摘要/Abstract

摘要：

对5年生黑杨无性系的冠层特性与材积生长之相关性进行了研究。材积生长与全树总叶面积TLA、树冠表面积TCA和冠型率CSR呈极显著正相关而与叶面积指数LAI、冠层密度CLD呈负相关。冠层内上、中层的叶面积对材积生长起了决定性作用,下层叶面积与材积生长关系不大。水平方向,冠层内、外部叶面积特性对材积生长贡献较大,而中部叶面积特性贡献小。阐明了杨树生长的理想冠层特性。

Abstract:

The relationship between crown characteristics and stemwood growth was explored based on the investigation of 12 five-year-old poplar hybrid F₁ clones.The stemwood growth (D ² H) was positively related to total leaf area (TLA), surface area of crown (TCA) and crown shape ratio (CSR), but negatively related to leaf area index (LAI) and crown layer density (CLD).In the vertical distribution of crown foliage, the upper and middle layers were the determinants on stemwood growth, while in the horizontal distribution, the inner and outer parts had great contributions on stemwood production.In the end of this paper, a reasonable crown characteristics structure for this poplar population was outlined.
