摘　　要：玉米是辽西北地区主要种植作物,为探讨不同微喷控制灌溉程度对辽西北地区玉米生长及需水规律影响,本文采用单因素试验方法,以雨养处理(YY)为对照,在2019年和2020年连续开展了轻度控制灌溉(QK)和重度控制灌溉(ZK)对玉米相关影响的研究。研究表明:与YY相比,QK和ZK均有利于玉米生长,其中QK处理效果最佳。QK灌水量和耗水量最大,产量和水分利用效率也最大,当地玉米生产中节水增效最为明显,适宜在辽西北地区推广。Maize is one of the main crops in northwest Liaoning.In order to explore the effects of different degrees of micro-spray controlled irrigation on maize growth and water demand in northwest Liaoning,a single factor experiment was conducted with rain-fed treatment(YY)as control.The effects of mild controlled irrigation(QK)and heavy controlled irrigation(ZK)on maize were studied continuously in 2019 and 2020.The results showed that compared with YY,both QK and ZK were beneficial to the growth of maize,and the effect of QK was the best.QK has the largest irrigation and water consumption,the highest yield and water use efficiency,and the most obvious water saving and efficiency in local maize production,so it is suitable to be popularized in the northwest of Liaoning Province.
