Abstract

The invention discloses a method for culturing pleurotus geesteranus uniformly rich in selenium by using selenium-enriched crop stalks. The method is characterized by comprising the steps of: mixing selenium-enriched culture material additive in an amount which is 1 to 10 percent of the total weight of a dry culture material in the dry culture material, and culturing according to the common culture method to obtain the pleurotus geesteranus uniformly rich in selenium, wherein the selenium-enriched culture material additive has the total selenium content of 5 to 50mg / kg; the particles with theparticle size of 0.005 to 5.0mm in the selenium-enriched culture material additive are in multi-particle-size regional distribution, and particles with the particle size of 1.0 to 5.0mm at least account for 10 percent of the total weight of the additive; particles with the particle size of 0.005 to 0.1mm at least account for 40 percent of the total weight of the additive; and the selenium-enriched culture material additive comprises the following components in percentage by weight: 30 to 70 percent of selenium-enriched wheat stalk powder and 30 to 70 percent of selenium-enriched cornstalk powder. The pleurotus geesteranus prepared by the method has high utilization rate and stable selenium content in different batches; in addition, by the method, selenium pollution is avoided, and the method is easy to operate and easy to promote.

Description

Technical field [0001] The invention relates to a method for fortifying selenium nutrition of edible fungi, in particular to a method for enhancing selenium nutrition of Xiuzhen mushroom by using high-selenium straws, and belongs to the technical field of biological transformation of selenium resources. Background technique [0002] Pleurotus geesteranus belongs to the genus Fungi, Basidiomycetes, Agaricus, and Pleurotus in taxonomy. Xiuzhen mushroom has a crisp texture, sweet and refreshing taste, delicious taste and rich nutrition. It has high edible and medicinal value and is an excellent strain in Pleurotus ostreatus. It is a high-protein, low-fat nutritious food, its protein content is close to meat, 3-6 times higher than ordinary vegetables, and its texture is delicate, less fiber content; more valuable is that it contains the race itself It cannot be manufactured, but threonine, lysine, homoamic acid, etc. which are usually lacking in food. This kind of edible fungus has...
