NOVELTY - Method for preparing mushroom rich in trace elements, involves (a) preparing mushroom feed medium by adding 5-10 wt.% ceramic and/or functional ceramic particles and preparing culture medium, and (b) spraying selenium, germanium, zinc and chrome vanadium mineral ion nutrient liquid fertilizer, spray-drying fertilizer, harvesting the mushroom for 10 days, diluting 300-500 times liquid to the harvested mushroom, moisturizing mushroom, spraying 2-3 times liquid on the mushroom, drying the mushroom, transplanting the mushroom culture, and harvesting the mushroom.    USE - The method is useful for preparing mushroom rich in trace elements (claimed).    DETAILED DESCRIPTION - Method for preparing mushroom rich in trace elements, involves (a) preparing mushroom feed medium by adding 5-10 wt.% ceramic and/or functional ceramic particles, preparing culture medium for the above-mentioned feed, granulating the mixture to obtain ceramic granule, where the ceramic health material is of ZL200610014778.3 and the ceramic granule is of ZL200610014778.3, where the granule has spherical diameter of 1-2%, sintering the granule at 900-1100 degrees C, adding nutritious egg with enhanced microelement liquid, diluting the liquid using 200-500 times clear water, uniformly mixing special flavor of culture medium, bagging the culture medium, sterilizing the mushroom culture bag, punching the mushroom strain in mushroom culture bag and managing the culture, and (b) spraying selenium, germanium, zinc and chrome vanadium mineral ion nutrient liquid fertilizer, spray-drying fertilizer, harvesting the mushroom for 10 days, diluting 300-500 times liquid to the harvested mushroom, moisturizing mushroom, spraying 2-3 times liquid on the mushroom for 5-7 days, crushing and drying the mushroom, diluting the 100-300 times clear water on the dried mushroom, soaking the dried mushroom in 100-300 times nutrient solution for 48 hours, fully absorbing the nutrient solution, bagging and sterilizing the nutrient solution, culturing the mushroom culture, transplanting the mushroom culture, growing and managing mushroom transplant, harvesting the large mushroom bud for 10 days, diluting the nutrient solution for 300-500 times clear water, spraying nutrient solution for 1-2 times mushroom for 7-10 days, spraying the 300-500 times diluted fertilizer for 2-3 times at an interval of 5-7 days, and repeatedly performing the above-mentioned mushroom.
