A structure improvement of a flowerpot, comprising an outer basin and a built-in basin accommodated in the outer basin, the built-in basin having a plate body and a vertical pipe located in the center of the plate body, the plate body and the pipe The surface of the body is provided with a plurality of perforations, and any place of the plate body is provided with a vent pipe upwards, whereby an upper and a lower space are separated in the accommodating space of the outer basin through the built-in basin, and the upper space The system contains the cultivation soil and grows the crops. The space below can provide the accumulation of water, so that the cultivation soil can not only maintain humidity, but also prevent the crop from rotted roots, improve the survival rate of crops, and ensure the healthy growth of crops. The vent pipe extending upward from the built-in basin can also provide convection exchange between the accommodating space and the outside air, and also help to improve the heat dissipation effect, so as to enhance the practicality of the structure.一種花盆之結構改良，其包含一外盆以及容設於該外盆內部之一內置盆，該內置盆具有一盤體以及位於該盤體中央處之一直立管，該盤體以及該管體表面皆設有複數個穿孔，且該盤體任一處係往上設有一透氣管，藉此，經由該內置盆於該外盆之容置空間內分隔有上、下空間，該上空間係盛置培養土壤並種植作物，該下空間則能提供水分的積存，令培養土壤不僅能保持濕度，同時可避免作物產生爛根情況，提升作物種植的存活率，確保作物健康成長，此外該內置盆往上延伸之透氣管亦能提供該容置空間與外部空氣的對流交換，也有助於增進散熱效果，俾以增進結構之實用性。
