中文摘要	为进一步明确我国西北地区全膜双垄沟播玉米栽培技术的增产机理,为干旱半干旱地区玉米高产栽培提供理论与技术支持,20082009年采用田间试验方法,研究了7种不同栽培方式对陇东地区旱地玉米根系时空分布、产量及水分利用效率的影响。结果表明:不同栽培方式下玉米根系长度和根干重均随生育期的推进逐渐增加,且随土层的加深呈逐渐下降趋势。其中,全膜双垄沟播等行距种植模式0~150 cm土层玉米根系长度显著大于半膜双垄沟播、常规地膜覆盖和露地种植模式(P<0.05);120~150 cm土层根长百分比表现为全膜双垄沟播撮苗种植模式最大,全膜双垄沟播等行距种植模式次之,露地种植模式最小;根干重主要集中在0~30 cm土层,且垄沟>垄中,全膜双垄沟播>常规覆膜>半膜双垄沟播,等行距种植>撮苗种植;与半膜双垄沟播、常规地膜覆盖和露地种植模式相比,全膜双垄沟播等行距种植玉米籽粒产量分别提高17.72%、22.01%和47.00%,水分利用效率分别提高6.41%、18.54%和43.57%,是陇东地区旱作玉米的最佳栽培方式。
英文摘要	Field experiments were conducted in 2008~2009 to study the effects of 7 cultivation patterns on the distributions of maize roots,yield and water use efficiency(WUE).The objective of the study was to further make clear the enhancing mechanisms of maize production under full film mulching and double furrow system in northwest China and to lay the theoretical and techno-logical basis of cultivation techniques for high-yield maize in arid/semi-arid areas.The results showed that while root length and dry weight gradually increased with growth duration,and they gradually declined with soil depth under different cultivation patterns.Root length in the 0~150 cm soil layer under even row-spacing sowing in furrow with whole film mulching was significantly longer than those under sowing in furrow with semi-film mulching and conventional cultivation with or without film mulching.Pinch sow-ing in furrow with whole film mulching had the highest percent root length distribution in the 120~150 cm soil depth,followed by even row-spacing sowing in furrow with whole film mulching.Conventional cultivation without film mulching had the least percent root length distribution in the 120~150 cm soil layer.Most of the root dry weight was concentrated in the 0~30 cm soil layer,and was higher in furrows than in ridges.Root dry weight order was as follows: sowing in furrow with whole film mulching > conventional cultivation with film mulching > sowing in furrow with semi-film mulching,even row-spacing sowing > pinch sowing.The results further showed that even row-spacing sowing in furrow with whole film mulching improved grain yield by 17.72%,22.01% and 47.00%,and WUE by 6.41%,18.54% and 43.57%,respectively,compared with sowing in furrow with semi-film mulching,conven-tional cultivation with film mulching and conventional cultivation without film mulching.Even row-spacing sowing in furrow with whole film mulching was the optimum maize cultivation method in Longdong area of northwest China.
