摘要: 作物系数和水分生产效率是分析评估灌溉用水定额和灌溉效益的基础参数，本文基于滴灌灌区生产实际调研采用数理统计方法，对12种大田滴灌作物系数和灌溉水分生产率进行了分析，结果表明：全生育期滴灌春麦作物系数和水分生产率为0.79、1.52 kg/m3；滴灌水稻作物系数和水分生产率为1.04、0.76 kg/m3；滴灌土豆作物系数和水分生产率为0.74、8.08 kg/m3；滴灌谷子作物系数和水分生产率为0.70、2.04 kg/m3；滴灌大豆作物系数和水分生产率为0.83、0.87 kg/m3；滴灌油菜作物系数和水分生产率为0.89、0.54 kg/m3；滴灌葵花作物系数和水分生产率为0.85、0.82 kg/m3；滴灌甜菜作物系数和水分生产率为0.64、17.05 kg/m3；滴灌打瓜作物系数和水分生产率为0.78、0.55 kg/m3；滴灌蕃茄作物系数和水分生产率为0.81、24.12 kg/m3；滴灌胡萝卜作物系数和水分生产率为0.80、19.18 kg/m3；滴灌苜蓿作物系数和水分生产率为0.80、4.15 kg/m3。分析结果为滴灌作物需水量及灌溉水分生产效率评估提供了参考依据。
Abstract: Crop coefficient and water production efficiency are the basic parameters for analyzing and evaluating irrigation water quota and irrigation benefit. Based on the actual production investigation in drip irrigation area, the crop coefficient and irrigation water productivity of 12 kinds of field drip irrigation crops were analyzed by mathematical statistics method. The results showed that the crop coefficient and water productivity of spring wheat under drip irrigation were 0.79 and 1.52 kg/m3 during the whole growth period; rice coefficient and water productivity were 1.04 and 0.76 kg/m3; potato crop coefficient and water productivity were 0.74 and 8.08 kg/m3 under drip irrigation; millet crop coefficient and water productivity were 0.70 and 2.04 kg/m3 under drip irrigation; soybean crop coefficient and water productivity were 0.83 and 0.87 kg/m3 under drip irrigation; rape crop coefficient and water productivity were 0.89 and 0.54 kg/m3 under drip irrigation. The crop coefficient and water productivity of drip irrigation sunflower were 0.85 and 0.82 kg/m3; the crop coefficient and water productivity of drip irrigation beet were 0.64 and 17.05 kg/m3; the crop coefficient and water productivity of drip irrigation melon were 0.78 and 0.55 kg/m3; the crop coefficient and water productivity of drip irrigation tomato were 0.81 and 24.12 kg/m3; the crop coefficient and water productivity of drip irrigation carrot were 0.80 and 19.18 kg/m3; and the crop coefficient and water productivity of drip irrigation alfalfa were 0.80, 4.15 kg/m3. The results provide a reference for the evaluation of crop water requirement and irrigation water production efficiency under drip irrigation.
