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.
