| Abstract: | An observation system was developed to measure microclimate (temperature,humidit y 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.T he observation of microclimate was conducted in a maize field at Yucheng Experim ental Station in Aug.1999.The observation results showed good correspondence wit h basic principles of microclimate.This instrument gives a more precise and real -time measurements than previous ones |
