The feasibility of solar water pumping system for Cassava irrigation in Guangxi Autonomous Region, China

Cassava is one of the most important cash crop in Guangxi Autonomous Region. The water demanded regulation of cassava is not coincident with the temporal and spatial distribution of precipitation. Irrigation is quite necessary for the growth of Cassava. Solar water pumping system is an effective way for Cassava irrigation. In this paper, the temporal and spatial distribution of Cassava is analyzed first. The potential and distribution of solar energy is also discussed. Considering the main factors including precipitation and slope to analyze the feasibility of solar water pumping system for Cassava irrigation. The results indicate that the Cassava appropriated for solar water pumping cover718 thousand and 500 hectares. The best matching region covers in 623 thousand hectares.
