Abstract:

Taking Pleurotus eryngii cultivated on wood as the control, the mushroom cultivated on Phragmites australis substrate was analyzed for morphology, organic nutrients, and the contents of mineral elements and heavy metals. The feasibility of using Phragmites australis to cultivate mushroom instead of wood was proposed from morphology and nutrition perspectives. The results showed that there was no significant difference in the morphology, fresh weight and water content of Pleurotus eryngii between the two kinds of cultivation, as well as in the contents of crude protein, crude fat and amino acid. The contents of crude polysaccharide and zinc were significantly lower in mushroom cultivated on Phragmites australis than those on wood, but the calcium and iron contents were significantly higher in the former than in the latter. Although there were some differences of arsenic and cadmium contents of mushroom between Phragmites australis and wood cultivation, the mushroom cultivated on both substrates could meet the food safety standards. In general, Phragmites australis cultivating mushroom instead of wood has a huge potential for promotion.

Key words: Phragmites australis, edible mushroom, fresh weight, organic nutrients, trace elements, heavy metals
