福建省牛姆林自然保护区植物繁殖体的热值研究

Caloric values of plant propagules at Niumulin Nature Reserve Zone of Fujian Province

对福建省牛姆林自然保护区18种植物繁殖体(花或果)的热值和灰分含量初步研究结果表明,18种植物繁殖体的灰分含量为21.8～77.4g/kg,平均为46.7g/kg;植物繁殖体具有较高的干物质量热值和去灰分热值(除壳斗科青冈果的干物质量热值和去灰分热值较低外),其余植物繁殖体的干物质量热值为20153.8±50.9～28533.3±37.2J/g,去灰分热值为20900.7～29552.9J/g,植物繁殖体具有较高的热值含量是其功能的具体表现。

The ash contents,gross caloric values and ash-free caloric values in the propagules of 18 plants at Niumulin Nature Reserve Zone of Fujian Province are discussed in this paper.The results show that ash contents in these plant propagules vary from 21.8-77.4g/kg,the average is 46.7g/kg; the plant propagules have the high caloric values,in which gross caloric values and ash-free caloric values vary from 20153.8±50.9J/g to 28533.3±37.2 J/g and from 20900.7J/g to 29552.9 J/g,respectively.Except that gross caloric values and ash-free caloric values of Cyclobalanopsis glauca fruit are both the lowest.High caloric value reflected their functions.
