摘　　要：研制成适用于测定作物冠层内部微气象(温度、湿度和风速)的观测仪器。应用4组温度与湿度感应器和热球式风速传感器于实验室进行标定,并在大田自然条件下进行平行对比检验。玉米观测试验结果符合小气候的基本规律,并给出更加精确和实时测量。An observation system was developed to measure microclimate (temperature,humidity and wind speed) within canopies of crops. Four groups of sensors are used,which are calibrated in laboratory,and compared and tested under natural conditions. The observation of microclimate was conducted in a maize field at Yucheng Experimental Station in Aug.1999.The observation results showed good correspondence with basic principles of microclimate. This instrument gives a more precise and real-time measurements than previous ones.
