【摘要】 以沼液为试验材料,研究了不同浓度沼液拌料对平菇菌丝生长、产量的影响。结果表明,沼液能改善培养料的营养,用25%、50%沼液拌料可促进平菇菌丝体的生长,菌丝生长势增强,污染率降低,产量分别比对照高23.5%、15.8%;用75%、100%沼液拌料也可降低污染率,平菇产量分别比对照高24%、8.7%,但菌丝的生长速度降低,出菇时间比对照晚4d13d。
【Abstract】 The effect of biogas slurry of different density on the growth and yield of Pleurotus ostreatus were studied. The results showed that biogas slurry could improve the nutrition of the cultivation material, the growth rate of Pleurotus ostreatus mycelium were accelerated using 25% or 50% biogas slurry, the growth vigor were strengthened, and the yield increased by 23.5% or 15.8% compared with CK. Using 75% or 100% biogas slurry can lower the contamination rate, and increase the yield by 24% or 8.7%, but the growth rate of mycelium slow down and the mushroom budding was comparatively 4 d13 d late.
