Abstract:

In order to solve the problem that so much waste materials of Auricularia auricula is not effectively used in Heilongjiang Province, we actively explored new technologies for Hohenbuehelia serotina cultivation, with the traditional formula CK cultivated species as control, 12% germ bran in place of chips designed for concentration gradient gradually 6 cultivar formula, equal growth of inoculated seed, bacteria and mushrooms were cultivated under the same conditions. By determination of pleurotus citrinopileatus mycelium growth potential, full bag, primordia formation time, conditions, fruiting of pleurotus and conversion efficiency of biological growth method, examined the effects of different concentration of germ bran in cultivation mushroom growth cycles, biological effects of efficiency and quality. Results indicated that, when the cultivated species composition contains 36% fungus chaff, 44% sawdust, 17% wheat middlings, 1% soybean flour, 1% corn flour and 1% calcium carbonate, Hohenbuehelia serotina grew well. Hyphae grew thick and strong, biological conversion efficiency of 81.96%, 1.74% higher than the control, experiment proved that a fungus germ bran cultivated mushroom was feasible.
