Problems solved by technology

The compost after harvesting of Pleurotus eryngii still contains many ingredients that are beneficial to the production of mushrooms. It is discarded as waste, or the raw material of organic fertilizer. The beneficial components in the compost have not been fully utilized, and the production of Pleurotus eryngii has increased accordingly. cost, on the other hand, the discarding of the waste after the factory cultivation of Pleurotus eryngii will also pollute the environment

Abstract

The invention discloses a pleurotus eryngii culture medium and an industrial culture method. The pleurotus eryngii culture medium comprises 20-40% of corn cob, 20-40% of bagasse, 5-15% of bran coat, 5-15% of corn flour and 10-30% of wood dust. The pleurotus eryngii culture method comprises the following steps: proportioning, bagging, sterilizing, discharging, cooling, inoculating, growing the bacterium, afterripening, scratching the bacterium, growing sporophores, collecting and the like. Compared with the prior art, the method has the advantage of abundant and accessible raw materials and greatly lowers the cost of the culture medium. Compared with the traditional formula, the culture medium disclosed by the invention has the following advantages: the hypha bagfull time is shortened by 1-4 days, the growth cycle is shortened by 3-6 days, and the yield per unit volume is enhanced by more than 60% as compared with the conventional one-stubble culture.

Description

technical field [0001] The invention relates to an edible fungus culture substrate and a cultivation method, in particular to a pleurotus eryngii culture substrate and a factory cultivation method. Background technique [0002] Pleurotus eryngii (Pleurotus eryngii) belongs to the fungal phylum Basidiomycetes Agaricaceae, Pleurotaceae, Pleurotus genus, also known as Pleurotus eryngii. Pleurotus eryngii is a rare edible fungus species that integrates food and medicine. The mushroom meat is thick, crisp and tender, fragrant and nutritious. It has a pleasant almond fragrance and abalone-like taste. It is suitable for fresh-keeping and processing, and is deeply loved by people. Since the introduction and cultivation of Pleurotus eryngii in my country in the late 1990s, the domestic industrial production of Pleurotus eryngii has developed rapidly, and the in-depth research on the industrial cultivation of Pleurotus eryngii has also gradually increased and improved. And cultivati...
