Advantages of Bench-Based Ebb-and-Flow Irrigation Systems

The ebb-and-flow bench irrigation system is a broad term encompassing ebb-and-flow irrigation, bench irrigation, and ebb-and-flow benches. "Ebb-and-flow irrigation technology supplies nutrient solution from the base of the crops, ensuring a uniform, rapid, precise, and highly efficient delivery of water and nutrients to the substrate. This method helps reduce air humidity within the facility environment, thereby minimizing the incidence of crop diseases; furthermore, it facilitates automated control, leading to savings in labor and production costs. Consequently, it represents an inevitable trend in the advancement of plug seedling cultivation."

Plants treated with ebb-and-flow irrigation exhibit vigorous growth and possess a high seedling robustness index. This method achieves water savings of 24% to 33.72% and demonstrates high irrigation efficiency, resulting in a 27.95% reduction in labor requirements. Moreover, by precisely controlling the inflow and outflow rates of the nutrient solution—ensuring rapid filling and draining—the system limits the substrate's water absorption volume. This mechanism effectively reduces the susceptibility of seedlings to pathogen infection, thereby minimizing the need for pesticide application.
