【中文摘要】 為降低香菇栽培對闊葉樹資源的消耗 ,本文研究了不同栽培基質配方原始組分含量、呼吸消耗、基質失重對絕對生物學效率的影響及不同生育階段木質纖維素的生物降解規律。結果表明 ,經優化配比的節木栽培基質 ,發菌階段呼吸消耗失重率為 16 4 4 %～ 17 12 % ,出菇階段木質素降解率為 73 83%～ 78 2 4 % ,整個生育過程木質纖維素降解率為 78 0 9%～ 79 77% ,絕對生物學效率為 10 2 2 %～ 11 4 1% ;節木栽培基質木質素的降解主要發生在出菇階段 ,其降解率越高 ,絕對生物學效率越高 ,但木質素的降解率并不隨木質素含量的升高而提高 ;木質素的降解尚需外源較易利用的碳源啟動
【英文摘要】 In order to reduce broad-leaf tree resource consumption in shiitake culture substrate,we have adopteddifferent culture substrates for a study of the influence to absolute biological efficiency by original composition content,respiration consumption and weight loss of substrate and bio-degeneration law of lignocellulose during different growing stages.Result indicates that for the optionally matched sawdust-saving substrate,its weight loss ratio because of respiration consumption in spawn growing stage is 16 44%～17 12%,lignin degeneration ratio in mushroom growing stage is 73 83%～78 24%,lignocellulose degeneration ratio during the whole growing process is 78 09%～79 77%,absolute biological efficiency is 10 22%～11 41%,lignin in sawdust-saving culture substrate mainly degenerates in mushroom growing stage;The higher the degeneration ratio,the higher its absolute biological efficiency.However,lignin degeneration ratio does not go up with more lignin content.Lignin degeneration needs to be i...更多nitiated with an easily accessible out-side carbon source. 還原
