不同立地环境对刺叶高山栎幼苗生长的影响

Effects of Different Site Environments on the Growth of Quercus spinosa Seedlings

为了解不同立地环境对刺叶高山栎幼苗生长的影响,以1年生刺叶高山栎苗木为材料,设置不同立地条件,通过1年的跟踪观察,测定了刺叶高山栎苗木生长的各项指标及生物量,并运用方差分析等方法确定刺叶高山栎人工种植最适生长的立地环境。结果表明:刺叶高山栎适合在海拔1600 m、坡度为25°、坡位为中坡、坡向为半阳坡半阴坡、土质类型为棕壤土的区域生长。研究结果可为该地区刺叶高山栎人工造林提供科学依据。

In order to understand the effects of different site environments on the growth of Quercus spinosa seedlings,1-year-old Quercus spinosa seedlings were used as materials,and different site conditions were set up.Through one-year tracking observation,the various indicators and biomass of Quercus spinosa seedlings growth were measured,and variance analysis and other methods were used to determine the most suitable site environment for artificial planting of Quercus spinosa.The results showed that Quercus spinosa was suitable for growing in the area with altitude of 1600 m,slope of 25°,slope position of middle slope,slope aspect of semi-sunny slope and semi-shady slope,and soil type of brown soil.The results provide a scientific basis for artificial afforestation of Quercus spinosa in this area.
