Formula of culture material for cultivation of auricularia polytricha and preparation method thereof

Abstract

The invention discloses a method for preparing an auricularia polytricha cultivation material by using branches and wood chips which are abandoned during trimming and felling of fast-growing forest belts and green forest belts as main raw materials. According to the invention, branches, wood chips are firstly crushed into bean-size particles; branches, wood chips, wheat bran, pig manure and the like are weighed in proportion and then uniformly mixed; and water is added while stirring is carried out so as to make moisture content of the mixture is 60%-65%. Generally, water addition for each 100kg of a dry material is 120-150kg and is specifically dependent on natural moisture content of the culture material. The standard is as follows: it is suitable when a small handful of the mixed culture material is rolled by hands into a ball and the hands have a certain moisture; if there is water droplets between gaps of fingers, moisture is too much; and if there is no water stain, moisture is insufficient. After piled up, the stirred culture material is covered with a plastic film and fermented for 2-3 days. During the fermentation process, the culture material is turned over once each day so as to avoid anaerobic fermentation. After the fermentation, the culture material is prepared and bagging can be carried out. The auricularia polytricha culture material prepared by the above method has advantages of comprehensive nutrition, low cost and wide source. In addition, sterilization is thorough, and auricularia polytricha is not easy to be infected by other bacterium; and hyphae absorb the material and grow better.

Description

Technical field [0001] The invention relates to a formula and a configuration method of a culture material used for the cultivation of hairy fungus, and belongs to the technical field of edible fungus cultivation. Background technique [0002] Fungus is one of the edible fungi with increasing demand in the international market. It is known as "jellyfish skin on wood". It is not only rich in nutrition, but also has special [0003] The health function is more popular with the popular black food in the world. At present, people generally use straw, cottonseed husks, corn cobs, etc. as the main materials when cultivating fungus, and add some bran, edible fungus fertilizer, etc. The cost is high, and the source of materials is limited. At the same time, most areas are greening forest belts. , The fast-growing forest belt has a large number of branches and wood chips produced during the trimming and logging process, most of which are burned as firewood or naturally decayed, which not ...
