沙岸木麻黄林带更新采用木麻黄与湿地松不同比例混交配置 ,木麻黄等树种单行和多行混交造林 ,结果表明 :木麻黄与湿地松带状混交效果较好 ,但需适时适量疏伐 ;木麻黄与刚果 12 # 桉、厚荚相思分别单行混交造林种间关系协调 ,湿地松与刚果 12 # 桉、厚荚相思行状混交易受压 ;不同树种采取多行配置树种间关系良好 ,木麻黄与刚果 12 # 桉处于同一林层 ,厚荚相思分布于木麻黄之下 ,而湿地松与厚荚相思多行混交免遭挤压 ,生长良好
The Casuarina equisetifolia forest belt was replaced by different proportions of Casuarina equisetifolia mixed with Pinus elliottii and mixed tree planting such as Casuarina equisetifolia. The results showed that mixed effect of Casuarina equisetifolia and Pinus elliottii was better, Casuarina equisetifolia and Congo 12 # eucalyptus and Acacia crassicarpa mixed with single plantations, the Pinus elliottii and Congo 12 # eucalyptus and Acacia crassicarpa were easily compressed under the same conditions; And the Congo 12 # Eucalyptus in the same forest, Acacia plicata distributed in the Casuarina, and Pinus elliottii and Acacia mixed with many rows from extrusion, good growth
