摘要： To investigate the effect of different depths of film-bottomed tillage (DFBT) on soil physical and chemical characteristics, agronomic traits, and yield of dryland spring wheat in arid regions of China. A two-year field experiment was conducted to assess soil and plant responses to varying depths of film-bottomed tillage for spring wheat cultivation. Measurements included soil texture, bulk density, porosity, pH, nutrient content, microbial biomass, and soil NO3--N and NH4+-N levels. Plant parameters such as root-to-shoot ratio (R/S) during early growth stages and grain yield were also evaluated. The soil texture became finer with increasing DFBT depth. Bulk density decreased by 0.02 to 0.08 g cm(-3), while porosity increased by 0.71-5.38%. Mean soil pH decreased from 8.79 to 8.42. Soil nutrients, microbial biomass, and soil NO3--N and NH4+-N contents increased significantly. The R/S ratio of spring wheat under film-bottomed treatments was significantly lower during the early growth stage compared to the control. Grain yield increased significantly under FBT. Film-bottomed tillage, especially at optimized depths, enhances soil physical and chemical properties, improves nutrient availability, and increases the grain yield of dryland spring wheat. FBT provides a viable solution to enhance food security in arid areas with similar conditions.
