摘　　要：为研究不同灌溉方式对玉米生长及土壤质量的影响,2023年在河南新郑市,设置沟灌、地表滴灌和地下滴灌3个处理,研究不同灌溉方式对玉米干物质积累、产量以及土壤理化特性的影响。结果表明,不同灌溉方式处理的玉米生长和土壤理化性质存在明显差异,其中地下滴灌处理的玉米干物质积累量、产量和土壤速效磷、速效钾、毛管孔隙度显著高于其他处理,产量比沟灌和地表灌溉高出14.33%和9.98%,土壤容重显著下降。因此,地下滴灌是较适合当地的灌溉方式。In order to study the effects of different irrigation methods on corn growth and soil quality,In 2023,three treatments of furrow irrigation,surface drip irrigation and subsurface drip irrigation were set up in Xinzheng City,aimed to investigate the impacts of these irrigation methods on the accumulation of dry matter in corn,yield and soil physical and chemical properties.The results showed that there were significant differences in corn growth and soil physical and chemical properties among different irrigation treatments.Corn under subsurface drip irrigation had notably higher accumulation of dry matter,yield and levels of available phosphorus,available potassium and capillary porosity compared to the other treatments.The yield was higher than that of furrow irrigation and surface irrigation by 14.33% and 9.98%,and the soil bulk density decreased significantly.Therefore,subsurface drip irrigation is more suitable for local irrigation.
