摘要
对宁夏扬黄延伸限额灌溉工程供水工程运行成本、作物种植成本、种植效益进行测算,开展不同补灌方式、作物种植下限额工程运行经济评价,研究不同作物在限额灌溉方式下实现经济效益的产量平衡点,通过种植户对限额灌溉工程的接受程度分析,提出不同限额灌溉方式在宁夏限额灌溉区的推广潜力。
Based on the calculation of the irrigation project operation cost, planting cost and benefit, the economic evaluation of the supplementary irrigation project under different irrigation methods and crops in Ningxia is carried out in this paper, and the input- output balance yield is put forward, too. By analyzing the acceptance degree of farmers for supplementary irrigation proiect, the pro- motion potential of different irrigation methods in supplementary irrigation area of Ningxia is studied.
