Abstract

Although photovoltaic (PV) irrigation systems are widely used in China, feasibility assessment of these systems is important because of differences in the distribution characteristics of solar resources and crops. In this study, kiwifruit planting in Shaanxi province was considered, and a calculation model for PV irrigation system evaluation was developed. Based on the geographical distribution of kiwifruit planting, as well as the spatial and temporal distributions of solar energy in Shaanxi province, the application potential of PV irrigation for kiwifruit was investigated comprehensively from the perspectives of technology, economy and irrigation feasibility. The results showed that the proportion of the PV module scale to the irrigation scale in all the kiwifruit planting areas in Shaanxi province was far less than 1.5%, and there were no technical obstacles. In Baoji, Weinan, Hanzhong and Ankang, the annual cost of the PV irrigation system was greater than that of the diesel pump irrigation system. Regarding irrigation feasibility, farmlands with a slope of 0%–8.75% were considered highly suitable for installing a PV irrigation system. The results revealed 32,269 ha of farmland appropriate for PV irrigation among the 66,371 ha of kiwifruit in Shaanxi province.

光伏系统用于猕猴桃灌溉的可行性分析：中国陕西省案例研究

尽管光伏（PV）灌溉系统在中国得到了广泛应用，但由于太阳能资源和农作物分布特征的差异，对这些系统的可行性评估非常重要。本研究以陕西省猕猴桃种植为研究对象，建立了光伏灌溉系统评估计算模型。根据陕西省猕猴桃种植的地理分布以及太阳能的时空分布，从技术、经济、灌溉可行性等方面综合考察了光伏灌溉在猕猴桃上的应用潜力。结果表明，陕西省所有猕猴桃种植区光伏组件规模占灌溉规模的比例均远小于 1.5%，不存在技术障碍。在宝鸡、渭南、汉中和安康，光伏灌溉系统的年成本高于柴油泵灌溉系统。在灌溉可行性方面，坡度为 0%-8.75% 的农田非常适合安装光伏灌溉系统。结果显示，在陕西省 66,371 公顷猕猴桃种植面积中，有 32,269 公顷农田适合安装光伏灌溉系统。

期刊介绍： Human intervention in the control of water for sustainable agricultural development involves the application of technology and management approaches to: (i) provide the appropriate quantities of water when it is needed by the crops, (ii) prevent salinisation and water-logging of the root zone, (iii) protect land from flooding, and (iv) maximise the beneficial use of water by appropriate allocation, conservation and reuse. All this has to be achieved within a framework of economic, social and environmental constraints. The Journal, therefore, covers a wide range of subjects, advancement in which, through high quality papers in the Journal, will make a significant contribution to the enormous task of satisfying the needs of the world’s ever-increasing population. The Journal also publishes book reviews.
