| 摘 要： | 根据河套灌区的气象、土壤、灌水等资料,利用ISAREG模型模拟了4种主要作物充分灌溉和非充分灌溉2种灌溉制度方案。根据模型的优化模拟结果分析,在作物产量比率仅略有下降的情况下,作物实施非充分灌溉将减少灌水次数和灌溉定额(平均下降45 mm),建议灌区把作物实施非充分灌溉作为一种节水措施之一。

| Abstract: | Using computer model, ISAREG, sufficient and deficit irrigation scheduling of four main crops were simulated based upon the daily meteorological data, soil data and irrigation water for Hetao Irrigation District in north China. The results showed that the irrigation times and irrigation water can be reduced (45 mm less on average) with only slightly yield decrease. Thus, the deficit irrigation was recommended as an effective way to save water in this District. |
