3种南方防火树种理化性质的试验研究

以火力楠、木荷、油茶3种防火树种为研究对象,对各季节3种防火树种树枝、树皮、树叶的含水率、燃点、热值、灰分含量、粗脂肪含量、木质素含量、粗纤维含量等理化性质进行测定分析,以评估不同树种在不同季节的燃烧性。结果表明:各季节3种防火树种树枝、树皮、树叶的含水率、燃点、灰分含量和木质素含量总体为木荷>油茶>火力楠;热值春季为油茶>木荷>火力楠,秋冬两季为火力楠>油茶>木荷;粗脂肪含量各季节均为火力楠>油茶>木荷;粗纤维含量各季节均为油茶>火力楠>木荷。研究结果为3种防火树种的防火效能分析提供数据支持。

Experimental Research on Physical and Chemical Properties of Three Fire-prevention TreeSpecies in South China

Taking Michelia macclurel,Schima superba Gardn.et Champ and Camellia oleifera Abel as the research objects,the physical and chemical properties such as moisture content,ignition point,calorific value,ash content,crude fat content,lignin content and crude fiber content of the branches,bark and leaves of the three fire-prevention tree in different seasons were determined and analyzed to evaluate the combustibility of the tree species.The results showed that the moisture content,ignition point,ash content and lignin content of tree branches,bark and leaves of the three fire-prevention tree from large to small was Schima superba Gardn.et Champ,Camellia oleifera Abel,and Michelia macclurel.The calorific value from large to small was Camellia oleifera Abel,Schima superba Gardn.et Champ and Michelia macclurel in spring,Michelia macclurel,Camellia oleifera Abel and Schima superba Gardn.et Champ in autumn and winter.The crude fat content from large to small was Michelia macclurel,Camellia oleifera Abel and Schima superba Gardn.et Champ in every season.The crude fiber content from large to small was Camellia oleifera Abel,Michelia macclurel,and Schima superba Gardn.et Champ in every season.The results provide data support for the analysis of fire prevention efficiency of three fire-prevention tree.
