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 crassicarpaimprove 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 Casuarinaequisetifoliaon coastal mountain is to plant the mixed stand of several mixed by multi-row or mixture by group of Casuarina equisetifolia + Acacia crassicarpa.
