[0005] Pleurotus ostreatus is delicious, nutritious, easy to cultivate, high in yield, high in price and good in economic benefits. It is also rich in proteoglycans, which has a strong inhibitory effect on cancer cells and can enhance the immune function of the body. It is widely loved food However, Pleurotus ostreatus also has a strong selenium-enriching ability, which is a natural selenium carrier. It is a simple and effective method to produce selenium-enriched Pleurotus ostreatus with Pleurotus ostreatus. At present, the culture medium of Pleurotus ostreatus is mainly cultivated Inorganic selenium is added to the base, but due to the different cultivation regions, the temperature in each region is quite different, and the growth of Pleurotus ostreatus is fast, which will lead to the low utilization rate of selenium in the selenium-enriched cultivation process, thus failing to achieve better enrichment As a result, the fast growth of Pleurotus ostreatus will also lead to the unpleasant enrichment of nutrients such as protein and amino acids in Pleurotus ostreatus, resulting in the inability of the nutritional value of Pleurotus ostreatus to exert its maximum effect

Abstract

The invention relates to the technical field of cultivation of edible mushrooms, and particularly relates to a culture medium for promoting high yield of a selenium-rich oyster mushroom and a preparation method of the culture medium. The culture medium of the oyster mushroom is mainly improved, the culture medium is prepared from a substrate material, a nutrition additive, traditional Chinese medicine residues and a microelement solution at the weight ratio of (40-50):(7-11):(21-27):(2-5), the oyster mushroom reaches the optimal growth state by changing the composition of the substrate material and the formula, meanwhile, the selenium sulfite and the kieselguhr are also added and matched in use, so that the oyster mushroom is enriched with selenium; meanwhile, various wastes are also reasonably utilized, particularly, the organic matters and microorganisms in the wastes of a cassava alcohol residue, a needle mushroom waste and the traditional Chinese medicine residues are fully utilized, then the wastes are utilized in an energy-saving and environment-protecting way, the rich organic matters are also provided for the oyster mushroom, and the culture medium is an economical and scientific selenium-rich culture medium.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of edible fungus cultivation, in particular to a medium for promoting the high yield of selenium-enriched Pleurotus ostreatus and a preparation method thereof. [0003] 【Background technique】 [0004] Selenium is an essential trace element for the human body. Selenium deficiency in the human body can lead to Keshan disease, cancer, cataract, cardiovascular disease, diabetes, AIDS, etc. Supplementing selenium can eliminate free radicals in the body and reduce the viscosity of whole blood and plasma; due to the natural environment The content of selenium is very little, therefore, the research and development of selenium-enriched food has become the new direction of present agricultural development. [0005] Pleurotus ostreatus is delicious, nutritious, easy to cultivate, high in yield, high in price and good in economic benefits. It is also rich in proteoglycans, which has a strong inhibitory effect o...
