Abstract

The invention relates to a method for producing selenium-rich and zinc-rich Pleurotus geesteranus and belongs to the technical field of agricultural production. According to the method, moderate sodium selenite and zinc sulfate are added to culture media and culture materials involved in the production process of the Pleurotus geesteranus, so that abilities of enriching selenium and zinc from a strain culture process to the production process are improved, Pleurotus geesteranus hyphae continuously absorb the selenium and the zinc in the culture media in the process of growth and convert the selenium and the zinc into bioorganic selenium and zinc, contents of the bioorganic selenium and zinc of Pleurotus eryngii products are increased, and the selenium-rich and zinc-rich Pleurotus geesteranus can be produced.

Description

1. Technical field [0001] The invention relates to a production method of selenium-enriched and zinc-enriched rare mushrooms, belonging to the technical field of agricultural production. 2. Background technology [0002] Xiuzhen mushroom is a new fungus imported from Taiwan. It has high nutritional value and is in short supply in the market. Its production has developed from the seasonal development of greenhouses to the annual production of cold storage. Xiuzhen mushroom is not only rich in nutrition, but also delicious. Its protein content is higher than that of Agaricus bisporus, shiitake mushroom, and straw mushroom. According to the determination by the Sports Soil and Fertilizer Research Institute of the Academy of Agricultural Sciences, fresh mushrooms contain 3.65-3.88% protein, 1.13-1.18% crude fat, 0.87-1.80% reducing sugar, 23.94-34.87% sugar, 2.64% lignin, 12.85% cellulose, fruit Glue 0.14%, also contains cellulose, minerals, etc. The protein content of xiuzhen...
