采用田间试验方法，研究了不同覆盖种植方式与平衡施肥对旱地春玉米产量及其水分利用效率的影响。结果表明，三种覆盖种植方式中，全膜双垄沟播种植方式有利于玉米碳水化合物的合成，增加玉米干物质积累量，N、P、K平衡施肥干物质积累量增加效果明显；与全膜双垄沟播相比，半膜覆盖和裸地种植玉米籽粒产量分别减产8．5％～17．6％和61．1％～95．3％，水分利用效率分别降低3．5％～15．1％和52．8％～60．2％；N、P2O5和K2O的用量分别为225、120、60 kg·hm-2时，F1 N1处理玉米籽粒产量和水分利用效率最高。研究表明，在玉米全膜双垄沟播栽培技术条件下，平衡施肥可显著提高玉米籽粒产量和水分利用效率。

Field trials were conducted to study the effect of mulching cultivation and balance fertilization on yield and water use efficiency of corn in the dryland .The results showed that film mulched double-furrow sowing had a favor-able effect on carbohydrate synthesis and thereby the dry matter accumulation of corn ,with the balance pattern of fertil-ization having the largest effect .Compared with all-film double-furrow sowing cultivation ,maize yields of semi-film cov-ering cultivation and exposed land cultivation was reduced by 8 .5% ~17 .6% and 61 .1% ~95 .3% ,and water use ef-ficiency of which was reduced respectively by 3 .5% ~15 .1% and 52 .8% ~60 .2% ,respectively .The application rate of N 225 kg·hm-2 ,P2O5 120 kg·hm-2 ,and K2O 60 kg·hm-2 resulted in the highest maize yield and water use effi-ciency ,suggesting the feasibility of balance fertilization in plastic-film mulched double-furrow sowing pattern .
