PROBLEM TO BE SOLVED: To eliminate concerns of spindly growth and root rot due to over moisture of culture soil in conventional methods, and to develop an eco-automatic water supply device for flowerpot enabling the preventive measures of mosquito mediated and pseudomonas aeruginosa infection in spite of being a bottom up watering method and enabling an automatic water supply system even to a conventional flowerpot which cannot automatically supply water, though a flowerpot with a pot bottom larger than a lid with a hole illustrated in Fig. 3 in the present application could not be watered.SOLUTION: A water storage container main body is installed on a lid having a hole, while inserting, into a through hole for a water pouring cylinder, the water pouring cylinder such as a reversal type water storage container in which the water pouring cylinder is integrally formed with the water storage container main body in the lid having the hole of a basin with a lid, the lower end of a hanging string for water absorption is inserted and penetrated into a pot bottom hole of a flowerpot and the flowerpot with the hanging string is set on the above-mentioned lid having the hole, the lower end of the hanging string for water absorption is submerged below the surface of the water within the basin having the lid, and thereby liquid is guided to the culture soil of the flowerpot having the hanging string by the capillary phenomenon.SELECTED DRAWING: Figure 1【課題】 従来の方法では培養土の過湿による徒長及び根腐れが懸念されるのでそれを無くす。また本願に記載の図3で示すところによる穴付き蓋よりも大きい鉢底の植木鉢には、従来は給水不可能であったが、自動給水不可能の従来式の植木鉢でも自動給水可能のシステムとする事、かつ底面給水方式でありながら蚊媒介及び緑膿菌感染症の予防対策が出来る等の植木鉢エコ自動給水器の開発を行う事等を解決しようとする課題とする。【解決手段】 蓋付水盤の穴付き蓋において、注水筒が貯水容器本体と一体成型された反転方式貯水容器等の上記注水筒を注水筒貫通用穴に差し込みながら上記穴付き蓋上に上記貯水容器本体を設置し、更に植木鉢の鉢底穴に吸水用吊紐の下方の端を挿入貫通して吊紐付植木鉢を上記穴付き蓋上に設置し上記吸水用吊紐の下端を上記蓋付水盤の水盤内水面以下へと水没させ毛細管現象により液体を上記吊紐付植木鉢の培養土に誘導する。【選択図】 図1
