摘要
油松是我省荒山造林的主要树种,在全省各地水土保持工程建设中被广泛应用。为了评价油松幼苗在高海拔地区的适应性,采用小区栽植及原位观测的办法测定2016-2018年度树木生长季初期、中期、末期的树高和地径。结果表明,油松完成缓苗后,随着时间的推移,平均苗高、地径均呈现快速增加的变化趋势,不同样地间苗高、地径的生长量存在显著差异,基本上表现为下坡>上坡>中坡;在当地的自然条件下进行造林设计时应优先在阴坡的下部栽植油松,其次上部。
Pinus tabulaeformis is the main tree species for afforestation of barren mountains in our province.It is widely used in the soil and water conservation projects.In this paper,the seedlings were planted at different slope positions in the high altitude area.The growth adaptability of seedlings in the area was evaluatedby continuously measuring the growth changes of height and ground diameter.The result can provided scientific basis for the selection of tree species in afforestation projects in relevant areas.
