| 摘 要： | 研究了闽南绿竹林的营养元素P、K、Na、Ca、Mg的含量特征以及1996年7月至1997年6月一年中绿竹叶营养元素含量的变化。结果表明:(1)这5个营养在绿竹林各组分中,P的含量最低,K的含量最高:(2)1996年7月至1997年6月一年中各月绿竹叶的营养元素含量大小基本上是K>Ca>Mg>Na>P(97年4月至6月绿竹叶的Mg>Ca除外);(3)1997年1月绿竹林P、K、Na、Ca、Mg的库存量分别为0.820、70.525、6.783、12.275、9.564g/m2。

| Abstract: | This paper dealt mainly with the monthly changes of nutrient elements (P,K,Na, Ca,Mg) of leaves from July 1996 to June 1997, in addition with the contents of nutrient ele-ments in Dendrocalamo psis oldhami forest in January 1997 in South of Fujian Province. The re-sults were as follows: (1) The content of Potassium was the highest, that of Phosphorus was the lowest in the different fractions of D. oldhami forest. (2) The order of content of nutrient ele-ments of leaves from July 1996 to June 1997 was K>Ca>Mg>Na>P, with the exception of the order (Mg>Ca) from April 1997 to June 1997. (3) The pool amounts of five nutrient ele-ments in D. oldhami forest was 0. 820g/m2 for P, 70. 525g/m2 for K, 6. 783g/m2 for Na, 12. 257g/m2 for Ca and 9. 564g/m2 for Mg, respectively. |
