Organic selenium-rich pleurotus eryngii cultivation method

Abstract

The invention provides a method for cultivating Pleurotus eryngii rich in organic selenium. The method for cultivating Pleurotus eryngii rich in organic selenium comprises: step 1, screening the first-grade strains; step 2, screening the second-grade strains; step 3, screening the third-grade strains; and step 4, screening the selected strains The above-mentioned three-level strains were inoculated into the compost of Pleurotus eryngii for cultivation. The method for cultivating Pleurotus eryngii rich in organic selenium provided by the present invention has put an end to the situation of spraying inorganic selenium on the artificial foliage in the past and externally forcibly increasing the content of selenium element; High utilization rate and conversion rate, strong selenium tolerance and stability; high quality and high yield of cultivated products.

Description

technical field [0001] The invention relates to the technical field of edible fungus cultivation, in particular to a method for cultivating Pleurotus eryngii rich in organic selenium. Background technique [0002] Selenium is one of the essential trace elements for the human body. It enjoys the reputation of "longevity element", "king of anti-cancer" and "natural detoxifier". Glycerin peroxidase protects the cell membrane from oxidative damage and maintains its permeability; secondly, selenium-P protein has the function of chelating heavy metals and other poisons and reducing the toxicity of poisons. Studies have shown that compared with inorganic selenium, organic selenium has the advantages of less toxicity, easy absorption by animals, and less environmental pollution, and has higher practical value. Among them, using edible fungi as a carrier to convert inorganic selenium into organic selenium is one of the research hotspots in the field of fungal health food. [0003] ...

Problems solved by technology

[0007] In order to solve the advantages of the cultivation method of Pleurotus eryngii rich in organic selenium, the Selenium tolerance and stability of Pleurotus eryngii strains are not strong, the composition of the culture medium is unscientific, the cost of the culture medium is high, the cultivation process is complicated, and the quality and yield of the cultivation products are not good. High problem, the present invention provides a kind of cultivation method that is rich in organic selenium Pleurotus eryngii, it has culture medium composition suitable for the growth of Pleurotus eryngii, strong stability of dominant Pleurotus eryngii bacterial strain, simple cultivation method and cultivated Pleurotus eryngii The advantages of high mushroom quality and high yield
