本文利用2009—2011年春季单次形成层创伤标记法,对梭梭是否具有可辨识的年轮特征和形成规律进行了实验研究。结果表明:梭梭具有清晰的轮层特征,内侧质地致密、颜色较深,外侧散生大量导管,质地疏松、颜色较浅,与其他树种年轮特征恰好相反;其轮层常不闭合,轮层宽度较为均一;但不具有可辨识的年轮/年层特征,其每年形成轮层数具有区域、个体和单枝不同方向的异质性特征,不宜用于年龄确定和树木年轮学相关领域的研究。 In this paper, the spring traumatic single-layer trapping method from 2009 to 2011 was used to study whether Haloxylon ammodendron possesses recognizable characteristics of annual rings and its formation. The results showed that: Haloxylon ammodendron has clear characteristics of the round layer, the inner texture is dense, darker color, the outer side of a large number of loose tubes, loose texture, lighter color, and other tree ring characteristics exactly the opposite; its layer is often closed, the wheel However, it does not have distinguishable annual / layer characteristics, and it is not suitable for age determination and tree ring-rotation correlation because of the heterogeneity of the number of round layers in different directions of regions, individuals and single branches. Field research.
