Embodiment 1
[0051] Preparation of inorganic selenium source: 560g (5mol) of selenium dioxide and 280g (5mol) of potassium hydroxide were reacted in 20L of water, and 2040g of potassium dihydrogen phosphate (15mol) was added for dissolution to prepare a selenium source aqueous solution containing 20mg / ml of selenium.
[0052] Preparation of selenium-enriched base material:
[0053] The proportioning (by weight percentage) of sawdust base material: sawdust 85%, bran 13%, brown sugar 1%, calcium sulfate powder 1%.
[0054] The calculated amount of inorganic selenium source is dissolved in water, sprayed on the calculated amount of sawdust base material, and mixed uniformly to prepare the selenium-enriched base material.
[0055] Preparation of selenium-enriched Ganoderma lucidum medium: 1.5kg of selenium-rich base material and 8.5kg of wood segments were packed in each bag, sterilized, and the selenium content in the medium was 30mg / kg.
[0056] Cultivation: The cultivars of Ganoderma lucid...
