摘要
在东山县山地开展木麻黄+厚荚相思1∶1和3∶3混交造林试验,结果表明:木麻黄+厚荚相思混交促进了木麻黄胸径、材积生长,提高了林分单位面积的总蓄积量;削弱了林内风速,增强了林分的防风效能;增加了土壤的养分,改善了地力。木麻黄+厚荚相思按3∶3的比例混交对于提高木麻黄生长量、防风效能和土壤肥力的效果更加明显。沿海山地木麻黄造林以营造木麻黄+厚荚相思多行或块状混交林为宜。
The mixed afforestation experiment of Casuarina equisetifolia+Acacia crassicarpa(1∶1&3∶3)was conducted on mountain of Dongshan County.Result shows that the mixed forest of Casuarina equisetifolia+Acacia crassicarpa improve the growth of DBH and volume,increase the total growing stock,weaken the wind speed,increase the soil fertility,increase the soil nutrient and improve the soil fertility.Mixed forest of Casuarina equisetifolia+Acacia crassicarpa(3∶3)has outstanding effect on the growth,wind speed reduction effect&soil fertility.The suitable afforestation of Casuarina equisetifolia on coastal mountain is to plant the mixed stand of several mixed by multi-row or mixture by group of Casuarina equisetifolia+Acacia crassicarpa.
