| 摘 要： | 2008-2010年在渭北旱塬区,以沟不覆盖为对照(CK),研究垄上覆地膜沟内分别覆普通地膜(PP)、生物降解膜(PB)、玉米秸秆(PS)和液体地膜(PL)4种沟垄全覆盖种植模式对土壤水温、玉米生长、产量及水分利用效率的影响.结果表明,在玉米生长前期,PP、PB和PS处理可明显提高0-200 cm土壤蓄水量；生育中期,PS处理蓄水保墒效果最为显著；生育后期,各沟垄全覆盖处理与对照的土壤蓄水量无显著差异；整个生育期PL处理与CK的土壤蓄水量差异不显著.PP和PB处理3a玉米生育期5-25 cm平均土壤温度分别较CK增高1.6℃和1.3℃,PS处理降低1.9℃,而PL处理与CK无显著差异.PP和PB的增温保水效应使玉米株高、叶面积及地上生物量均高于CK;PS处理的降温效应促进玉米中后期生长,其株高、叶面积及地上生物量均高于CK;PL处理对玉米各生长指标影响不显著.与CK相比,PP、PB和PS处理3a平均的籽粒产量分别提高13.0％、13.8％和15.0％,水分利用效率分别提高9.8％、10.2％和11.6％.可见,垄覆地膜沟覆地膜、生物降解膜或秸秆的沟垄全覆盖种植可明显改善土壤的水温状况,促进玉米生长,从而显著提高作物产量和水分利用效率,对渭北旱塬区春玉米丰产栽培具有重要指导意义.
