| 摘 要： | 张掖市甘州区兔儿坝滩是河西走廊北部生态屏障的重要地段,气候干旱,造林立地条件差,加之技术措施单一,导致多年造林成活率、保存率很低,为此,选择具有代表性的地段进行了河西走廊北部风沙区困难立地条件造林试验,结果表明,相同条件下,顶凌造林可提高造林成活率10～20个百分点,截干造林与全苗栽植相比,造林成活率提高10个百分点。因此,在干旱困难立地条件下造林,综合应用抗旱造林技术,不但可提高造林成活率,而且造林效果明显。

| Abstract: | Turba Beach of Ganzhou District in Zhangye City is an important location of northern ecological barrier in the Hexi Corridor.Arid climate,poor site conditions and a single technical measure cause lower survival & preservation rate for years.For this purpose,representative plots were selected to conduct experiments of difficult site conditions in northern wind-drift area of Hexi Corridor.Result shows that:under the same conditions survival rate can be increased by 10%-20% with slush covering;survival rate of planting with truncated stem increase by 10% than that of planting with full stand.Therefore,to plant in arid difficult ground conditions,comprehensively applying drought-resistant afforestation technique can improve the survival rate,its afforestation effect are significant. |
