A recirculated hydroponic system for strawberry nursery production in plant factories
Plant factories could be used as a bioreactor for the production of disease-free and plant growth regulator (PGR) free daughter plants in strawberry. The recirculated hydroponic system often results in growth retardation and physiological disorders in strawberry. An improved recirculated system provided an environment with stable electrical conductivity (EC) and pH, which enabled strawberry plants to grow much more vigorously and to produce more runners. The concentrations of NO3-, K+, Ca2+, Mg2+, and SO42- in the solution were measured, and the ion content and consumption in the solution was calculated. A new solution was designed to reduce the frequency of solution renewal and to release the plants from suffering the accumulation of certain ions, according to the solution analysis. To reduce labor costs, cultivation supports for easy rooting were also tested.
