利用平菇菌糠栽培双孢蘑菇高产配方筛选研究

摘要

为筛选以平菇菌糠和牛粪为主要原料栽培双孢蘑菇的最佳配方，设主料菌糠与牛粪质量比〔m （菌糠）∶m（牛粪）〕5∶5（处理Ⅰ）、6∶4（处理Ⅱ）、7∶3（处理Ⅲ）、8∶2（处理Ⅳ）和9∶1（处理Ⅴ）5个处理，以尿素、过磷酸钙和石膏为辅料，研究了菌糠与牛粪不同质量配比对培养料发酵情况、菌丝生长情况以及鲜菇产量的影响。结果表明：以平菇菌糠和牛粪为主要原料栽培双孢蘑菇时，菌糠与牛粪的最佳质量比为6∶4。该配比下，培养料发酵温度上升较快，发菌速度和菌丝生长速度快，菌丝长势最好，现蕾密度最大，产量最高，达到了11．80 kg／hm2。%In order to screen the optimal formula for cultivation of Agaricus bisporus using spent pleurotus substrate and dry cow dung as the main materials, the mass ratios of fungus chaff and cow dung were conducted by 5∶5, 6∶4, 7∶3, 8∶2, 9∶1, respectively, and the urea, superphosphate and gypsum were taked as accessories, then the effects of different mass ratios of fungus chaff and cow dung on fermentation, growth of mycelium and fresh mushroom yield were studied.The results showed that when Agaricus bisporus cultivated with spent pleurotus substrate and dry cow dung as the main materials, the optimum mass ratio of fungus chaff and cow dung was 6∶4.In the condition, fermentation temperature of culture rose faster, the fungus sped and mycelium grew rapidly, the density was maximum, the yield of fresh mushroom was highest, it reached 11.80 kg/hm2.
