Agaricus subrufescens stock seed culture material and production method thereof

Abstract

The invention relates to the field of Agaricus subrufescens, and in particular relates to an Agaricus subrufescens stock seed culture material. The culture material comprises the following components in parts by weight: 6%-8% of yeast powder, 5%-8% of ammonium nitrate, 80%-85% of periostracum cicada, 1%-4% of glucose, 1%-3% of lime, and 1%-3% of gypsum. The invention relates to a production method of the Agaricus subrufescens stock seed culture material and the production method comprises the following steps: (1) raw material treatment; (2) stirring; (3) fermentation; and (4) sterilizing. According to the invention, the periostracum cicada is used for replacing cow dung, so as to provide rich nutrition and be beneficial to reducing the cadmium content of the Agaricus subrufescens.

Description

Technical field [0001] The invention relates to the field of Agaricus blazei, in particular to an Agaricus blazei original seed culture material and a preparation method. Background technique [0002] Agaricus blazei (also known as Brazilian mushroom) is delicious and has an almond flavor. Its mycelium and fruit bodies are rich in polysaccharides and protein. It has higher nutritional value and medicinal value than most other mushrooms, and improves human immunity. The function has a good effect, but also has the effect of inhibiting tumor cells. Regular consumption of Agaricus blazei Murrill has the effects of lowering blood lipids and cholesterol. At present, the cultivation of Agaricus blazei Murrill has been vigorously promoted in many areas. [0003] The cultivation materials for the production of Agaricus blazei Murrill are mostly traditional mushroom cultivation materials, that is, cow dung and rice straw are used for cultivation, and urea is used as the nitrogen source.

Problems solved by technology

But for a long time, there are still many difficulties in the production and cultivation of Agaricus blazei, which are manifested in: because Agaricus blazei naturally has a strong enrichment effect on cadmium, it is often detected that the content of heavy metal cadmium in the product exceeds the standard. After research, it is found that the reason One is that the cadmium in Agaricus blazei mainly comes from cow dung and the soil used as covering materials, among which cow dung is the most, and a small amount comes from straw and other auxiliary materials (such as lime, gypsum, bran, etc.), because most of the culture materials contain cow dung. The mixture of manure and soil creates conditions for Agaricus blazei to accumulate cadmium (Agaricus blazei mycelia and fruiting bodies have the characteristics of cadmium enrichment)
