摘要: 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(464.70 g·kg-1)>叶(443.35 g·kg-1)>根(420.31 g·kg-1);N含量叶(13.56 g·kg-1)>枝(4.00 g·kg-1)>根(3.49 g·kg-1);器官间P含量差异不显著,根(3.04 g·kg-1)>叶(2.84g·kg-1)>枝(2.34 g·kg-1)。林龄对胡杨叶的C含量有显著影响(P<0.05)。(2)不同器官化学计量差异显著,C:N比表现为根(123.67)>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。

Abstract: Studying the nutrient element contents and their variations of different organs of the plant living in extreme environments is very important to reveal the need of nutrient elements and the nutrient distributions of different organs for the plant, and it is also necessary to show the plant's adaptive and feedback capacities to extreme environments. Taking five different aged Populus euphratica forests (young, middle aged, near mature, mature and over-mature) in Lunnan town, Luntai county, Xinjiang as research subjects, the C, N ,P contents in leaves, breaches and roots of Populus euphratica were measured, and their stoichiometric characteristics were analyzed. The results indicated that: (1) there was a significant difference in the C and N contents of different organs, the contents of C and N were, breaches (464.70 g·kg-1)>leaves (443.35 g·kg-1)>roots (420.31 g·kg-1), leaves(13.56 g·kg-1)>breaches (4.00 g·kg-1)>roots (3.49 g·kg-1). There was no significant difference for P contents at different organs, which was roots (3.04 g·kg-1)>leaves (2.84 g·kg-1)>breaches (2.34 g·kg-1). Forest age had a significant effect on C contents of leaves, but a small influence on nutrient elements of different organs. (2) the difference among the stoichiometry of different organs was remarkable, the ratios of C:N, C:P and N:P were, roots (123.67)>breaches (117.86)>leaves (33.28), breaches (227.14)>leaves (178.49)>roots (154.23), leaves (5.29)>breaches (1.90)>roots (1.29). Forest age had a significant effect on the ratios of C:P and N:P of breaches, but a little effect on the ratios of stoichiometry of different organs. (3) The ratios of N:P of leaves was 5.29, which was much less than the threshold value, showing that the growth of Populus euphratica in this area was greatly influenced by total N.
Key words: Populus euphratica    ecological stoichiometry    forest age    organs
