Summary:［Objective］ We conducted a field experiment to investigate the effects of intercropping green manure crops and their combination with ground fabric mulching on soil moisture, fertility, and apple yield. ［Methods］ The main treatments included intercropping ryegrass (NGR), oilseed rape (NGO), and alfalfa (NGA), the sub-treatments included combining these intercropping modes with mulching ground fabric under apple trees (GR/GO/GA), and the control treatment was traditional clean tillage (CK). Additionally, 15N labeled microplots were set up within the main and control treatments. The responses of soil moisture, nutrients, and fruit yield were explored under the apple-green manure intercropping system. ［Results］ All treatments reduced soil water content (SWC) compared to CK, among which the decreasing range of GR (1.7%) was the smallest. Soil water difference ratio (SWDR) in the main treatments were all negative, among which NGR and NGA had the smallest (0.5%) and largest (4.7%) absolute value, respectively. All
