Centralized secondary fermentation method for agaricus bisporus

Abstract

The invention discloses a centralized secondary fermentation method for agaricus bisporus. The culture medium comprises the following raw materials in parts by weight: 45-60 parts of forage, 35-50 parts of chicken manure, 2-8 parts of gypsum and 3-10 parts of oil cakes. The method comprises the following steps of: uniformly spreading forage in a pre-wetting pool for pre-wetting for 2-5 days; adding chicken manure, gypsum and oil cakes and uniformly and adequately mixing; filling the mixed fermentation material in a ventilating floor in a primary fermentation tunnel, and conveying fresh air to the fermentation material through a fan; fermenting for 4-6 days and transferring the fermentation material to another primary fermentation tunnel. The base material of the primary tunnel fermentation is uniformly stacked on the ventilating floor in a secondary fermentation tunnel, and the temperature of the fermentation material is controlled by operation of the fan. Secondary fermentation comprises the following steps: a balancing stage, a heating stage, pasteurization, cultivation at constant temperature and discharge at low temperature. According to the method, local wheat straw hoods, straws, chicken manure and the like are used as main raw materials to form the culture medium. Centralized scaled production cultivation materials are formed by the technology of pre-treatment of the raw materials, primary fermentation and secondary fermentation.

Description

Technical field [0001] The invention relates to edible fungi, in particular to a fermentation method of Agaricus bisporus. Background technique [0002] Agaricus bisporus is the world's most widely cultivated edible fungus with the largest output and consumption. It uses waste materials from planting and breeding as the production substrate, and the fruit body is rich in protein. At present, most domestic mushroom production is a simple cultivation method, with poor facilities, backward technology, small scale, low yield, poor quality, unreasonable formula and nutrient distribution ratio, irregular operation, and fermentation before the culture material (equivalent to a tunnel Fermentation) Affected by the external climate (temperature, rain, strong wind, etc.), fermentation is uneven, post-fermentation (equivalent to secondary tunnel fermentation) pasteurization and maintenance temperature is not in place, resulting in poor maturity of the culture material, bacteria and insects ...

AI Technical Summary

Problems solved by technology

At present, domestic mushroom production is mostly a simple cultivation method, with simple facilities, backward technology, small scale, low output, poor quality, unreasonable formula nutrient distribution, irregular operation, and pre-fermentation of compost (equivalent to a tunnel) Fermentation) Affected by the external climate (temperature, rain, strong wind, etc.), the fermentation is uneven, and the post-fermentation (equivalent to the second tunnel fermentation) pasteurization and temperature maintenance are not in place, resulting in poor maturity of the culture material, miscellaneous bacteria, insects, etc. Egg pollution is serious, which seriously affects the yield

Moreover, because farmers scattered and piled compost, it also had a certain impact on the rural environment.
