A kind of culture material for cultivating white fungus and preparation method thereof

Abstract

The invention provides a culture medium for culturing tremella. The culture medium is prepared from 40-60% of cotton seed hulls, 20-40% of straw biogas residues, 15-20% of bran, 3-5% of corn flour, 1-2% of land plaster and 1-2% of saccharose. According to the growth features of tremella, the best ingredients are screened out through a large number of experiments; by adding the straw biogas residues, lignocellulose organic matter, nitrogen, phosphorus, potassium and various microelements can be sufficiently utilized for tremella, waste resources can be sufficiently utilized to be converted into tremella sporocarp with high economic value, agroecological environment can be protected, and development of agroecological environment is promoted. By the adoption of the culture medium for culturing tremella, rapid spawn running of tremella can be promoted, tremella emergence time can be shortened by 2-3 days, culture management cost can be reduced, and the culture facility utilization rate is improved; in addition, the culture medium is lower in cost, better in economic benefit and easy to apply and popularize.

Description

technical field [0001] The invention relates to a culture material for cultivating white fungus and a preparation method thereof. Background technique [0002] Tremella, also known as white fungus, snow fungus, etc., belongs to the fungus Tremellaceae Tremella, it is rich in nutrients, has the effect of invigorating the spleen and appetizing, and has the functions of benefiting qi and clearing the intestines, nourishing yin and moistening the lungs, and moisturizing the skin. It has been used since ancient times. Known as "the crown of fungi", it is the "life-prolonging product" and "immortality medicine" of royal nobles in all dynasties, and it is a nourishing yin tonic suitable for long-term consumption. [0003] During the growth of white fungus, there is an associated bacterium called ash fungus, which has many cellulase, hemicellulase and laccase, etc., which can decompose cellulose, hemicellulose and lignin well, and contribute to the growth and development of white fu...

Problems solved by technology

[0006] Tremella cultivation includes traditional basswood cultivation and compost cultivation. The yield of basswood cultivation is low, the production cycle is long, and it cannot be intensively produced. At present, 95% of the tremella production in my country is cultivation of compost, and the compost is mainly cottonseed hulls and miscellaneous wood chips. Mainly, but the output of sawdust compost is not high, while the price of cottonseed hulls has risen sharply, the cost of tremella cultivation has increased, and the economic benefits are not high
