节水模式对玉米产量的影响

The Impact of Water-saving Mode on the Yield of Maize

以川单99玉米品种为试验材料,设置常规畦灌、浅埋滴灌、膜下滴灌3种灌溉方式,比较不同灌溉方式对玉米干物质吸收及转运、产量、水氮利用效率的影响,以期找到适宜大方县玉米种植的节水灌溉模式。

Maize variety Chuandan 99 was used as experimental material,three irrigation methods,namely conventional border irrigation,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 irrigation model suitable for maize planting in Dafang County.
