Embodiment 1
[0070] Embodiment 1 Pleurotus eryngii selenium-enriched cultivation embodiment
[0071] Preparation of selenium-enriched Pleurotus eryngii additive:
[0072] ①Screen, dry, and crush corn cobs, a kind of natural crop waste, to a particle size of 0.005-0.1mm, and design the formula of the cultivation material additive required for the cultivation of selenium-enriched Pleurotus eryngii.
[0073] The additive formula is as follows:
[0074] 100 parts of corncob powder;
[0075] Sodium selenite 0.0011~0.0022 parts.
[0076] ② Grind the above sodium selenite to a powder with a particle size of 0.005-0.1 mm, and fully stir and mix with corncobs to obtain a mixture with a particle size of less than 0.1 mm and a selenium content in the range of 5-10 mg / kg.
[0077] ③ Process and granulate the above mixture to make it into particles with different particle sizes, and the particle sizes are controlled within the ranges of 0.005-0.1mm, 0.1-1.0mm, and 1.0-5.0mm respectively.
