Abstract

Abstract: We examined root fractal parameters, root length, root quantity, root mass, root-shoot ratio of 3-year-old seabuckthorn in the Pisha sandstone area of Inner Mongolia, using the fractal theory and statistical method. The results showed that soil moisture had the most significant effect on the root architecture, followed by slope. Slope position had the least effect on the root architecture. The seabuckthorn in the Pisha sandstone area was suitable for planting on slope bottom or mid-slope with a soil moisture of about 8%. Mid-slope with a slope of 30°-35° was recommended. The root-shoot ratio of seabuckthorn decreased with increasing soil moisture. It increased at first and then decreased with increasing slope and slope position. Seabuckthorn with the characters of developed root and high root-shoot ratio in arid and barren midslope meets the basic requirements of tree species for soil-fixing and slope-protection.
