- 摘要:
- 以柠条锦鸡儿（Caragana korshinskii）细根为研究对象，在赤峰市敖汉旗黄花甸子流域研究区，运用EPSON根系扫描仪和Winrhizo根系系统对柠条锦鸡儿细根特征进行分析，研究了柠条锦鸡儿细根根长密度随不同土层深度变化规律以及其与土壤养分和含水率的关系。结果表明：柠条锦鸡儿细根根长密度随土层深度的加深，总体呈递减的趋势，细根根长密度于0~20 cm层达到最大值；通过细根特征与土壤养分和含水率分析，发现柠条细根根长密度与土壤养分相关性最大，与含水率相关性不明显。该研究旨在为北方农牧交错带植被恢复提供参考依据。
- Abstract:
- Huanghuadianzi watershed was chosen as the researched area and fine roots of Caragana korshinskii as the study object,by adopting the combination of field experiment and indoor experiment methods mainly using Epson scan and Winrhizo system to analyze how the root length density of fine roots changed in different soil layers,and analyzed the correlation between root length density and soil nutrient.The results showed that the root length density decreasesd while the soil depth increased.Root length density reached the maximum in 0-20 cm layer.It was found that root length density had a significant relationship with soil nutrients than water content.It aimed at providing theoretical basis for vegetation restoration in the north of China.
