3个木麻黄品系不同混交模式在海岸退化防护林修复中的应用研究

Study on the Application of Different Mixed Modes of Three Casuarina equisetifolia Strains in the Restoration of Coastal Degraded Shelter Forest

为修复强风区域海岸退化防护林带,同时提升防风效能,选择抗性优良的3个木麻黄品系,运用不同的混交模式对其生长指标及防风效能进行分析。结果表明:在3个木麻黄品系均参与的混交模式中,3个木麻黄品系的保存率均最高,生长指标除圆头木麻黄外,“惠-1”木麻黄和千头木麻黄均最高;防风效能方面,3个木麻黄品系均参与的混交模式中,在不同高度的防风效能均最高,该混交模式可以在海岸退化防护林修复中进行推广应用。

In order to restore the strong wind areas in the coastal degraded shelter belt and improve the windproof efficiency,three Casuarina equisetifolia strains with good resistance were selected and their growth indexes and windproof efficiency were analyzed by using different mixed models.The results showed as follows:in the mixed mode in which all the three Casuarina equisetifolia strains participated,the preservation rates of the three Casuarina equisetifolia strains were the highest,and the growth indexes of Casuarina equisetifolia‘hui-1’and Casuarina equisetifolia‘qiantou’were the highest except for Casuarina equisetifolia‘yuantou’;in the aspect of wind protection efficiency,the windproof efficiency of the three Casuarina equisetifolia strains at different heights was the highest in the mixed mode,which could be popularized and applied in the restoration of coastal degraded shelter forest.
