摘要：An automatic precision irrigation control system for cotton field is presented in this paper, which consists of host computer, slave computer controller, different kinds of sensors, valve controller, communication module, and system software. The system can collect and monitor field environmental parameters such as soil moisture, soil temperature, atmosphere temperature, field evaporation amount and precipitation etc. By combining field environmental parameters with mathematical model, the irrigation time and irrigation quantity for cotton filed can be predicted. The different irrigation strategy can be adopted automatically according to the water-required rules of different cotton growing periods. This system had been used in the cotton field for precision irrigation in Langfang experimental farm of Soil and Fertilizer Institute, Chinese Academy of Agricultural Sciences from 2005 to 2006. Under the same environmental condition, the automatic irrigation system has higher cotton yield and uses less water quantity than the manual irrigation system. The results show that the automatic precision irrigation control system for cotton field can reduce irrigation cost and improve cotton yield.
