| 摘 要： | 为高效利用辽西半干旱区有限农业水资源,在2006～2007年进行了两年的田间有限补灌制度研究。结果表明,有限补灌对籽粒产量和农田水分利用效率有明显的影响。通过分析不同处理的产量、灌溉效率和水分利用效率,最终优选确定了辽西半干旱区有限补灌制度,为该区春玉米大田补灌生产提供技术支撑。

| Abstract: | In order to take advantage of the water resource in semiarid region of west Liaoning, the field experiment of limited supplementary irrigation scheduling was conducted during 2006 -2007. The results showed that seed yield and water use efficiency were obviously effected by measure of limited supplementary irrigation. This study established the limited supplementary irrigation scheduling for spring maize in semiarid region of west Liaoning, which was based on the analyse on yield effect, irrigation efficiency and water use efficiency. The limited supplementary irrigation scheduling can provide the technical support for the largescale field of supplementary irrigation on spring maize. |
