Background

The nutrient solution is prepared by dissolving compounds containing various nutrient elements necessary for plant growth and development and a small amount of auxiliary materials for prolonging the effectiveness of certain nutrient elements into water according to a certain amount and proportion.

In the crop cultivation process, the concentration of the nutrient solution needs to be detected in real time so as to meet the requirements of plant growth and development at different stages. EC values in solutions are currently generally measured by EC (conductivity) value meters to reflect the concentration of soluble salts. The main principle is that some salt compounds used for preparing nutrient solution are dissolved in water and then ionized into ions with positive and negative charges, so that the solution has a conductive function, and the conductive capacity can be expressed by conductivity, namely EC value. The conductivity of the nutrient solution changes along with the change of the nutrient solution degree, the EC value of the nutrient solution increases along with the increase of the concentration within a certain concentration range, and when the concentration of the nutrient solution is lower, the conductivity of the nutrient solution also decreases.

In the practical production, the concentration of all ions in the nutrient solution is uniformly reflected by the conductivity. The excess salts of non-nutritional ingredients are also reflected in the conductivity. This leads to a situation of high conductivity and low nutrient content.
