沿海木麻黄基干防护林带多树种配置改造试验

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

EXPERIMENT ON TRANSFORMATION OF THE TRUNK SHELTERBELT OF CASUARINA EQUISETIFOLIA BY MIXING OF MORE SPECIES

The transformation experiment of trunk shelterbelt of Casuarina equisetifolia was conducted using single row planting: mixing Casuarina equisetifolia , respestively, with Eucalyptus 12ABL and Acacia crassicarpa A cunn ex Benth, Pure stand of casuarina equisetifolia was the check; mixing slash pine, respeatively, with Eucalyplus 12ABL and Acacia crassicarpa A cumm ex Benth, and pure stand of slash pine was the check Observing at 2 aegs of young growth indicated, that the abilities of wind protection and dune fixation are: mixing Casuarina equisetifolia with Eccalyaptus 12ABL > mixing Casuarina equisetifolia > pure forest of Casuarina equisetifolia ; minxing shash pine with Eucalyptus 12ABL > mixing shash pine with Acacia crassicarpa A cunn ex Benth > its mixing with Eucalyplus 12ABL > its pure forest
