中文摘要	【目的】解决干旱灌区大面积实行传统覆膜对土壤环境造成污染和灌量过大对水资源造成浪费的问题.【方法】本研究于2016年在甘肃省河西走廊开展田间试验,研究了一膜两年用(M_1)、传统耕作覆膜(M_2)两种覆膜方式与低(I_1:450mm)、中(I_2:495mm)和高(I_3:540mm)3个灌水量组合对玉米间作豌豆水分利用效率的影响,以期为该区地膜减投、节水间作种植模式提供科学依据.【结果】覆膜方式对玉米间作豌豆的总耗水量影响不显著,但增大灌溉量作物总耗水量显著增大.覆膜方式和灌水量均对棵间蒸发量影响显著,且互作效应显著.M_1在低、中、高灌水量下棵间蒸发量较M_2减小了22.8%,20.6%,18.1%,棵间蒸发量随灌水量的增大显著增大.覆膜方式和灌水量均对蒸散比(E/ET)影响显著,且交互作用对E/ET有显著影响.与M_2相比,M_1显著降低了低、中、高灌水量下E/ET,降低幅度为22.0%,16.7%,15.5%,随着灌水量的增加E/ET增大.覆膜方式对籽粒产量、生物产量影响不显著,灌水量对其影响显著.M_1I_2获得较高的籽粒产量和生物产量,分别达14 580.1kg/hm~2和31 227.6kg/hm~2,一膜覆两年中灌水量下WUE较高,达到18.8kg/(hm~2·mm).【结论】一膜两年用中灌水量可作为干旱灌区减少污染,提高资源利用效率的种植模式之一.
英文摘要	【Objective】To solve the problems of soil pollution due to conventional mulching widely used and the waste of water resource caused by over-irrigation in arid area,a field experiment was conducted at Hexi Corridor,Gansu Province in 2016.【Method】The experiment designed two tillage treatments:plastic film mulching for 2 years(M_1)and conventional tillage(M_2)and three irrigation levels:the low level(I_1:450mm),medium level(I_2:495mm)and high level(I_3:540mm)to provide theoretical basis for reducing plastic film mulching input and water-saving strategies by assessing the water use efficiency in maize-pea intercropping system.【Result】The results showed that the treatment of plastic film mulching had no significant effect on total water consumption,but total water consumption increased significantly corresponding to the increasing irrigation level.Both plastic film mulching patterns and irrigation levels had significant effects on the soil evaporation,and the interaction effect between them was also significant.The treatment M_1 significantly decreased the soil evaporation under low,medium and high irrigation level by 22.8%,20.6% and 18.1% than that of M_2,respectively.The soil evaporation increased with the increase of irrigation level.Plastic film mulching patterns and irrigation levels had significant effect on E/ET,and the interaction effect on E/ET was also significant.M_1 significantly decreased E/ETby 22.0%,16.7% and 15.5% compared to M_2.The E/ETincreased with increasing irrigation level.Plastic film mulching patterns had no significant effect on grain yield and biological yield,but the irrigation levels significantly affected them.The treatment M_1I_2 obtained higher grain yield of 14 580.1kg/hm~2 and biological yield of 31 227.6kg/hm~2.Plastic film mulching for 2 years obtained higher WUE of 18.8kg/(hm~2·mm)under medium irrigation level.【Conclusion】Plastic film mulching for 2 years can be used as an optimized cropping pattern for reducing soil pollution and improving resource use efficiency in arid irrigation area.
