Abstract

Abstract:

To solve the bottleneck problems of poor development and serious degradation of Hedysarum scoparium artificial shrubbery in the western Ordos region of Inner Mongolia, and to screen the optimal stubble height for promoting the growth of Hedysarum scoparium, the artificial shrubbery of Hedysarum scoparium in Etuoke Banner of western Ordos was taken as the research object. The 0 cm (H₁), 10 cm (H₂) and 20 cm (H₃) stubble treatments were carried out, and the non-stubble Hedysarum scoparium was used as the control (CK). The effects of different stubble treatments on the fine root chemical properties and soil nutrients of Hedysarum scoparium were analyzed. The results showed that: (1) the chemical traits of fine roots of Hedysarum scoparium showed that the 10 cm flat stubble treatment was superior to other flat stubble treatments, and the average values of fine root carbon content, fine root nitrogen content and fine root carbon-nitrogen ratio in the second year of flat stubble were 346.72, 4.91 and 70.57 g/kg, respectively. (2) Under different flat stubble treatments, the soil nutrients under Hedysarum scoparium forest were also different. The 10 cm flat stubble treatment was the best, and the soil organic matter, soil available nitrogen, soil available phosphorus and soil available potassium were 6.61, 6.11, 2.48 and 28.43g/kg, respectively. The soil nutrients gradually decreased with the increase of soil depth, and the 0-10 cm surface soil layer was the best. (3) The comprehensive analysis of membership function of each index in the second year of flat stubble showed that 10 cm flat stubble treatment was the best. The paper provided a theoretical basis and technical support for the scientific guidance of ecological protection and restoration actions in western Ordos and even similar desert environments.
