摘 要:对福建省宁化县20年生的火炬松与马尾松混交试验林的生长量进行调查分析,结果表明:在相同立地因子和相同经营措施条件下,火炬松与马尾松混交林的生长量与火炬松纯林、马尾松纯林的生长量间具有极显著差异。在不同混交方法中,以带状混交林的生长量最大,林分总蓄积量达166.023 m3.hm-2;块状混交林次之;株间混交林最小。在不同混交比例中,以火炬松∶马尾松=8∶2混交林和火炬松纯林的生长量较高,林分总蓄积量分别达164.277 m3.hm-2和161.217 m3.hm-2,马尾松纯林的生长量最小。20-year-old loblolly pine and masson pine mixed forest growth amount was investigated in Ninghua,the results showed that:in the same conditions of the same site factors and management measures,loblolly pine,mixed forest and pine pure forest growth amount had a very significant difference,in the different methods of mixed forest,strip mixed forest growth was the largest,the total accumulated volume of stand reached 166.023 m3·hm-2,followed by massive mixed forest,mixed forest among the trees was the smallest.By different mixed ratios,and pure forest plantation and mixed plantation(loblolly pine∶ pine ratio=8∶ 2)had the highest growth amount,the total stand stocking,respectively reached 164.277 m3·hm-2,and 161.217 m3·hm-2,tests showed that loblolly pine was suitable for the local afforestation.
