Effect of the Flow Rate on Plant Growth and Flow Visualization of Nutrient Solution in Hydroponics

In hydroponics, the flow pattern of nutrient solution in a cultivation container affects growth plants. Even if rate is same between containers, may differ based on size and shape containers. Therefore, cannot be comprehensively described by alone. order to identify relationship plant growth, root morphology, uptake, pattern, hydroponic Swiss chard was carried out. addition, describe specific container, patterns were observed via field visualization using particle image velocimetry. As result, with increase rate, it found that can form an ideal for growth. Under this absorption promoted roots are elongated, thereby absorbing more nutrients further promoting However, when exceeds value, hindered. summary, identifying hydroponics facilitate better crop production.
