Abstract:

To study the effects of different stumping treatments on the ecological and physiological characteristics and soil moisture content of the underground part of Salix psammophila in the western Ordos area of Inner Mongolia, the total root length, total volume, total surface area, root activity, proline, soluble sugar and soil moisture content of Salix psammophila under different stumping treatments were studied, and the optimal stubble mode was selected by using the comprehensive analysis method of membership function. The results showed that the 0 cm stubble treatment exhibited the best performance in terms of fine root physiological and ecological characteristics, as well as soil moisture content. The mean values in vertical (horizontal) direction were: fine root vitality 53.70 mg/(g·h), proline 20.26 μg/g, soluble sugar 59.89 mg/g, total root length 443.52 cm (407.49 cm), total volume 1.11 cm3 (0.86 cm3), and total surface area 115.25 cm2 (108.98 cm2); the soil moisture content was 4.95% on average. This study provides important theoretical and scientific bases for vegetation restoration and ecological environment construction in similar desert environments.
