red in color, and it will emit light like fireflies in the dark, whether it is A. wood chips or the second-level original species (solid), it will glow in the dark or at night when it is torn apart, and the fruiting bodies of the fungus Adenoides grow at a temperature of about 8-14°C between December and January, which are umbrella-shaped, brownish-yellow, edible, and also a kind of medicine. The fungus can cure: epilepsy, insomnia, headache, dizziness, numbness of limbs, coronary heart disease, high blood pressure, blocked blood vessels, quenching wind and calming liver, dispelling wind an...

AI Technical Summary

Problems solved by technology

The fungus strands of A. elata must be cultivated twice in the soil to mix and plant Gastrodia elata. The number of differentiations of A. elata is high, and the ability to infiltrate the seeds of Gastrodia elata is obviously reduced. As a result, the seeds of A. elata cannot be connected to the bacterium, which will lead to the death of the seeds of Gastrodia elata. The phenomenon of empty cellars is serious and the output is low

The disadvantages of the above method: First, it is time-consuming. It takes three years from cultivating old fungus sticks to harvesting Gastrodia elata, and it takes three years to cultivate Polyporus with old fungus sticks; , can only harvest Gastrodia elata once; third, the yield is low, and the transplanted old fungus sticks will contain viruses, bacteria and insects, resulting in a very serious phenomenon of Gastrodia elata empty cellar; fourth, the labor intensity is high, and it consumes a lot of time in the process of cultivating old fungus sticks. a lot of manpower and material resources
