The invention discloses a rainfall infiltration process and root growth dynamic comprehensive observing system. The system consists of an underground observation room, observation pools, an infiltration water collection system and a root observation window. The underground observation room consists of an observation room interior and an observation room exterior; the observation room exterior consists of the observation pools distributed around a ground observation room; the upper part of each observation pool is in a cube shape, the lower part of each observation pool is in a cone shape, and infiltration water collection pipes are embedded at the cone-shaped bottoms of the observation pools; the infiltration water collection pipes are connected with infiltration water collection funnels, water guiding pipe outlets extend to the observation room interior, water pipes are provided with valves, and infiltration water collection containers are arranged at the openings of the water pipes. The rainfall infiltration process and root growth dynamic comprehensive observing system provided by the invention is suitable for experimental study on such facts as rainfall redistribution processes of different types of vegetation and soil, a soil water movement and redistribution process, deep stratum supply characteristics, water quantity balance, plant and water relationships and root growth dynamics; scientific evidences are provided for mass-energy conversion and water resource utilization of atmosphere-soil-vegetation systems of arid areas and semi-arid areas, and adaptive processes and mechanisms of plants responding to a soil environment.
