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。
Developed for the determination of crop canopy inside the micro-meteorology (temperature, humidity and wind speed) of the observation instruments. Four sets of temperature and humidity sensors and thermal ball-type wind speed sensors were calibrated in the laboratory and subjected to parallel contrast tests under natural conditions in the field. The results of maize observations are consistent with the microclimate’s basic rules and give more accurate and real-time measurements.
