摘要:
以鲜菌草（巨菌草、象草、五节芒）及其相对应的干菌草为试材，采用单因素试验方法，研究鲜菌草与干菌草灭菌前与灭菌后的碳氮含量及碳氮比的变化。结果表明：灭菌前，鲜菌草的碳含量低于相应干菌草的碳含量，鲜菌草的氮含量高于相应干菌草的氮含量，鲜菌草的碳氮比均低于相应干菌草的碳氮比；灭菌后，鲜菌草与干菌草的碳含量和氮含量均有所降低，除了干巨菌草以外，鲜菌草与干菌草的碳氮比均降低，鲜菌草的碳氮比也低于相应干菌草的碳氮比。因此，灭菌对鲜菌草和干菌草的碳含量、氮含量和碳氮比均有影响，鲜菌草更适合用于栽培较低碳氮比的食药用菌。
Abstract:
The purpose of this study is to research the differences of carbon content,nitrogen content and C/N ratio between fresh JUNCAO grass and dry JUNCAO grass before and after sterilization.Fresh JUNCAO grasses,including Pennisetum sinese Roxb,Pennisetum purpureum Schumach and Miscanthus floidulus,and the correspondent dry JUNCAO grasses were used as experimental materials to carry out this research by single factor test method.The results showed that before sterilization,the carbon content of fresh JUNCAO grasses were lower than dry JUNCAO grasses,while the nitrogen content of fresh JUNCAO grasses were higher than dry JUNCAO grasses,and the C/N ratio of fresh JUNCAO grasses were lower than dry JUNCAO grasses.After sterilization,carbon content and nitrogen content of fresh and dry JUNCAO grasses were all reduced,and the C/N ratios of fresh JUNCAO grasses were all lower than dry JUNCAO grasses except for dry Pennisetum sinese Roxb.Therefore,sterilization had effects on carbon content,nitrogen content and C/N ratio of fresh and dry JUNCAO grasses,and fresh JUNCAO grasses were more suitable for cultivating edible and medicinal mushrooms which had lower requirement on C/N ratio.
