NOVELTY - Cultivation of Hericium erinaceus involves taking 70-80 wt.% bagasse, 18-22 wt.% soybean meal, 3-4 wt.% mushroom, 0.2 wt.% potassium dihydrogen phosphate and 1.3 wt.% gypsum where bagasse and mushrooms are dried and crushed into granules, adding mushroom with water, soaking, mixing with bagasse and soybean meal, piling, inserting stick, covering with grass for fermentation, turning when the material temperature reaches 60 degrees C for 24 hours, turning once a day, adding gypsum for the first turning and potassium dihydrogen phosphate for second turning, cooling and harvesting.    USE - Method for cultivating Hericium erinaceus (claimed).    ADVANTAGE - The method is environment-friendly and labor-saving and has high conversion rate.    DETAILED DESCRIPTION - Cultivation of Hericium erinaceus comprises:(1) taking 70-80 wt.% bagasse, 18-22 wt.% soybean meal, 3-4 wt.% mushroom, 0.2 wt.% potassium dihydrogen phosphate and 1.3 wt.% gypsum where bagasse and mushrooms are dried and crushed into granules;(2) adding mushroom with 20-30 times the weight of water, soaking at room temperature for 18-24 hours, mixing with bagasse and soybean meal, piling into 1.0-1.2 m high and 2-3 m wide where each pile of culture material dry weight is controlled to 300-500 kg, inserting stick with diameter of 10-15 cm where stomatal density is 1/m3 and covering with grass for fermentation;(3) turning when the material temperature reaches 60 degrees C for 24 hours, turning once a day, adding gypsum for the first turning and potassium dihydrogen phosphate for second turning where turning is done for 3-4 times (5-6 days) and terminating fermentation where moisture content of planting material is 63-65%;(4) cooling, laying directly into the furrow and covering with 2-2.5 cm thick loam; and(5) harvesting depending on mycelial growth and spraying with 0.01-0.02 g/ml mushroom leaching solution at an amount of 4-6 kg/m2. The mushroom leaching solution is prepared by adding mushroom with 20 times the weight of water, soaking at room temperature for 18-24 hours, filtering and diluting water to original amount to obtain 0.05 g/ml mushroom leaching solution.
