摘要
在福建农林大学百竹园内随机选取3个竹种:歪脚龙竹、坭竹、长叶苦竹,分别于春、夏、秋、冬4个季节对其叶片、主枝、小枝的硫含量进行测定,同时以福州市森林公园相同竹种作为参照。结果表明:竹类植物叶片硫元素含量最高,各竹种之间硫元素含量差异显著;同竹种不同季节的各部位的硫含量均有变化,秋季硫含量最高,夏季最低,较秋季平均减少54.88%;竹类植物对于硫元素的吸收作用较强,叶片硫含量均高于国标的最高值2.0 g.kg-1,且叶片硫含量对环境二氧化硫变化具有指示作用,可以考虑作为硫污染区的绿化植物。
Choosing 3 kinds of bamboo samples incluing Dendrocalamus sinicus,Bambusa gibba,and Pleioblastus chino in Fujian Agriculture and Forestry University,this paper determined on the amount of sulfur of the different parts of the bamboos for 4 seasons.Meanwhile,the same bamboos in Fuzhou Forest Park were took as the samples.Statistical analysis showed that the content of sulfur of leaves was highest,and the sulfur content between different bamboos was significantly different,the sulfur content in different seasons had obvious changed even if in the same bamboo,it manifested that the content in autumn was the greatest than other seasons,and had a decrease of 54.88% on average.Bamboo had a strong absorption capacity for the sulfur,which leaf sulfur content was higher than the highest GB value 2.0 g.kg-1,and it could be widely planted in the sulfur dioxide pollution area.
