Effect of Selenium Concentration in Cultivated Material on Yield,Quality and Product Safety of Pleurotus pulmonarius
The effects of total selenium concentration of cultivated material on yield,selenium content,nutrient composition and heavy metal content of fruit body were studied with 4 strains of Pleurotus pulmonarius as experimental materials.The results showed that the total selenium concentration of cultivated materials directly affected the selenium content in fruit body of P.pulmonarius,and the selenium content in fruit body increased with the increase of total selenium concentration.When the total selenium concentration was 0.07-1.47 mg·kg-1,the selenium content in the fruit body was within the specified range of Seleni-um-rich agricultural products(GH/T 1135-2017),the selenium was not exceeded,and the product was safe.When the total sele-nium concentration was 0.22 mg·kg-1,the biological efficiency rate of the tested strains was higher.With the increas of total se-lenium concentration,the crude protein content of P.pulmonarius fruit body could be increased.The content of arsenic,cadmi-um and lead in fruit bodies did not increase with the increase of total selenium concentration,and there was no synergistic effect between enriched selenium and arsenic,cadmium and lead.
