摘要： 循环曝气地下灌溉可以改善灌溉造成的根区缺氧状况，为作物生产潜力的发挥提供了可能。为阐明循环曝气地下滴灌对不同土壤类型的适用性，选择河南省郑州潮土、洛阳红粘土、南阳黄褐土、商丘两合土4种典型土壤，以冬小麦为指示作物，利用盆栽试验研究冬小麦的耗水特性、作物生理指标及产量对循环曝气地下滴灌的响应。结果表明，4种土壤曝气处理耗水量均高于普通地下滴灌处理（对照处理）。与对照相比，郑州潮土、商丘两合土曝气处理气孔阻力下降了66.72%和61.47%，达到显著性差性水平(P≤0.05)，洛阳红粘土和南阳黄褐土气孔阻力差异不显著(P>0.05)。洛阳红粘土曝气处理产量较对照处理增加了12.61%(P≤0.05)，千粒重增加了12.23%(P≤0.05)，而南阳黄褐土、商丘两合土和郑州潮土曝气处理与对照差异不显著(P>0.05)。综合以上考虑，循环曝气地下滴灌技术在洛阳红粘土上对冬小麦有显著性的改善效果。

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.
