NOVELTY - Cultivating spring sowing shiitake mushrooms by utilizing biogas residues and biogas slurry comprises (i) processing raw material bagging stage by taking biogas residue as cultivation material, using biogas residue and biogas slurry containing mineral elements and organic nutrient in mushroom bag cultivation materials to promote mycelium robust growth, (ii) processing debagging, arranging and soil-covering stage, (iii) processing fruiting body differentiation-young mushrooms stages by spraying mixed nutrition liquid, and (iv) processing tide-changing intermittence stage.    USE - The method is useful for cultivating spring sowing shiitake mushrooms by utilizing biogas residues and biogas slurry (claimed).    ADVANTAGE - The method: fully utilizes biogas residues (slurry); reduces cost; and greatly improves the yield and the quality of the spring sowing shiitake mushrooms.    DETAILED DESCRIPTION - Cultivating spring sowing shiitake mushrooms by utilizing biogas residues and biogas slurry comprises (i) raw material bagging stage: taking biogas residue as cultivation material, using biogas residue and biogas slurry containing mineral elements and organic nutrient in mushroom bag cultivation materials to promote mycelium robust growth, uniformly mixing dry biogas residue, gypsum, calcium superphosphate and rice bran or wheat bran, mixing and stirring with wooden meal to obtain mixture, dissolving potassium dihydrogen phosphate, magnesium sulfate and urea in water, uniformly spraying over the mixed material, mixing uniformly, and adding biogas slurry to obtain culture material, (ii) debagging, arranging and soil-covering stage: pouring biogas liquid furrow bed soil into dilute mud paste, closing fungus tube, placing on flat bag surface, stirring and uniformly mixing the loam soil and biogas residue, covering the fungus tube surface, enriching a gap in the fungus gap, and promoting bud growth, (iii) fruiting body differentiation-young mushrooms stages, using mixed nutrition liquid to spray, promoting mushroom fruiting body differentiation and young children mushroom fruiting mushrooms robust growth, and increasing single mushroom weight, where the mixed nutrient liquid comprises biogas slurry and potassium dihydrogen phosphate mixed liquid, and (iv) tide-changing intermittence stage: applying biogas liquid to the case groove poured on bed surface, supplementing fungus tube to consume water, nutrient and mineral elements, and promoting recovery growth of mycelium, where the method combines with the mycelial growth of the spring sowing shiitake mushrooms and the sporocarp differentiation and growth features, hence the nutrient adding process with the biogas residues (slurry) is divided into a dosing and bagging stage, a debagging, arranging and soil-covering stage, a sporocarp differentiation, namely, young mushroom stage and a tide-changing intermittence stage.
