Establishment method for brown mushroom three-level strain propagation system

Abstract

The invention discloses an establishment method for a brown mushroom three-level strain propagation system. The establishment method for the brown mushroom three-level strain propagation system comprises three-level strain propagation of stock cultures, liquid strains and cultispecies, wherein the formula of culture mediums of the stock cultures comprises, by weight (g / L), 600g of turfy soil, 20g of glucose, 100g of wheat grains, 1.5g of magnesium sulfate, 1g of monopotassium phosphate, 2g of peptone and 1000mL of water, the formula of the liquid strains comprises, by weight (g / L), 200g of potatoes, 20g of glucose, 2g of peptone, 2g of monopotassium phosphate, 1g of magnesium sulfate and 10.01g of VB, the pH (potential of hydrogen) is natural, and the cultispecies comprise, by weight (%), 92% of wheat grains, 5% of gypsum and 3% of turfy soil. Compared with a traditional solid state three-level strain, through using the propagation system, the propagation cycle is shortened by 38 days. The establishment method for the brown mushroom three-level strain propagation system is an optimum scheme, and has a certain guiding significance to the mass industrialized production of brown mushrooms.

Description

technical field [0001] The invention provides a cultivation method related to brown mushrooms, more specifically a method for multiplying brown mushroom tertiary strains. Background technique [0002] brown mushrooms ( Agaricus brunnescens Peck), is a rare species of mushrooms, belonging to Basidiomycotina (Basidiomycotina), Agaritales (Agaritales), mushroom family (Agaricaceae), mushroom genus ( Garicus ). Brown mushrooms, commonly known as brown mushrooms, are Bohemian subspecies. The strain has high yield, excellent mushroom quality, and fresh and tender taste. The mushroom cap is natural brown, the stipe is white, and the meat is dense and firm. All current white Agaricus species are white varieties of the brown mushroom, which means that the brown mushroom is the wild ancestor of the white Agaricus bisporus. Brown mushrooms, also known as white mushrooms and champignons, belong to Basidiomycetes, Agaricaceae, Agaricaceae, and Mushrooms. Brown mushrooms are rich in...

Problems solved by technology

[0004] Because the brown mushroom has a good market prospect, but there are few researches on its cultivation method at present, especially compared with the Agaricus bisporus tertiary bacterial strain breeding time is longer, the present invention aims at preparing the brown mushroom liquid bacterial strain and the production of cultivated species, and the best propagation plan for the third-level strains of brown mushrooms has been studied, which will have certain guiding significance for the large-scale industrial production of brown mushrooms
