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

Embodiment 1

[0034] A preparation method for a culture material for cultivating white fungus, comprising the following steps:

[0035] (1) Raw material preparation

[0036] Naturally dry the biogas residues until the water content is below 15-17%, moderately crush them, sieve them through a 4-mesh sieve, expose the cottonseed hulls to the sun, remove impurities respectively, and weigh 40kg of cottonseed hulls, straw biogas residues 40kg, bran 15kg, corn flour 3kg, gypsum powder 1kg and sucrose 1kg, spare;

[0037] Pour the cottonseed husks on the stockyard to build a heap, water to make the water fully infiltrate, then evenly spread the straw residue, bran, and corn flour from the top of the heap, and evenly sprinkle the gypsum powder on the material surface, and finally Thoroughly stir the above raw materials, then dissolve the sucrose in water, the weight of water is about 1.1 times of the weight of the raw materials, mix the materials and water evenly, pile up for about 1 hour.

Embodiment 2

[0047] A preparation method for a culture material for cultivating white fungus, comprising the following steps:

[0048] (1) Raw material preparation

[0049] The biogas residue is naturally sun-dried until the moisture content is below 15-17%. Moderately pulverize, sieve with a 4-mesh sieve, expose the cottonseed hulls to the sun, remove impurities respectively, weigh 60kg cottonseed hulls, 20kg straw biogas residues, 15kg bran, 3kg corn flour, 1kg gypsum powder and sucrose according to the culture material formula and cultivation amount 1kg, spare;

[0050] Pour the cottonseed husks on the stockyard to build a heap, water to make the water fully infiltrate, then evenly spread the straw residue, bran, and corn flour from the top of the heap, and evenly sprinkle the gypsum powder on the material surface, and finally Thoroughly stir the above raw materials, then dissolve the sucrose in water, the weight of water is about 1.1 times of the weight of the raw materials, mix the ...

Embodiment 3

[0060] Cultivation test: Tremella cultivation experiment was carried out with the Tremella compost prepared in Example 1 and Example 2 and the same amount of compost without adding straw biogas residues. The earing time of white fungus is 15 days, which is 2 to 3 days earlier than that of the same amount of culture material without adding straw biogas residue under the same cultivation environment, and the yield of white fungus is the same as that of the same amount of culture material without adding straw biogas residue. Tremella is equal, but the cost of raw materials is saved by about 10-20%, and it has a good cultivation effect.

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...
