摘要
以四川4个地区两种丛生竹慈竹和硬头黄为材料,对其木质素含量和G与S比值进行研究的结果表明,4个地区木质素含量均为慈竹高于硬头黄,多数地区竹种间木质素含量的差异不大。在所有地区中,以三台慈竹木质素含量最高,长宁最低;而硬头黄木质素含量以三台地区含量最高,青神最低。同一地区硬头黄G/S值较慈竹低。不同地区中以绵阳硬头黄G/S值最低,其次是长宁慈竹、青神硬头黄和青神慈竹。长宁地区种植的慈竹、绵阳及青神种植的硬头黄对造纸较适合。
The lignin content and ratio of G with S in Neosinocalamus affinis and Bambusa rigida from four different regions in Sichuan province were studied. The results showed that the lignin Neosinocalamus affinis was higher than that of Bambusa rigida in four different regions. content of But the difference of lignin content between Neosinocalamus affinis and Bambusa rigida were not significant in more regions. The highest content of lignin was Neosinocalamus affinis in ST, the lowest was in CN. The lignin content of Bambusa rigida in ST was the highest, the lowest was in QS. The ratio of G with S in Bambusa rigida from the same region was lower than in Neosinocalamus affinis. The lowest ratio of G with S in Bambusa rigida in the different regions was founded in MY. There was the lower ratio of G with S in Neosinocalamus affinis from CN and QS and in Bambusa rigida from QS. Neosinocalamus affinis in CN and Bambusa rigida in MY and QS were suitable for making - pulp.
