Embodiment 1

[0016] Composition 1: 84% tea twigs, 14% bran, 1% lime, 1% gypsum

[0017] Weigh the tea tree twigs and bran according to the design ratio and mix them evenly, then weigh the lime and gypsum and mix them evenly with the previous mixture, and finally add tap water according to the standard of 55% water content of the substrate, mix well and put it into polypropylene The plastic bag was sterilized under normal pressure for 48 hours, and the pH of the matrix was controlled at 5.50-5.80 after sterilization. After sterilization, the bacteria bags are cooled and sterilized and inoculated, and then cultured at 22-25°C without light. During the cultivation process, the water content of the substrate is controlled at about 55% until the mycelium is covered with bacteria bags. After the germination is completed, the bacterial bag is perforated, and the formation of ear primordia is induced by temperature difference and light stimulation. After the ear stimulation is over, move the bact...

Embodiment 2

[0019] Composition 2: 50% tea twigs, 34% wood chips, 14% bran, 1% lime, 1% gypsum

[0020] Weigh the tea tree twigs, sawdust and bran according to the design ratio and mix them evenly, then weigh the lime and gypsum and mix them evenly with the previous mixture, and finally add tap water according to the standard of 55% water content of the substrate, mix well and put it in The polypropylene plastic bag was sterilized under normal pressure for 48 hours, and the pH of the matrix was controlled at 5.50-5.80 after sterilization. After sterilization, the bacteria bags are cooled and sterilized and inoculated, and then cultured at 22-25°C without light. During the cultivation process, the water content of the substrate is controlled at about 55% until the mycelium is covered with bacteria bags. After the germination is completed, the bacterial bag is perforated, and the formation of ear primordia is induced by temperature difference and light stimulation. After the ear stimulation...

Embodiment 3

[0022] Composition 3: 42% tea twigs, 42% wood chips, 14% bran, 1% lime, 1% gypsum

[0023] Weigh the tea tree twigs, sawdust and bran according to the design ratio and mix them evenly, then weigh the lime and gypsum and mix them evenly with the previous mixture, and finally add tap water according to the standard of 55% water content of the substrate, mix well and put it in The polypropylene plastic bag was sterilized under normal pressure for 48 hours, and the pH of the matrix was controlled at 5.50-5.80 after sterilization.

Abstract

The invention provides a composition for cultivating high-quality black fungus, which is composed of 84% of main materials and 16% of auxiliary materials. The main materials comprise tea branch shred and common wood chip, the auxiliary materials comprise 14% of wheat bran, 1% of lime and 1% of gypsum. The water content of the substrate can be controlled at about 55% after a siccative of the composition provided in the invention is uniformly mixed, the pH value of the substrate can reach to 5.50-5.80 after disinfecting by adding water. According to the invention, the black fungus quality can be improved by a special component in the tea branch shred. The substituted material is cheap and easy to obtain. The waste of the tea tree branch is taken as a substitute material due to the cost is almost free, and solves the problems of treating waste for tea growers. The quality of black fungus product cultivated by the composition is comprehensively enhanced, and is economical and environment friendly.

Description

technical field [0001] The invention belongs to the field of cultivation of black fungus as a substitute material, and in particular relates to a composition for cultivating high-yield and high-quality black fungus using a large number of discarded by-products of agricultural production as substitute materials, and is used for the cultivation of black fungus. technical background [0002] Black fungus is a kind of black, gelatinous and delicious edible fungus, which has always been a traditional export commodity in my country. It is mainly produced in the mountainous areas of Northeast China and Hubei, with an annual output of about 15,000 tons (dry ears). Black fungus, as a leader in edible fungi, is a black nutritional and health food that is favored by countries all over the world. [0003] The artificial cultivation of black fungus is initially to cut down trees in winter, remove branches, put them on the mountain field where black fungus grows, and allow them to be natu...
