采用木麻黄分别与刚果 12号桉树、厚荚相思单行配置 ,木麻黄纯林为对照 ;湿地松分别与刚果 12号桉树、厚荚相思单行配置 ,湿地松纯林为对照进行木麻黄基干林带改造试验。对 2年生幼林观测表明 ,防风固沙能力大小依次为木麻黄与刚果 12号桉树混交林 >木麻黄与厚荚相思混交林 >木麻黄纯林 ;湿地松与刚果 12号桉树混交林 >湿地松与厚荚相思混交林 >湿地松纯林。木麻黄的生长量表现为木麻黄与厚荚相思混交 >木麻黄与刚果 12号桉树混交 >木麻黄纯林 ;湿地松的生长量表现为湿地松与厚荚相思混交 >湿地松纯林 >湿地松与刚果 12号桉树混交。湿地松与刚果 12号桉树单行配置受到刚果 12号桉树的挤压
The results showed that Casuarina equisetifolia and Casuarina equisetifolia were the control of Casuarina equisetifolia and Casuarina equisetifolia respectively. Casuarina equisetifolia and Casuarina equisetifolia were used as control test. Observations on 2-year-old young forest showed that the ability of windbreak and sand fixation was Casuarina equisetifolia mixed with Congo 12> Mixed forest of Casuarina equisetifolia> Pure plantation of Casuarina equisetifolia; mixed plantation of Pinus elliottii and Congo 12 Eucalyptus> Acacia thick mixed forest> Pinus elliottii forest.
