Abstract:Krascheninnikovia ceratoides not only serves as a good forage grass, but also creates a significant ecological barrier, which can maintain the stability of the desert-steppe ecosystem by effectively inhibiting soil erosion. Moving leads to compensatory plant growth and stimulates the secretion of carbohydrates from plant roots. Once the aboveground biomass of plant is damaged, its underground soil properties may change. Rhizosphere soil is of great importance because it serves as a microenvironment where plant, soil, and microorganisms can carry out nutrient cycling, the exchange of energy and the passing of information. Therefore, rhizosphere soil is strongly affected by plant roots and the activity of microorganisms. There currently is no research regarding moving on the rhizosphere soil properties of K. ceratoides. Therefore, a study of the impacts of moving on the rhizosphere soil properties of K. ceratoides could reveal the influence moving has on its underground biomass. Furthermore, it also can serve as a basic reference for putting K. ceratoides resources to rational use. In order to analyze the impacts of different moving frequencies on rhizosphere soil properties of K. ceratoides in the steppe desert, the soil physical and chemical properties, as well as the soil microorganisms and soil enzymatic activity, were investigated after different moving treatments (e.g., moving once a year, moving each year at a year interval) during the dormant period. Our results indicated that moving once a year and moving each year at a year interval significantly increased the rhizosphere soil moisture of K. ceratoides (P<0.05). Moving each year at a year interval resulted in significantly greater total soil C content, but lower soil organic matter content relative to the contrast (P < 0.05). However, neither the soil pH, nor the soil total N content was affected relative to the moving treatment. Moving had no significant influence on a total plate count of soil microorganisms, but significantly altered the composition of soil microorganisms including bacteria, fungi and actinomyces. The number of fungi significantly increased after moving once a year, while moving each year at a year interval significantly increased the number of actinomyces (P<0.05). Actinomyces were greater in number in the rhizosphere soil of K. ceratoides, representing some degree of soil impoverishment. Moving had a significant impact on soil hydrogen peroxidase and neutral phosphatase activity, but no significant influence was detected for soil polyphenol oxidase, urease, invertase, and alkaline phosphatase. Moving significantly increased the activity of soil hydrogen peroxidase, but reduced the activity of soil neutral phosphatase (P<0.05). In summary, moving each year at a year interval was more beneficial for rhizosphere soil nutrient supply and for the activity of soil decomposers. Furthermore, the soil's physical and chemical properties had little effect on soil microorganisms and soil enzymatic activity. The effects of mowing on the rhizosphere soil properties of K. ceratoides were not strong, perhaps because the time of moving on subshrubs was not long enough to provide a significant correlation of each measurement indicator.
