摘　　要：经过1995～1998年的田间试验,在摸清了鲁西南地区冬小麦需水特性的基础上,结合当地降水及其分布特点,提出了冬小麦非充分灌溉的灌水指标及优化运行模式。该灌溉模式与充分灌溉相比,在单产接近的条件下,减少了灌水次数,节省了灌溉水量,提高了灌溉水的生产效率,使有限的水资源得到充分利用。Irrigation index and optimization operation mode of deficit irrigation of winter wheat are proposed based on field experiment during 1995 - 1998, understanding of the water requirement characteristics of winter wheat in southwest Shandong Province, and incorporating the features of local rainfall and its distribution. Compared with sufficient irrigation, this irrigation mode, with close crop yield, decreases irrigation times, saves irrigation water, increases productivity of irrigation water and makes good use of limited water resources.
