Abstract

The invention method provides a cultivation method of high-selenium coprinus comatus. The cultivation method is achieved by configuring cultivation matrix composed of a basic cultivation material and selenium-rich cultivation material additive. The selenium-rich cultivation material additive occupies 1-10% of the total weight of a cultivation dry material, selenium amount of the selenium-rich cultivation material is 10-500mg/kg, particle size of particles in the selenium-rich cultivation material additive is in the range of 0.05-5.0mm, and the particles are in multi-particle-size areal distribution. The selenium-rich cultivation material additive comprises by weight, 100 parts of corncob powder or straw powder of other crops and 0.5-20 parts of organic selenium yeast. The coprinus comatus cultivated by the method has strong utilization ability of selenium, fruiting body selenium content is high, enrichment factor of a fruiting body to the selenium is high, the proportion of organic selenium in the fruiting body of the coprinus comatus accounting for the total selenium reaches up to above 90%, and the selenium shape is safe. The cultivation method of the high-selenium coprinus comatus is simple to operate and strong in practicability.

Description

technical field [0001] The invention relates to edible fungi, in particular to a method for cultivating high-selenium Coprinus comatus, and belongs to the technical field of biotransformation of selenium resources. Background technique [0002] Selenium is an essential trace element for the human body. It is an essential component of glutathione peroxidase in the body. Selenium has an antioxidant effect and is closely related to human health. Selenium has anti-cancer, heart protection, anti-hepatic necrosis, and prevention of myopia and cataracts , detoxification, improve immunity, delay aging and enhance reproductive function and other pharmacological effects. According to incomplete statistics, there are more than 40 countries and regions lacking selenium in the world, and 72% of the regions in my country are selenium-deficient regions. Therefore, it is being sought and developed for selenium-enriched products to ensure that the human body absorbs sufficient selenium. Scie...
