宁夏作为我国的农业灌溉区和粮食生产基地地处西北内陆,地区水资源不足。宁夏银川市永宁县的黄羊滩农场现建成的10000亩葡萄园,水资源的特点是量少、难以利用,水量分配不均。现有的系统自动化程度不高,不能对作物实现精确的轮灌,对灌水时间和灌水量还不能实现精确的控制。通过对现有灌溉系统的分析,设想对其控制系统进行自动化改造,以提高灌溉效率。
As an agricultural irrigation area and food production base in China, Ningxia is located in the inland of Northwest China, with insufficient water resources. Ningxia Yinchuan Yongning County, Huangyang Beach farm is now built 10000 acres of vineyards, water is characterized by less, difficult to use, uneven distribution of water. The existing system is not highly automated and can not achieve accurate rotations of crops, and accurate control over irrigation times and irrigation volumes can not be achieved. Through the analysis of existing irrigation systems, it is envisaged to automate the control system to improve irrigation efficiency.
