Auricularia auricula culture medium and preparation method thereof

Abstract

The invention particularly relates to an auricularia auricula culture medium and a preparation method thereof. The culture medium comprises, by weight, 20-50 parts of mulberry twigs and leaves, 20-40 parts of gingko branches and leaves, 10-25 parts of lentinula edodes waste, 5-15 parts of tartary buckwheat, 5-15 parts of enteromorpha, 3-10 parts of sweet potatoes, 1-3 parts of lime powder, 0.15-0.35 part of radix astragali, 0.5-1 part of herba houttuyniae, 0.5-1.5 parts of usnea, 0.3-1 part of fructus perillae and 0.5-1.5 parts of radix sophorae flavescentis. Water accounts for 50-70% of the total weight of the culture medium. The preparation method of the auricularia auricula culture medium mainly includes the steps of main material alkali treatment, traditional Chinese medicine component extraction, auxiliary material preparation and culture medium preparation. Auricularia auricula cultured through the culture medium and the method is high in yield, diversified in nutrient and high in microelement and inorganic element content.

Description

technical field [0001] The invention belongs to the research field of black fungus cultivation, and in particular relates to a black fungus culture medium and a preparation method thereof. Background technique [0002] Black fungus has been a famous edible fungus and medicinal fungus in my country since ancient times. It is not only delicious, but also rich in protein, carbohydrates, vitamins, minerals and other nutrients. Efficacy is widely cultivated in our country. In recent years, with the rapid development of black fungus cultivation, the consumption of forest resources is increasing day by day. In order to meet the market supply of black fungus and protect the ecological health of the forest, more and more people began to pay attention to the development of alternative materials for black fungus cultivation. The cultivation and production of black fungus as a substitute material has a short cycle (generally it only takes about 120 days to complete a production cycle),...

Problems solved by technology

In addition, the current compost formulations are various, some of which are too rich in nutrients, resulting in high cost but slow growth of mycelium and low yield. Nutritional imbalance causes low survival rate of strains, easy aging of mycelium, causing strain variation, affecting the growth of fungus in the later stage, and even Cause serious consequences such as reduction in production and quality of fungus, and the ingredients of most black fungus culture medium are unscientific and unreasonable in nutritional structure, easy to be infected by miscellaneous bacteria, do not have antibacterial and antibacterial functions, and are easy to produce black fungus. The rate of the first-grade fungus cultivated is low, resulting in low economic benefits for growers
