| 摘 要： | 通过对比栽培试验分析,选择出适宜章固台沙地造林应用的乡土树种刺榆(Hemiptelea davidii)、小叶朴(Celtes Bengeana)、黑桦(Betulasp.),外来树种铅笔柏(Sabina virginiana)和新疆大叶榆(Ulmus laevis)等造林树种。乡土树种在极端气候条件下没有出现任何干枯死亡现象,表现稳定。刺榆的生长量超过大果榆和家榆,小叶朴和桦树也表现出适应性强的特性。引种的外来树种,铅笔柏和新疆大叶榆,虽然在前2～3年发生枯梢现象,但总生长量已超过或接近对照树种,可以在营造混交林中应用。刺榆和铅笔柏选出了不同形态类型,经过不断选择,选育出具有不同形态的树木,可以在不同目的造林中应用。

| Abstract: | Through analysis of cultivation experiments,native tree species(Hemiptelea davidii,Celtes bengeana,Betula sp.),exotic species(Sabina virginiana and Sabina virginiana) were selected.Native species did not appear of any dry & deaths phenomenon in extreme weather conditions and performed stability.Growth of Hemiptelea davidii exceeds Ulmus macrocarpa and Ulmus pumila;Celtes bengeana & Betula sp.show stronger adaptability characteristics.Die-back phenomenon of Sabina virginiana & Ulmus laevis(introduced exotic species) occurred during the first two to three years,however,the total growth is more than or close to control species;these two species can be applicated in silviculturing mixed forest.With continuous selection,different forms of trees of Hemiptelea davidii & Sabina virginiana were selected for applying in planting for different purposes. |
