中文摘要	通过田间试验对半干旱区不同栽培方式下玉米土壤水分分布及水分利用效率的研究,探明了全膜双垄沟播玉米农田高效用水的机制.结果表明:全膜双垄沟播栽培不同位置大垄,垄沟,小垄土壤平均含水量在060 cm土层内差异显著(P<0.05),且垄沟含水量最高,其次为大垄,小垄最低;播种期060 cm土层平均体积含水量全膜双垄沟播与露地平作差异显著(P<0.05),升高14.19%,且拔节期以前全膜双垄沟播种植土壤贮水量最高,表明全膜双垄沟播栽培有利于玉米的出苗及前期的生长;全膜双垄沟播栽培较半膜平作增产26.76%,水分利用效率较半膜平作提高14.83%
英文摘要	Soil water distribution and water use efficiency of maize in different planting patterns in semi-arid area was studied using field experiments to clarrify high water use efficiency mechanism of maize planting in furrows of completely mulched alternating narrow and wide ridges systems in rainfed area. The results showed that the average soil water content in various measureing positions was significantly different at 0.05 level;The water content in furrows is the highest followed by the water content on big ridges, smaller ridges were the dryest in the field;The average soil water content in 0~60 cm depth of completely mulched alternating narrow and wide ridges with furrow planting(T4) was 14.19% higher than flat-planting without mulching at planting time;Soil water storage in 0~60 cm reaches the highest in jointing stage, which indicates T4 is beneficial for emergence and early growth of maize;Compared with half-mulching and flat-planting, yield and WUE of completely mulched alternating narrow and wide ridges with furrow planting was increased by 26.76% and 14.83% respectively
