棉籽壳基质在P.ostreatus生长过程中组份与rn微结构的变化及其对菌糠饲用价值的影响

摘要

The dry matters and contents of major compositions of cottons e ed hull substrate for P. ostreatus cultivation were tested at different grow ing stages. The micro-structures of the substrate were observed under scanning electronic microscopy(SEM). Their effects on the feed nutritional values of the spent substrate were investigated. During the whole P. ostreatus growing per iod, the content of protein, cellulose, hemicellulose, lignin, and the micro-st ructures of the substrate were changed considerably. These contributed to the raising of the dr y matter digestibility of the spent substrate, making it possibly acceptable to be used as ruminant feed with improved feed value.%对棉籽基质在栽培P.ostreatus过程中不同时期的干物质及主要组 份含量进行了测定。对其微观结构的变化进行了显微观察。分析了组份与微观结构的变化对 菌糠饲用价值的影响。结果表明：与初始料相比，菌糠具有较高的干物质消化率，因而有可 能用作反刍动物的饲料。
