| 摘 要： | 小麦间作向日葵是一种典型的河套灌区种植模式,研究运用WIN ISAREG模型确定了参考作物蒸发蒸腾量,结合立体种植特征,采用综合作物系数法确定小麦间作向日葵全生育期作物耗水量。同时通过实际处理结果对模型参数进行率定与验证,最终对小麦间作向日葵实际灌溉制度进行准确的评价并进行不同方案的优化,得到试验区如配有井灌等条件,优选灌溉方案为土壤含水率下降至适宜含水率70%时实施灌溉,灌水量为补充根系层水量至田间持水量85%所需水量;若灌水水源仅为黄河水,则优选灌溉方案为整个生育期灌5水,灌水量为达到根系层中总有效水量的80%。 |

| Abstract: | Wheat interplanting sunflower is a typical planting mode in Hetao Irrigation Area.By using WIN ISAREG model,this study calculates the reference crop evapotranspiration on the basis of the characteristics of intercropping planting,using the integrated crop coefficient method to determine the wheat intercropping sunflower crop water consumption in whole growth stages.And at the same time through practical results of verified model parameters,finally,actual irrigation system and optimized different scheme of wheat intercropping sunflower evaluated accurately.Optimization irrigation scheme is implementing irrigation when the soil water content down to 70% of the appropriate moisture content,the water of the root layer reaches 85% of field capacity then stop the irrigation.If only the Yellow River water for irrigation water,the optimization scheme is irrigation five times in the whole growth period,then irrigation stops when water reaches 80% of the total effective water in the root layer. |
