英文摘要	PurposeAlfalfa (Medicago sativa L.) production is adversely impacted by surface runoff and drought stress. This is particularly true for alfalfa planted in semiarid areas. Therefore, the development of erosion-tolerant management practice is crucial.MethodsA study was carried out in a completely randomized design, with 4 treatments (3 straw biochar application rates + flat planting (FP) as control), and 3 straw biochar application rates of 0 x 10(4) (no biochar (NB)), 3 x 10(4) (single straw biochar-soil crust (SSB)) and 6 x 10(4) kg hm(-2) (double straw biochar -soil crust (DSB)), respectively.ResultsMean runoff efficiency in SSB was 16.58% compared to no-biochar treatment (20.14%), and in DSB was 14.57%. From 2017 to 2020, NB had the highest R-2 value for the variation between runoff and rainfall and DSB had the lowest R-2 value. In comparison to FP treatment, application of biochar to SSB significantly (p < 0.05) reduced runoff and increased soil water storage. The difference in soil water storage between pre-sowing and post-harvesting during alfalfa growth season increased on average by 15.69% with NB practice compared to FP, and by 11.79% and 7.58% with SSB and DSB practices, respectively. The mean weight diameter (MWD) in SSB treatment was higher than that in DSB treatment, although soil nutrients were increased in the following order: DSB > SSB > NB > FP. After post-harvest, average yields in NB, SSB, and DSB treatments were higher than those in FP treatment by 8.16%, 25.71%, and 18.31% respectively. With a mean yield of 8607 kg ha(-1), SSB significantly increased alfalfa yield across all years.ConclusionEvidence from the four-year experiment suggested that biochar-soil crust made from a single straw significantly reduced surface runoff, increasing soil water storage, soil aggregate stability, soil nutrients, and alfalfa fodder yield. Based on our research, we advise using single straw biochar-soil crust to boost alfalfa fodder production in semi-arid regions.
