摘　　要：湿加松良种‘中林1号’是从国外引种经区域化试验后选出的优良无性系,其母本为湿地松(Pinus elliotti),父本为加勒比松洪都拉斯变种(P.caribaea var.hondurensis)。‘中林1号’速生性突出,其6年生和10年生平均材积均超过对照母本湿地松35%以上。‘中林1号’干形通直,尖削度小,冠幅紧凑。湿加松‘中林1号’扦插繁殖容易,可采用嫩枝扦插育苗且造林成活率高。其木材基本密度0.414 g/m^3,木质素含量29.61%,综纤维素含量69.49%,α-纤维素含量41.56%,适用于建筑材、板材、纸浆材等工业用原材料。The hybrid pine ‘Zhonglin 1’ was a fine clone which was introduced from abroad and selected after regional trial. Its female parent was Pinus elliottii and male parent was Pinus caribaea var. hondurensis. The ‘Zhonglin 1’ was a fast-growing clone. Average volume of the ‘ZhongLin 1’ both 6-year-old and 10-year-old were all more over 35% than the control variety slash pine. ‘Zhonglin 1’ has a strait and round trunk, a little tapering grade and crown. It was easily propagated with high survival rate by green cuttings. Its basic density was 0.414 g/m^3, lignin content was 29.61%, holocellulose content was 69.49% and alpha-cellulose content was 41.56%.
