黑木耳是一种食用和药用价值很高的食用菌.近年来,国内采用代料栽培已获得成功.据报道,木屑栽培的生物学效率为50～70%;棉籽壳栽培的生物学效率为60～80%,蔗渣栽培的生物学效率只有30%左右,产量很低.为了充分利用我省丰富的蔗渣资源,提高蔗渣栽培黑木耳的产量,我们对蔗渣袋栽黑木耳的配方做了研究,并获得了显著效果.试验结果,蔗渣92%、麦麸5%、白糖1%、碳酸钙1%、尿素0.5%组的产量最高,平均生物学效率达84.1%,比不加尿素的蔗渣常规配方组增产15.0%,比木屑组增产92.0%,增产效果更为显著.从新配方试验结果表
Black fungus is a kind of edible and medicinal valuable edible fungi.In recent years, the domestic use of sub-planting has been successful.According to reports, the biological efficiency of sawdust cultivation is 50 ~ 70%; cottonseed cultivation biological efficiency Is 60 ~ 80%, the biological efficiency of bagasse cultivation is only about 30%, the yield is very low.In order to make full use of the rich bagasse resources in our province and improve the yield of bagasse cultivated black fungus, we made the bagasse bag black fungus formula The results showed that 92% of bagasse, 5% of wheat bran, 1% of white sugar, 1% of calcium carbonate and 0.5% of urea had the highest yield and average biological efficiency of 84.1% Bagasse conventional formula group increased 15.0%, 92.O% increase than sawdust group, the yield increase effect is more significant.From the new formula test results table
