| 摘 要： | 通过2008—2010年两年的大田试验,研究了基施氮、追氮和垄膜沟播种植对晋南雨养区冬小麦生育期0～2m土层土壤水分、冬小麦产量和水分利用效率的影响.结果表明:不同处理下冬小麦生育期土壤水分变化趋势一致,表现为播前至返青期稳定升高,返青至抽穗期急剧降低,之后至成熟期又逐渐回升,其中返青期到抽穗期土壤耗水量最大.增施氮肥或追氮可增加土壤耗水量,试验年份生育期间土壤水分变幅较大的活跃层逐渐加深,水分变幅较小的相对稳定层也相对下移,追氮可显著提高旱地冬小麦产量.垄膜沟播种植可减少土壤水分损耗,提高水分利用效率,两年分别比传统种植模式高23.4%和39.1%(P<0.05).垄膜沟播+追氮处理的小麦籽粒产量为3643kg·hm-2,显著高于单一垄膜沟播处理和追氮处理,水肥耦合效应较好.

| Abstract: | A 2-year (2008-2010) field experiment was conducted to study the effects of basal dressing nitrogen, topdressing nitrogen, and ridge film furrow planting on the 0-2 m soil moisture status and the grain yield and water use efficiency of winter wheat in rain-fed area of South Shanxi Province. In all treatments, the soil moisture status during winter wheat growth period had the same change trend, being increased steadily from pre-sowing to revival stage and decreased sharply from revival stage to heading stage... |
