缩短香菇生长周期,促成每栽培块菇体都均衡发生,并增加成菇数目和出菇次数,这是国内外一项新的重要研究课题。为此,本文报道选用废纸作培养材料,分析香菇生长周期与菇体生育的研究。一、材料和方法供试菌株香菇7402由上海市食用菌所提供。培养基配方(%):废纸70,麸皮20,谷壳7,蔗糖1,CaSO_41.5,MgSO_40.25,另添加干酵母0.015及1.5马铃薯;含 Shorten the growth cycle of mushrooms, and promote the balance of each cultivated mushroom body, and increase the number of mushrooms and fruiting times, which is a new important research topic both at home and abroad. Therefore, this paper reports the selection of waste paper for culture materials, mushroom growth cycle and fruiting body research. First, the material and method for the test strains Shiitou 7402 provided by the Shanghai mushroom. Medium formula (%): waste paper 70, bran 20, chaff 7, sucrose 1, CaSO_41.5, MgSO_40.25, additional addition of dry yeast 0.015 and 1.5 potatoes;
