The invention discloses a method for planting and cultivating Stropharia stropharia, which comprises the following steps: (1) After sterilizing the medicinal dregs with high-pressure steam, inoculating the bacillus licheniformis bacterial liquid according to the inoculum amount of 8-12%, and then fermenting at a constant temperature After cultivating for 5-7 days, after high-pressure steam sterilization, the medicinal dregs fertilizer is obtained; (2) the yellow storage corn stalks and corncobs are added to the pulverizer for crushing, and the medicinal dregs fertilizer with a total mass of 8-10% is added thereto , after mixing and stirring evenly, the culture substrate is prepared; (3) using furrow cultivation, after the first layer of material is 10-12cm, sow the Stropharia stropharia strain, cover the mixed soil, water thoroughly, cover the film, and wait until After the mycelia cover the soil layer, the film is removed, and when the surface temperature exceeds 25°C, the water is sprayed. The method for planting and cultivating Stropharia stropharia provided by the present invention has the advantages of simple operation, low cost, and environmental protection, and can effectively improve the output and quality of Stropharia stropharia.

The invention relates to a preparation method of composite microbial inoculum for producing silage from rotten vegetable leaves and straw. The method comprises the following steps of (1) uniformly mixing milk with brown sugar in proportion so as to obtain a solution A; (2) adding lactic acid bacteria mixed liquor to the solution A, performing uniform mixing to obtain mixed liquor, and adding inorganic salts to the mixed liquor in a manner of adding 1 part of the inorganic salts to each liter of the mixed liquor so as to obtain a solution B; (3) adding corn flour to the solution B, and performing uniform stirring so as to obtain raw materials of which the moisture content is 30-45%; and (4) loading the raw materials into anaerobic bags, performing fermentation under the condition of 28-36 DEG C for 3-5 days, when the pH value reaches 3.8-4.1 and lactic acid bacteria reach 2-20 billion cfu / g, performing drying under an aseptic condition, performing crushing, and performing bagging so as to obtain the microbial inoculum special for the silage. The preparation method disclosed by the invention is simple in technology and low in cost; and through the obtained composite microbial inoculum, the fermentation time of the silage is shortened, and the fermentation efficiency is improved.

The invention provides a sulfur-dioxide-free full juice fermented orange wine and a production process thereof, belonging to fermented fruit wines and production technologies thereof. The production process comprises the steps of making the juice turbid and making the pulp resist oxidation, adjusting the acidity of the juice and neutralizing bitter precursor substances, making the juice resist bacteria and adjusting the sugar content, preparing mother liquor of the wine, blending and fermenting the juice, ageing the wine base, fining and blending the aged wine base and adjusting the taste of the aged wine base, wherein the juice comprises essential oil, calcium oil and bitter substances. The orange wine has the beneficial effects that an innovative process of replacing SO2 with a composite of non-toxic materials such as antibacterial and oxidation-resistant D-erythorbic acid, nisin, sorbic acid, chitosan and the like is adopted; compared with traditional processes, in the production process, the operation of adding toxic gaseous and liquid SO2 step by step is safer and more convenient; the production process is an innovation of popularizing the traditional processes of wines for more than a hundred years to make wine with other fruit raw materials; the navel orange wine produced by the technology does not contain SO2 and has the advantages that the content of methanol is reduced by about 90%, the content of fusel oil is reduced by about 65% and the harmful ingredients such as bioamine, sulfate, methanol, fusel oil and the like are controlled compared with the fruit wines produced by the traditional processes.

The invention discloses a method for making feed for ruminants by using edible mushroom residues as raw materials. The invention grinds edible fungus slag, adds additives composed of sodium diacetate, laccase, lactic acid bacteria and other raw materials, and the product after closed fermentation is used as ruminant feed. The invention realizes the method of preparing ruminant feed with edible mushroom residue as a single raw material, and has low cost and simple process. The fermentation product is easy to preserve, the loss of nutrients is small, and the components such as cellulose and anti-nutrients are effectively degraded. The invention can obviously improve the resource utilization level of the edible mushroom waste residue.
