一、生长特性和分布概况黑松(Pinus thunbergii parlatove)和赤松(Pinus densiflora)为东南亚区松树,常绿乔木,树枝轮生,叶为二针一束。为油松变种,阳性树种,适宜在酸性或中性砂质壤土上生长,山东沿海地区多作为海风林营造。黑松和赤松具有发达的主根及向四周扩展的根系,针叶且具腊质层,并有下陷的气孔,有利于减少蒸腾和对水分的消耗,因此,在其它树种不能生长的干燥脊薄的土地上,它也能生长,耐干旱能力较强,亦是 First, the growth characteristics and distribution of Pinus thunbergii (Pinus thunbergii parlatove) and Pinus densiflora (Pinus densiflora) for the southeast Asia pine, evergreen trees, branches rotate, the leaf is a needle. Pinus tabulaeformis species, positive tree species, suitable for growing in acidic or neutral sandy loam, coastal areas in Shandong as the sea wind forest to create. Black pine and red pine have developed main roots and all around the expansion of the root system, coniferous and waxy layer, and subsidence of the pores, is conducive to reducing transpiration and water consumption, therefore, in other species can not grow dry ridges It also grows well with drought-resistant capacity, too
