| 摘 要： | 根据FAO-56作物需水量指南推荐的作物系数计算方法,分别计算内蒙古河套灌区磴口试验站小麦、玉米(覆膜与未覆膜)、油料向日葵3种作物的单、双值作物系数。结果表明,磴口试验站单值作物系数较双值作物系数值计算的ET值偏低,双值作物系数计算的ET值与实测结果更为接近,验证了双值作物系数在河套灌区的适用性。 |

| Abstract: | According to FAO Irrigation and Drainage Paper No.56 Crop Evapotranspiration(guidelines for computing crop water requirements) recommend calculation of crop coefficient were calculated Hetao Irrigation Dengkou Experiment Station 3 crops such as spring wheat,summer maize(plastic-mulched and unplastic-mulched),oil sunflower of single and dual crop coefficient.The results show that ET calculated by single crop coefficient than the low dual crop coefficient.And the value of ET calculated by dual crop coefficient much closer to measured values for in the experimental station of Dengkou in Hetao irrigated area. |
| Keywords: | crop coefficient ET FAO-56 spring wheat summer maize oil sunflower |
