滇中地区13种常见蕨类植物燃烧性研究

Combustibility of 13 Common Pteridophytes in Central Yunnan

为探究滇中地区蕨类植物的燃烧性,以滇中地区13种常见蕨类植物为研究对象,测定其灰分含量、热值以及粗脂肪含量3项理化性质。根据其理化性质计算其燃烧性综合指数,进而评价其燃烧性并进行分类。结果表明,13种蕨类的灰分含量、热值以及粗脂肪含量范围分别在4.20%~8.86%、17635~22170 J/g和4.20%~8.96%范围,平均值分别为7.10%、20332.77 J/g以及6.66%;燃烧性最好的一类为金粉蕨和肾蕨,燃烧性中等的10种蕨类植物从强到弱顺序为凤尾蕨、云南耳蕨、基生鳞毛蕨、狗背蕨、鲜蕨、毛轴蕨、毛蕨、疏羽蹄盖蕨、芒萁、粗齿鳞毛蕨,近鳞轴小膜盖蕨燃烧性较差。

In order to explore the combustibility of pteridophytes in central Yunnan,13 common pteridophytes in central Yunnan were selected to determine ash content,calorific value and crude fat content.According to the physicochemical properties,the comprehensive combustibility index was calculated,and then the combustibility was evaluated and classified.The results showed that the ash content,calorific value and crude fat content of 13 species of pteridophytes ranged from 4.20%to 8.86%,17635 to 22170 J/g and 4.20%to 8.96%respectively,and the average values were 7.10%,20332.77 J/g and 6.66%respectively;the best combustible species were Onychium japonicum and Nephrolepis auriculata,and the order of 10 species of pteridophytes with moderate combustibility from strong to weak was Pteris creticanervosa,Polystichum yunnanense,Dryopteris basisora,D.erythrosora,D.ceae,Pteridium revolutum,Cyclosorus interruptus,Athyrium nephrodioides,D.dichotoma and D.juxtaposita Christ,and Araiostegia perdurans with poor combustibility.
