英文摘要	Water shortages continue to threaten the productivity of rain-fed maize, so there is an urgent need to develop efficient water-saving management methods under different farming modes. This study explores the potential effects of various farming modes and fertilizer management practices on chlorophyll fluorescence, resource utilization efficiency, and rain-fed maize productivity. A field trial under two farming modes were conducted during 2019-2020: P: plastic film mulching on ridges; F: traditional flat planting; There were five fertilizer management practices under each cropping mode, i.e., 0: no nitrogen fertilizer; FN: the common nitrogen fertilizer rate for farmers is 290 kg ha(-1); ON: optimal nitrogen application rate 230 kg ha(-1); (ON75%+DCD): optimal nitrogen fertilizer rate reduction by 25% + dicyandiamide; (ON75%+NC): optimal nitrogen rate reduction by 25% + nano-carbon. The results showed that compared with other treatments, the PON75%+DCD treatment significantly increased soil water storage which was due to the decrease in evapotranspiration (ET) rate. We found that at the treatment of PON75%+DCD or PON75%+NC, the net photosynthetic (P-n), photosynthetic performance index PSII (Fv/FmMODIFIER LETTER PRIME), electron transfer rate (ETR), maximum quantum efficiency PSII (Fv/Fm), PSII energy conversion potential (Fv/Fo) and effective quantum yield of PSII (phi(psII)) were recorded maximum at the jointing, flowering, and grain-filling stages. The treatment of PON75%+DCD or PON75%+NC significantly improved soil water storage, flag leaf chlorophyll ab content (36.4%), biomass yield (22.7%), grain yield (32.1%), rainfall use efficiency (47.5%), water use efficiency (42.6%), and agronomic efficiency (80.0%), while significantly reducing the evapotranspiration rate (13.9%), compared with F-FN farming mode. The PON75%+DCD treatment improved the photosynthetic characteristics, chlorophyll fluorescence, nutrient utilization, and maize productivity. Therefore, we find out that PON75%+DCD farming mode is the best fertilizer and water-saving management practice for maize production in semi-arid regions.
