An environment-friendly water-saving plant pot includes a first pot body and a second pot body. The first pot body has a receiving space having an upward opening, and a water outlet hole formed in the receiving space. A protruding unit that has several reinforced ribs extends upwards from the periphery of the water outlet hole. The second pot body is disposed in the receiving space of the first pot body, and has a second receiving space having an upward opening. A plurality of through holes are circularly formed inside the second receiving space, and the second pot body extends from the bottom to form a cover that has a cover opening, and the opening of the cover opening and the protruding unit of the first pot body are spaced to form a gap.一種環保節水植栽盆結構,其係包含:一第一盆體及一第二盆體,其中,第一盆體係供第二盆體容設,第二盆體於底面向下延伸設有一罩蓋,罩蓋具有一罩口,罩口之開口係與第一盆體之凸垣保持相隔而形成有一夾縫;藉由上述結構,儲水時形成具有可蓄水及可自行排水的密閉空間,利用此一結構水吸熱蒸發成氣體體積膨脹而形成正壓的水氣不致溢散到盆外只能往根部土壤送,從而潤濕土壤,進而自動供給植栽物所需之水分,藉此讓第一盆體所蓄積的水能反覆進行蒸發及凝結之循環過程,俾達成長期自動供給植栽物水分之目的,進而讓植栽土壤能長期保持在溼潤狀態,而得以避免植栽物因缺水而枯萎,俾增進維護植栽物之便利性,亦可減少澆水次數進而達到節水的功能。
