Abstract: For the problem of measuring nutrient solution composition in greenhouse agriculture, an on-line measuring system is designed and realized by Borland Delphi6.0. It measures the real-time values of nutrition solutions temperature, pH, EC andnn No3- ,k+ ,Ca2+ ion concentration, also provides history data for inquiry and analysis. Practical application shows that this system can satisfy the further need of implementing automation and doing research in greenhouse agriculture.
