2、测定仪测定了不同坡度、坡位和坡向的高节竹(Phyllostachysprominens)1~3年生立竹的叶片叶绿素值,研究主要环境因子对高节竹叶片叶绿素含量的影响。结果表明:随立竹年龄的增大,高节竹叶片叶绿素值总体呈升高趋势,2、3年生立竹叶片叶绿素含量显著高于1年生立竹;坡度对上坡位、中坡位2、3年生立竹的叶片叶绿素值影响明显,而对1年生立竹和下坡位立竹影响并不明显,总体上随坡度的增大叶片叶绿素值减小;随坡位的升高,叶片叶绿素值总体呈下降趋势,坡位对1年生立竹的叶片叶绿素值影响不明显,对2、3年生立竹的叶片叶绿素值
3、的影响随坡位的升高而趋于显著;阳坡立竹的叶片叶绿素值总体上高于阴坡,坡向对1年生立竹的叶片叶绿素值无明显影响,但对2、3年生立竹总体上有显著影响。说明坡向、坡度、坡位主要影响2、3年生立竹的叶片叶绿素值,宜选择缓坡地和陡坡地阳坡面的下坡位进行高节竹林高效栽培。关键词:高节竹;SPAD值;立竹年龄;坡度;坡位;坡向中图分类号:S718.43文献标识码:BAnalysisontheMainInfluencingFactorsofChlorophyllValueinLeavesofPhyllostachysprominen
