酱香型白酒糟对金针菇菌丝生长及子实体性状的影响

Effects of Moutai-flavor Liquor Distiller's Grains on Mycelial Growth and Fruit Body Traits of Flammulina velutipes

针对近年来金针菇主要栽培原料棉籽壳价格不断上涨且紧缺的问题，用酱香型白酒糟部分替代棉籽壳，设计以酱香型白酒糟添加量在20％-70％，依次递减的6个栽培配方，以棉籽壳为主要栽培料配方为对照（CK），进行金针菇栽培试验。结果表明，处理D（40％酱香型白酒糟）虽然菌丝生长速度、产量与对照CK相比差异不明显，但酱香型白酒糟的添加可以显著降低原材料成本，提高经济效益。

The cotton seed hull as the main cultivation material of Flammulina velutipes, are shortage and its market price is in- creasing fast, moutai-flavor liquor distiller＇s grains were used to partly replace cotton seed hull in our study. We created six new substrate formula containing 20%-70% moutai-flavor liquor distiller＇s grains to cultivate F. velutipes, taking the normal formula CK that based on cotton seed hull as the main componet. The results showed that between the fomula D and the CK, the production is equivalent as well as growth rate, but the fomula D could significantly reduce the cost and increase the benefit.
