摘要
研究了1997年1月福建省华安县绿竹(Dendrocalamopsisoldhami)林各组分的热值、能量现存量;1996年7月至1997年6月绿竹叶与细根分解过程的热值变化.结果表明:1)1997年1月绿竹林各组分的灰分含量有较大差异,在3.82%~17.66%之间,杆的灰分含量最低,叶的灰分含量最高;干重热值在16625.5~18648.2J/g之间,细根的干重热值最低,杆的干重热值最高.2)1996年7月至1997年6月绿竹叶的干重热值有一定的季节变化,干重热值在冬季最低.3)1996年7月至1997年6月绿竹细根分解过程中干重热值呈现上升、而后逐渐下降的趋势.
A study on energy of Dendrocalamopsis oldhami forest in Huaan county of Fujian province was made in this paper. The results were as follows: (1)The ash content of different fractions in Dendrocalamopsis oldhami forest in January 1997 was from 3.82% to17.66%, in which the ash content of stems was the lowest and that of leaves was the highest. The gross caloric value was the lowest for fine roots and the highest for stems.(2)The gross caloric value of Dendrocalamopsis oldhami leaves form July 1996 to June 1997 changed with season, in which the gross caloric value in winter was the lowest. (3)During the decomposition of fine roots, the gross caloric value had the tendency for increasing , and then decreasing
