英文摘要	The purpose of this study was to improve the water and fertilizer use efficiency of rice in semi-arid area. A field experiment was conducted to study the water-saving and fertilizer-reducing effects of clinoptilolite (Z) in water-saving irrigated paddy fields and to clarify the relationships between sink-source traits and rice yield. Z coupled with alternate wetting and drying (AWD) irrigation showed increased water saving by 4.8-11.4%, and the Z&AWD (NAZ) and Z&AWD with 25% less phosphorus (P) treatments (LPAZ) significantly increased water productivity by 15.5% on average. The stage in which Z had the most pronounced effect under AWD on dry matter (DM) accumulation was between 30 and 60 days, while under continuously flooded (CF) irrigation, Z had the greatest effect after 60 days, indicating that Z coupled with AWD irrigation was conducive to the DM increase at the vegetative growth stage. LPAZ and NAZ showed lower average nitrogen (N) acccumlation rate and higher grain-filling duration. The principal component analysis indicated the larger N accumulation in early-stage and longer N accumulation duration were conducive to higher grain-filling rate and rice grain yield. To maximize the yield-increasing effect and optimize grain-filling parameters, effective nitrogen fertilizer managements should guarantee the N accumulation duration and stability, and improve the nitrogen accumulation amount in early stage. Clinoptilolite and AWD with 25% less P treatments led to greater, longer, and more stable N accumulation, which saved irrigation water, phosphorus fertilizer, and improved production efficiency.
