竹废弃物基质栽培对大球盖菇农艺性状及品质的影响OA

[Objective]To optimize the substrate formula for the cultivation of Stropharia rugosoannulata.[Method]Utilizing waste materials from three bamboo species(Phyllostachys edulis,Phyllostachys praecox,and Bambusa multiplex)including bamboo branches,leaves,tips,and residues from bamboo pole processing as cultivation materials for S.rugosoannulata,three bamboo sawdust ratios(68%,78%and 88%)were set up.By observing mycelial growth and fruiting time,the agronomic traits and nutritional components of S.rugosoannulata were com-pared to study the effects of different substrate ratios on the growth and quality of the mushroom.[Result]Bamboo forests produce over 70%waste materials;the carbon-nitrogen ratio of bamboo sawdust ranges from 48.00 to 53.21,with P and Mg content ranging from 0.47 to 1.33 mg/g,and K and Ca content ranging from 1.66 to 3.38 mg/g,indicating a rich content suitable for the growth of S.rugosoannulata;un-der the cultivation conditions using B.multiplex sawdust,the content of crude protein(378.2 g/kg)and crude polysaccharides(186.0 g/kg)in S.rugosoannulata was the highest,with the largest proportion of high-quality mushrooms,reaching 44.75%.[Conclusion]Bamboo sawdust is suitable for the cultivation of S.rugosoannulata,with B.multiplex sawdust showing the best cultivation effects,effectively improving the nu-trition and yield of the mushroom,and effectively extending the industrial chain of the bamboo forest ecosystem.
