Abstract:
In the paper, the tests and demonstration on a micro-irrigation system,which using photovohaic pumping technology have been introduced. The authors have also put forward a method to calculate the water requirement for crops and the energy demands for trickle irrigation systems in arid and semi-arid areas, and carried out the economic analysis on the photovohaic pumping micro-irrigation technology. Through the analysis, the authors concluded that the cost of water pumping by using photovohaic pumping technology is 0.073 RMB/m^3, which is only one third of the cost of using diesel engine.[著者文摘]
