Method for preparing culture strains of Agaricus bisporus (Lange) Sing by fermenting culture materials

Abstract

The invention discloses a method for preparing culture strains of Agaricus bisporus (Lange) Sing by fermenting culture materials and belongs to the technical field of culture of edible mushrooms. According to the method, 1,500kg of dried wheat straw (or rice straw), 1,500kg of dried cow dung, 25kg of urea, 50kg of lime powder, 30kg of calcium superphosphate, 50kg of gypsum powder and 40kg of calcium carbonate are used in the formula of the culture materials for culture strains of Agaricus bisporus (Lange) Sing. The culture materials are treated with outdoor fermentation and indoor post-fermentation technologies, a plastic basket which is 50cm long, 30 cm wide and 30 cm high is used as a container, and the culture strains of Agaricus bisporus (Lange) Sing are prepared through inoculation and cultivation. Compared with a currently commonly used method for preparing the culture strains from wheat serving as a main culture medium, the method has the advantages of grain saving, labor saving, energy saving, cost saving, shortening of strain preparation time, consistent culture age, short spawn running time after sowing and low probability of pollution of mixed fungi. The wheat straw (or rice straw) can be sufficiently utilized, environmental pollution caused by straw burning is reduced, and ecological balance is maintained.

Description

technical field [0001] The invention belongs to the technical field of edible fungus cultivation, and in particular relates to the production of Agaricus bisporus cultivars. Background technique [0002] Agaricus bisporus[ Agaricus bisporus (Lange) Sing], also known as mushrooms, white mushrooms, sea mushrooms, bisporus, etc., belong to Basidiomycotina, Laminomycetes, Agaricaceae, Agaricaceae, and the genus Agaricus. They are distributed in 72 countries in the world, mainly in Europe, Eastern Asia, North America, and Australia are the main producing areas. my country's Fujian, Anhui, Henan, Shandong, Guangdong, Zhejiang, Jiangsu, Taiwan and other provinces and cities all have production, with Fujian producing the most. At present, the national cultivation area of ​​Agaricus bisporus is 100 million m 2 about. [0003] Agaricus bisporus is white in color, pink in gills, delicious in color, crisp and tender in texture, and rich in nutrition. Every 100g of dried mushrooms c...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: ① use wheat as the main raw material to produce cultivars, and every 1m of cultivation 2 Agaricus bisporus needs about 0.2Kg of wheat, according to the national cultivation area of ​​Agaricus bisporus is 100 million m 2 Calculate, need wheat 20 million Kg, consume a large amount of food

② High-pressure steam sterilization consumes a lot of energy

It has brought great difficulties to the production of cultivated species
