摘　　要：通过白酒丢糟栽培金针菇的L16(45)正交实验,研究了白酒丢糟培育金针菇的最佳生产条件。结果表明:影响金针菇栽培的主要因素是丢糟前处理方式,其后依次为木屑麸皮添加量、灭菌条件和袋料pH。经过正交实验分析,结合实际生产条件,筛选出的最佳水平组合是A3B4C1D2,即丢糟水洗后压干,袋料pH 7,木屑麸皮添加量30%,灭菌条件为常压10h。在此条件下的金针菇生物转化率为74.9%左右,菌丝生长30d满袋,污染率16.67%。By the method of the L16（45）orthogonal test of cultivating Flammulina velutipes（Fr.）Sing.using spent grains of chinese spirit,the optimum cultivating conditions of Flammulina velutipes（Fr.）Sing.were studied.The results showed that the pretreatment mode of spent grains was the main factor which affected the cultivation,the additive amount of sawdusts and brans was the secondly factor,then was the sterilization condition and pH of culture medium successively on the cultivation of Flammulina velutipes（Fr.）Sing..The optimum cultivating conditions were A3B4C1D2,which was the washed spent grains were pressed to the water content of 45%,pH of culture medium was 7,the additive amount of sawdusts and brans was 30% and the sterilization condition was 10 h on the ordinary pressure.The results showed that the material percent conversion was 74.9%,it took 30 days that polypropylene bags were fulled with hypha,and the contamination rate was 16.67%.
