Abstract: Aerated subsurface irrigation provides a source of oxygen in a root environment that suffers from temporal hypoxia, and unlocks yield potentials of crops. In order to study the applicability of aerated irrigation in winter wheat under different soil condition of alluvial soil in Zhengzhou City (ZZ), red clay in Luoyang City (LY), yellow cinnamon soil in Nanyang City (NY) and fluvo-aquic soil in Shangqiu City (SQ), the effects of aerated irrigation on water consumption characteristics, physical signs, yield and the quality of winter wheat were investigated by pot experiment. Compared to the control treatments, the water consumption of the aerated group in ZZ, LY, NY and SQ treatments were increased. The stomatal resistances of ZZ and SQ treatments were decreased by 66.72% and 61.47% respectively compared with control treatments. There was no significant difference in NY and LY treatment. The yield and 1000-grain weight in aerated group of LY treatment was increased by 12.61% and 12.23%. There was no significant difference in ZZ, NY, and SQ treatment. Our data suggested that cycle aerated subsurface irrigation could improve the crop yield and crop quality of winter wheat in the LY treatment.
