摘  要：
通过田间试验研究了灌水次数对春小麦产量的影响,研究结果表明:减少灌水和灌水次数对春小麦产量并无显著影响,但随着灌水次数的减少,春小麦的灌溉水生产率却大幅度上升。从水资源高效利用的角度而言,综合考虑春小麦不同生育时期对水分的需求特点和土壤水分的消耗规律,春小麦以全生育期灌2水(分蘖水和灌浆水)为宜。

摘  要：
The effect of irrigation frequency on the yield of spring wheat was studied though field experiment.The result shows that it is no significant effect on yield of spring wheat to reduce irrigation frequency and irrigation application,and that irrigation water productivity of spring wheat rises extensively along with reduction of irrigation frequency.From the point of view of effective use of water resources,and considering the characteristic of spring wheat water requirement and the rule of soil water consumption at every growing stage of spring wheat,it is optimum practice that there are two times irrigation application(tillering stage and grain filling stage)within whole growing season of spring wheat.
