摘　　要：作物的水分生产函数是实行节水灌溉,适时适量进行灌溉的科学依据。本文以农大108玉米品种为试验对象,并以宽垄沟灌的种植灌水方式,采用田间分区对比试验,研究了农大108玉米品种的灌溉供水与作物产量的关系函数。作物在拔节期、穗期、乳熟期对水分的敏感指数分别为-0.37897、0.29816、-0.10581,穗期就成为作物灌溉供水的关键期,灌溉需首先满足本阶段作物需水。Crop-water producing function is the scientific basis of carrying out water saving irrigation timely and proper quantity. This paper studied the relation function between water supply in corn species called Nongda108 which is the study object of this experimentation and crop yield. It takes width ridge and furrow irrigation as the irrigation method and adapt simultaneous test in field which has been separated. During jointing stage, spike stage and milky ripeness stage, the water sensitive index are -0.37897, 0. 29816 and -0. 10581. So that the spike stage is the key stage, the crops water require should be satisfied firstly when irrigating in this stage.
