On
non-supplemented asparagus straw substrate, the yield of P. geesteranus (199 g/bag) was significantly
higher than that of P. abalones (140 g/bag) while the polysaccharides content of P. abalones was significantly
higher than that of P. geesteranus. Addition of appropriate amounts of glucose, MgSO4 and K2HPO4
to the substrate increased the mushroom yield of P. geesteranus significantly. Addition of saccharides and
inorganic salts to the substrate had no remarkable effect on the polysaccharides content of P. geesteranus
fruit bodies, whereas caused the significant decrease of the polysaccharides content of P. abalones fruit
bodies compared with the control. According to th
