摘　　要：结合甘蓝型油菜渝黄一号田,研制出自动灌溉控制系统。应用RSC-2510DS太阳能电池作为系统的能源供给,自制经济土壤湿度传感器并用MATLAB标定得出土壤湿度-电压模型,由MCU AT89S51和ADC0809芯片等组成数据处理控制模块。解决了根据土壤墒情和农林作物需水规律进行节水自动灌溉的问题,满足了用户对系统环保、经济、节能的要求。The automatic irrigation controlling system for the field of rape-Yuhuang No. 1 （Brassica napus L） is designed in this paper. The RSC-2510DS Solar cell supplies energy for the system. The Soil Humidity Sensor is designed by self and the Soil Humidity -Voltage Model is gained through calibration by MATLAB software. The data processing and controlling model is composed of the MCU AT89S51 and the chip ADC0809, etc. This system solve the problem of water-saving and automatic irrigation according to the law of water requirement and soil moisture of agricultural and forestry crop and can fulfill the requirements of user on the environ mental protection, economy and energy saving.
