章古台沙地针叶树引种造林试验

Field Performance of Introduced Conifers in Zhanggutai Sandy Area, Liaoning Province

报道了长白松（Ｐｉｎｕｓ ｓｙｌｖｅｓｔｒｉｆｏｒｍｉｓ）、班克松（Ｐｉｎｕｓ ｂａｎｋｓｉａｎａ）、小干松（Ｐｉｎｕｓ ｃｏｎｔｏｒｔａ）、黑云杉（Ｐｉｃｅａ ｍａｒｉａｎａ）、白云杉（Ｐｉｃｅａ ｇｌａｕｃａ）、红皮云杉（Ｐｉｃｅａ ｋｏｒａｉｅｎｓｉｓ Ｎａｐａｌ）、辽东冷杉（Ａｂｉｅｓｈｏｌｏｐｈｙｌｌａ Ｍａｘｉｍ）、樟子松（Ｐｉｎｕｓ ｓｙｌｖｅｓｔｒｉｓ）８种针叶树引种到章古台沙地８ａ后的试验结果。重点对各树种的树高、地径、保存率等进行了分析研究。结果表明：班克松在生长量（树高、地径）、保存率方面表现最佳．其高生长超过对照（樟子松）７４％；在抗虫性方面．以云、冷杉表现最佳。到目前没有发现病虫危害。

Trees of & coniferous species. namely Pinus sylvestriformis, P. contorta. P. contorta. Picea mariana. P. glauca. P. koraiensis. Ables holophylla. Pinus sylvestris L. var. mougolica. were planted out in Zhanggutai sandy area. Here is the presentation of & years result in tree height. ground collar diameter and survival rate. Pinus banksiana was the best in both growth and survival rate. whose height was 74% higher than that of Pinus sylvestris var. mongolica. Trees of Picea and Ables were free of disease and pests.
