研究植物各器官营养元素含量及变化,对于揭示植物对营养元素的需要、不同器官营养的分配以及植物对环境的适应能力具有重要的意义。以新疆轮台县轮南镇5个林龄胡杨林(幼龄林、中龄林、近熟林、成熟林和过熟林)为对象,分析枝、叶及根的C、N、P含量及化学计量特征。结果表明:(1)不同器官间C、N含量差异显著,C含量枝(464.70g·kg^(-1))>叶(443.35g·kg^(-1))>根(420.31g·kg^(-1));N含量叶(13.56g·kg^(-1))>枝(4.00g·kg^(-1))>根(3.49g·kg^(-1));器官间P含量差异不显著,根(3.04g·kg^(-1))>叶(2.84g·kg^(-1))>枝(2.34g·kg^(-1))。林龄对胡杨叶的C含量有显著影响(P枝(117.86)>叶(33.28),C∶P比表现为枝(227.14)>叶(178.49)>根(154.23),N∶P比表现为叶(5.29)>枝(1.90)>根(1.29);林龄对枝的C∶P和N∶P影响显著(P<0.05),而对其他器官的化学计量特征影响不显著。(3)胡杨叶的N∶P比为5.29,远远小于阀值(14),说明该地区胡杨生长发育过程中严重受全N影响。
