| 摘 要： | 在陕西三原县进行裂区试验,研究了不同灌水量条件下扩蓄增容肥对冬小麦产量、水分与降水利用效率的影响.结果表明:①低灌水条件下秸秆配方处理冬小麦花期到成熟期表层土壤蓄水量基本没有变化,而废料配方与普通施肥处理的蓄水量减少5.68 mm和8.56 mm;高灌水条件下秸秆配方处理营养生长期耗水速率小,但其分蘖至越冬阶段耗水分别...

| Abstract: | Splitplotexperiment was conducted in Sanyuan of Shannxi province to study the yield and WUE of winter wheat under different amendment fertilizer at high and low irrigation.The main results were as followed:①Water storage of topsoil was basically no difference under treatment of amendment fertilizer of straw formula(AFS) in low irrigation,but water storage under treatments of amendment fertilizer of waste(AFW) and tradition pattern(TP) were respectively reduced 5.68 mm and 8.56 mm.Water consumption rate in vegetative period was slow of AFS in high irrigation,but the water consumption was respectively 11.5 mm and 12.72 mm more than AFW and TP treatment from tillering stage to winter period.②Difference of water deprivation between high irrigation and low irrigation was mainly occurred from vegetative period to reproductive stage;the water consumption rates had no significant difference during this time.Irrigation at seed filling stage made water consumption rate accelerated after a slow start,but a process "fast followed by slow" at low irrigation.③Whatever the irrigation modes,the yield and WUE of amendment fertilizer of straw formula are both the highest;the yield and WUE at high irrigation is 80% and 30% of which at a low irrigation.AFS can regulate soil water supply more efficiently than waste formula(AFW) and made soil sustained precipitation and irrigation effectively,thus mitigated drought and provided water condition for high yield of winter wheat. |
