摘要： Because of the regular annual harvest, Phragmites australis used in wetland protection produces an abundance of straw, resulting in a large amount of straw waste. As a result, the extra straw should be used in a convenient and efficient manner. A comprehensive analysis of P. australis straw use in Pleurotus cultivation and spent mushroom substrate compost was performed in this study to increase its value. The lignocellulose content in the straw was shown to meet the nutritional requirements of the Pleurotus mushroom. Immediately thereafter, the replacement of bagasse with P. australis proved to be reasonable for Pleurotus eryngii substrate and could generate a profit of yen 17,400 per 10,000 cultivation bags. Substituting P. australis for approximately 20 % to 40 % of bagasse is recommended for Pleurotus ostreatus cultivation and can yield a profit of approximately yen 16,000. Spent mushroom substrate compost was confirmed to increase the organic matter content, and post-compost use of this substrate as a fertilizer could increase economic income by approximately yen 1000 for every 10,000 bags. Overall, this recycling pathway for P. australis resources presents positive ecological and social benefits, and the model is a sustainable and eco-friendly solution for agricultural waste worthy of promotion and further application.
