[Effect of High-volume Straw Returning and Applying on Bacterial Community and Fertility of Desertification Soil].

This study was conducted to explore the fertilization potential of the high-volume straw returning mode in cooperation with and other functional flora on desertification soil and to analyze the changing characteristics of soil carbon, nitrogen, and phosphorus components and functional activities of flora, so as to provide a basis for efficiently improving desertification soil fertility. A randomized block experiment was conducted, setting straw not returning to field (CK) and high-volume straw returning of 6.00 kg·m (ST1), 12.
