A plant pot includes a pot having an enclosed space and a room defined therein. The room receives soil therein. At least one passage communicates with the room and the enclosed space. A tube is connected to the pot and has a path defined axially therethrough, the path respectively communicates with interior and exterior of the enclosed space. A resistance member is located in one end of the tube and has multiple micro paths which communicate with the interior of the enclosed space. A resistance is formed when exterior air passes through the tube and the resistance member so as to control speed and volume of the exterior air into the enclosed space.本發明係關於一種植物盆結構,其至少有:一盆體,其內形成有密閉狀的容置空間、一可供土壤容置用的容置槽、以及至少一連通容置槽與容置空間的通孔;至少一引流滲水件,其係組設於通孔內,且於引流滲水件形成有複數個微引道,並使引流滲水件二端分別與容置槽、容置空間形成連通狀的接觸;至少一導管,其係組設於盆體上,且導管內形成有一中空貫穿狀的通道,並使該通道二端分別連通至容置空間的內部及容置空間的外部;另,導管的一端組設有一具微引道的阻力件。10...盆體101...第一主體102...第二主體103...密封件11...容置槽12...容置空間13...通孔16...第一結合部17...第二結合部3...引流滲水件30...粒子30’...粒子31...微引道4...導管40...通道5...阻力件50...粒子50’...粒子51...微引道
