Abstract:

Potato is an important grain crop in northwest regions in China, and drought is one of the uppermost limiting factors in potato production. Based on the development trends of potato production of Gansu, Ningxia, Shaanxi, Qinghai and other provinces in northwest regions in the past 10 years, the paper had some analyses of reserves of water resources and the current situation of agricultural water in the area. Applications from the perspective of agricultural production, respectively towards engineering and facilities on water-saving technologies, agronomic water-saving technologies and structure-based water-saving technologies, the paper summarized the development of water saving cropping system on potato in northwest regions in China.
