摘要

Owing to the difference of soil water in the farm, a system of variable rate irrigation was developed with Visual C++ and MapObjects that can save water as well as can improve economy benefit. Soil water content can be forecasted by using the forecast model of soil water, according to the real soil water content of different sampling sites in this system. Irrigation or not can be decided by comparing the current soil content with the light drought and serious drought index of the crop. The water amount of irrigation can be decided by the analysis of economy benefit according to the model of water consumption-yield, thus the irrigation prescription map can be created. This system can also query the information of fields, manage and analysis the data of soil. The test was performed in national precision agriculture demo farm.
