英文摘要	Utilizing ridge-furrow construction combined with plastic film mulching system (RFMS) is an effective strategy for improving crop productivity in semi-arid areas. However, the key mechanisms by which RFMS stimulates the integrated utilization of key production resources (thermal, water and radiation) to affect maize production is not well-defined. In the Loess Plateau of China, three treatments were applied in a two-year field experiment: 1) RFH with RFMS at a high coverage ratio (50 cm mulched ridge:10 cm unmulched furrow); 2) RFL with RFMS at a low coverage ratio (60 cm mulched ridge:60 cm unmulched furrow); and 3) FP as the control without mulching. RFMS significantly improved soil hydrothermal conditions, which enhanced photosynthesis and promoted canopy growth to intercept more radiation. With an increase of soil thermal time (TTsoil) by 199.1-415.1 degrees C d compared with FP, the thermal effect of RFMS improved maize crop phenology by shortening the duration of vegetative stage to prolonging reproductive stage by 1-3 days, thereby prioritizing the allocation of the captured radiation, thermal and water to reproductive growth. These alterations significantly increased maize grain yield by 38.0-59.6%, and enhanced the efficient use of resources by 13.7-21.9% in thermal, 34.6-59.8% in water and 30.0-50.0% in radiation, which enhanced when increasing coverage (RFH vs. RFL). Overall, these alterations of RFMS on hydrothermal, as an adaptive strategy, can positively mark the capture and allocation of resources and the conversion of resources into biological materials (especially grains) in semi-arid areas like the Loess Plateau.
