Abstract
Through field experiment,we compared the influences of different combinations of irrigation and fertilization on the tiller,root growth,the leaf area index,yield,and water productivity of single-cropping rice.The aim of this study was to explore the mechanism of water conservation and yield increasing of single-cropping rice.The results show that the tiller of rice under water-saving irrigation(thin layer and dry irrigation or alternate dry and wetting) is better than conventional irrigation,and the tiller of three-split fertilization is better than that of two-split;the root length and total root hair are greater than conventional irrigation;the influence of different irrigation on the leaf area index is not significant,but the yield of water-saving irrigation and three-split fertilization is greater than conventional treatment,with yield increment of 10~30 kg/mu.Besides,water-saving irrigation can improve water productivity significantly,and save 10%~30% of irrigation water during growing stages.
