摘要: 研究不同灌水量对大兴安岭东麓东北春玉米产量和水分利用效率的影响,旨在为提高东北春玉米水分利用效率提供技术支持。本试验共设置5种灌水处理,并对自然降水及灌水量等指标进行监测记录,以测定不同处理下的土壤含水量和土壤容重,同时结合产量进行相关计算,测得玉米水分利用效率,最后测定农艺性状并进行相关分析。结果表明:在大兴安岭东麓玉米田,灌水量为1 500 m3/hm2时,产量最高,为14.55 t/hm2,水分利用效率最高,为6.7 kg/m3。大兴安岭东麓地区玉米田灌水量为1 500 m3/hm2时,较有利于提高东北春玉米的产量和水分利用效率。

关键词: 东北春玉米, 灌水量, 产量, 水分利用效率

Abstract: The effects of different irrigation amounts on the yield and water use efficiency of Northeast spring maize were studied in order to provide technical support for the improvement of water use efficiency of Northeast spring maize in the eastern foot of the Greater Khingan Mountains.In this experiment,5 irrigation treatments were set up.Natural precipitation and irrigation amounts as well as other indicators were monitored and recorded.The soil moisture content and soil bulk density of different treatments were measured,and related calculation was carried out combined with yield to obtain the water use efficiency of maize,and in the meantime,agronomic characteristics were determined and related analysis was carried out.The results showed that when the irrigation volume was 1 500 m3/hm2,the yield was 14.55 t/hm2 and the water use efficiency was up to 6.7 kg/m3 .When the irrigation volume of cornfield in the eastern foot of Greater Khingan Mountains is 1 500 m3/hm2,it is beneficial to improve the yield and water use efficiency of spring maize.

Key words: Northeast spring maize, Irrigation water, Yield, Water use efficiency
