Maintaining root vitality is the biggest advantage of Aeroponic grow system. Maintaining root vitality is a key factor to ensure the normal and efficient growth of plants. The roots of plants are important organs for absorbing water and nutrients. They are also important sensors for sensing environmental signals and realizing self-regulation of plant growth to ensure that root vitality is to maintain the vitality and normality of the above-ground parts. The core technology of fast-growing farming. Traditional methods are realized through scientific management of soil, fertilizer and water. For example, field loose soil is an important measure for root pruning to promote growth and improve soil gas phase. High-ridge and border planting is also an important method for improving soil permeability and timely drainage. In particular, drought and heat shock in the soil environment caused by the hot season are the main environmental signals that affect photosynthesis and normal transpiration above ground. Stomatal regulation and transpiration inhibition are used to maintain metabolic balance. These stressful environmental stimuli will directly or indirectly affect roots. The maintenance of vitality and the expansion and regeneration of the root system.
