NOVELTY - Cultivating Stropharia rugosoannulata comprises: adding clean water into mushroom stem particles and soaking at room temperature, adding the mushroom stem along with soaking liquid into straw for pre-wetting, then piling to ferment, sowing Stropharia rugosoannulata; harvesting the mushroom, spraying mushroom stem leachate, spraying 5-8 kg/m2 to rejuvenate mycelium, where the mushroom stem leachate is prepared by soaking the mushroom stem in 20 times amount of water for 18-24 hours, filtering the residue, making up to its original volume to obtain 0.05 g/ml dilution.    USE - The method is useful for cultivating Stropharia rugosoannulata (claimed).    ADVANTAGE - The method is environmentally-friendly, economical and saves labor.    DETAILED DESCRIPTION - Cultivating Stropharia rugosoannulata comprises: (a) taking 72-78% straw, 14-18% mushroom residue, 4-5% mushroom stem, 3.5% lime and 1% light calcium carbonate as dry raw materials, where the straw comprises rice straw, wheat straw, corn straw, rapeseed straw and/or cassava straw which are dried and crushed into 2-3 cm pieces, the mushroom residue is remaining scraps of Pleurotus eryngii which is dried and crushed, and the mushroom stem is a stem of shiitake mushroom which is dried and crushed into 2-3 mm pieces; (b) adding 20-30 times clean water into mushroom stem particles and soaking at room temperature for 18-24 hours, adding the mushroom stem along with soaking liquid into straw for pre-wetting, then piling to a height of 1.2-1.5 m and a width of 2-3 m, controlling dry weight to 300-500 kg, tapping for 4 weeks, providing vent of 10-15 cm using a stick with a pore density of 1/m3, allowing it to ferment for 8-10 days by turning once for every two days, totally turning for 3-4 times, adding water depending on moisture content, terminating the fermentation, providing a moisture content of 63-65% to obtain fermented planting material, cooling, sowing Stropharia rugosoannulata, then harvesting after the mycelium covers 2/3rd part with a thickness of 3-4 cm; and (c) harvesting the mushroom, spraying 0.01-0.02 g/ml mushroom stem leachate, spraying 5-8 kg/m2 to rejuvenate mycelium, where the mushroom stem leachate is prepared by soaking the mushroom stem in 20 times amount of water for 18-24 hours, filtering the residue, making up to its original volume to obtain 0.05 g/ml dilution.
