Online Data Collection System of Crop Infrared Canopy Temperature for Irrigation Control
The temperature difference between air and crop canopy,CATD,is a very economical and convenient index for irrigation decision-making.A new data collection system is presented for crop infrared canopy temperature to make irrigation decisions,which can avoid the expensive labor cost and the disadvantage of interrupted data serial by manual work..The main characteristics of the system are flexible and safe to run and operate.The results of the field experiments on winter wheat,indicate that the system is effective and veracious for application.Meanwhile,more issues and points will be explored and research will be done on the CATD.The next step of the CATD is mentioned along with the development direction and research subjects in field application.
