Abstract
Maize variety Chuandan 99 was used as experimental material,three irrigation methods,namely conventional border irri-gation,shallow buried drip irrigation and drip irrigation under film,were used to compare the effects of different irrigation methods on dry matter absorption and transfer,yield and water and nitrogen utilization efficiency of maize,in order to find a water-saving irri-gation model suitable for maize planting in Dafang County.
