Abstract
An online phosphate nutrient estimation model is constructed by a regressive analysis method. Electrochemistry sensor technology is introduced to measure nitrogen nutrient, kalium nutrient, calcium nutrient and a PH.A method is put forward to make online analysis of nutrient solution in greenhouse agriculture. A real system of nutrient solution online analysis is constructed. All this makes a good base for the control of the nutrient environment in greenhouse agriculture
