High-efficiency culture medium for improving nutrient content of pleurotus ostreatus and preparation method therefor

Abstract

The invention discloses a high-efficiency culture medium for improving nutrient content of pleurotus ostreatus. The high-efficiency medium comprises the following components in parts by weight: distillers grains, talcum powder, soy germ meal, ferrous citrate preparation, fermented bamboo sawdust, cedar sawdust, ferrous lactate, alginate, quasi-boehmite, lignin sulfonate, turmeric dregs, stevia, bran, soy protein powder, licorice dregs, motherwort slag, loofah sponge and saccharomycetes. The fermented licorice dregs and motherwort slag are added into the pleurotus ostreatus culture medium, so that the ingredient of the pleurotus ostreatus culture medium is improved. Meanwhile, in the fermentation production process of the pleurotus ostreatus culture medium, the loofah sponge loaded accharomycetes are adopted for fermentation; gradual warming fermentation is firstly performed to promote reproductive development of the accharomycetes in a loofah sponge nutrition carrier, so that the fermentation time is effectively shortened. Gradual cooling fermentation is then performed, so that formation of fermented products is effectively regulated, and rich available organics for pleurotus ostreatusare provided. The pleurotus ostreatus cultivated by the culture medium has the characteristics of being large in size, good in taste and rich in nutrients.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a high-efficiency medium for improving the nutritional content of oyster mushrooms and a preparation method thereof. Background technique [0002] Pleurotus ostreatus is flat in nature, sweet in taste, has the effects of tonic and anti-cancer, can improve human metabolism, enhance physical fitness, and regulate autonomic nerves. Pleurotus ostreatus contains polysaccharides, which have a strong inhibitory effect on tumor cells and have immune properties. Pleurotus ostreatus also has the functions of chasing wind and dispersing cold, relaxing tendons and activating collaterals, and can treat waist and leg pain, numbness of hands and feet, and meridian discomfort. In addition, Pleurotus ostreatus has curative effects on hepatitis, chronic gastritis, gastric and duodenal ulcers, ricket disease, high blood pressure, etc. It also has certain effects on lowering blood...

Problems solved by technology

In order to pursue the high-efficiency cultivation of Pleurotus ostreatus in the market, chemical fertilizers are often added. Although the size of the produced Pleurotus ostreatus increases and the output increases, the produced Pleurotus ostreatus has low nutritional content, poor quality, and poor taste.
