From waste to wealth: effects of nine agroforestry wastes on Stropharia’s traits & yield

To broaden Stropharia rugosoannulata cultivation substrates, nine agricultural/forestry wastes were tested, evaluating fruiting body count, weight, and total yield, with factors influencing yield also investigated. Fig branches performed best: 16.5 % grade A fruiting bodies, 5.11 kg/m 2 total yield, and 232,000 yuan/hm 2 net profit. Grape stumps, pear and peach branches were also suitable, with yields 5.38, 4.64, 4.62 kg/m 2 respectively. Waste sawdust had 16.2 % grade A but limited economic benefits. Willow branches (9.5 % grade A), crape myrtle branches (8.4 %), soybean stalks (12.5 %), and corn stalks (4.04 kg/m 2 total yield) were suboptimal, needing reduced use. Correlation analysis showed first harvest reflects suitability; high lignocellulose materials enhance individual mushroom quality.
