中文摘要	于20082010年,在山西省临汾市尧都区半干旱、半湿润季风气候区,通过大田试验研究了玉米秸秆连续还田条件下灌水模式对冬小麦籽粒产量、干物质转移及水肥利用效率的影响．结果表明:浇越冬水可促进小麦分蘖;浇拔节水可提高分蘖成穗率,增加成穗数;浇孕穗水可促进穗部干物质积累,提高千粒重．浇2水时,推迟第2次浇水时期使叶片干物质转移量和穗粒数增加;浇2水比浇1水的肥料表观利用率高,可促进穗部干物质积累．越冬水灌水量和总灌水量对分蘖、穗部干物质积累的影响较小;拔节期或孕穗期增加灌水量则更有利于养分吸收及干物质积累与转移,提高籽粒水分利用效率,产量构成因素协调,增产效果明显．因此,确保越冬水可实现稳产,在越冬水基础上,拔节期增量灌水(900 m~3·hm~(-2))可满足冬小麦中后期生长发育的需要,提高籽粒水分利用效率,实现节水高产栽培。
英文摘要	In 2008-2010,a field experiment was conducted to study the effects of different irrigation modes on the grain yield,dry matter translocation,water use efficiency(WUE),and nutrient use efficiency(NUE)of winter wheat under maize straw returning to the field in a semi-arid and semi-humid monsoon region of Linfen,Shanxi Province of Northwest China．Irrigation at wintering time promoted tillering,irrigation at jointing stage increased the total tiller number and the fertile spike rate per tiller,whereas irrigation at booting stage promoted the dry matter accumulation in spike and increased the 1000-kernel mass．When the irrigation was implemented at two growth stages and the second irrigation time was postponed,both the dry matter translocation to leaf and the kernels per spike increased．Irrigation twice throughout the whole growth season induced a higher NUE and higher dry matter accumulation in spike,as compared to irrigation once．The irrigation amount at wintering time and the total irrigation amount had lesser effects on the tillering and the dry matter accumulation in spike．Increasing irrigation amount at jointing stage or booting stage more benefited the nutrient uptake,dry matter accumulation and translocation,and grain WUE,which in turn made the yield-formation factors be more balance and the grain yield be higher．It was concluded that to guarantee the irrigation amount at wintering time could achieve stabilized yield,and the optimal irrigation mode was irrigation at wintering time plus an additional irrigation at jointing stage (900 m~3·hm~(-2)),which could satisfy the water demand of winter wheat at its mid and later growth stage and increase the WUE of grain,and realize water-saving and high-yielding cultivation．
