摘　　要：为了探讨辽西北地区适宜的玉米滴灌方式,采用田间小区试验,研究了覆膜与非覆膜2种滴灌条件下土壤含水率、土壤温度、玉米生长性状、灌溉水利用效率及经济效益变化规律。结果表明,覆膜滴灌可有效地保持土壤计划湿润层内的土壤水分,减少灌溉水量,提高土壤温度,加速生育进程,增加每穗粒数和百粒质量进而提高玉米产量,显著提高了灌溉水利用效率,增加了经济效益。因此,覆膜滴灌更适合在辽西北推广。A field plot experiment was conducted to evaluate soil moisture,soil temperature,maize growth traits,irrigation water efficiency and economic benefits under mulching and non-mulching drip irrigations to explore suitable drip irrigation mode for maize in Northwest Liaoning.The results showed that mulch drip irrigation could effectively maintain soil moisture in soil wetting layer,reduce the amount of irrigation water,increase the soil temperature,accelerate growth and development,increase the per ear grain number and 100 grain weight as well as the yield of maize,and therefore improve irrigation water use efficiency,enhance economic benefits.Therefore,mulching drip irrigation is suitable for wide application in northwest Liaoning.
