[0069] Example 1 Selenium-enriched Cultivation Example of Pleurotus chinensis
[0070] (1) Preparation of selenium-enriched mushroom additive:
[0071] ①Screen, dry and crush corncobs, a kind of natural crop leftovers, to a particle size of 0.005-0.1mm, and design the formula of cultivation material additives required for cultivating selenium-enriched pear mushrooms.
[0072] The additive formula is as follows:
[0073] 100 parts of corncob powder;
[0074] Selenium yeast 0.45~0.9 parts.
[0075] ②The above-mentioned selenium yeast is Zhejiang Shenyou selenium yeast, the average particle size is 0.1mm, and the total selenium content is 2000mg / kg; after it is crushed to a particle size of 0.005-0.1mm, it is fully stirred and mixed with corncob powder to prepare The particle size is less than 0.1 mm, and the selenium content is in the range of 5-10 mg / kg.
[0076] ③ Process and granulate the above mixture to make it into particles with different particle sizes, and the parti...
