Water shortage continues to threaten the productivity of rapeseed in China dry-land planting system china. There is an urgent need build up efficient water saving management practices. Therefore, field experiment was conducted by using a randomized complete black design with three replications under two cultivation practices: RF: ridge-furrow rainwater collection system, and CP: conventional flat planting; four different mulching materials, such as plastic film (PM); biodegradable (BM); straw mulch (SM) no (NM) were used this study. We found that practices have considerable effect on improvement soil storage. Under RF-PM RF-BM treatments can considerably improve photosynthesis (Pn, 54.1%), ETR (50.9%), ΦpsII (38.4%), maximum quantum efficiency (Fv/Fm, 8.9%), Fv/Fo (25.7%) Fv/Fm′ (26.1%), at bolting, flowering seed filling stage. These enhancements attributed significant increase storage, total chlorophyll ab (59.4%), stability index, well decrease evapotranspiration (ET, 3.9%), all which improved use (WUE, 28.0%), cuticular wax composition, grain yield (25.2%) economic return (10459 Yuan ha−1) rapeseed. results showed RF practice PM materials best water-saving photosynthesis, fluorescence, WUE, agricultural systems.
