The present invention relates to a planting base structure. The planting base is composed of a tank body. A planting groove provided with a top surface with an opening is formed at the tank body. Furthermore, at least one delivery flow channel coaxially extended is formed below the planting groove of the tank body. The delivery flow channel has at least one passage communicated with the planting groove above the delivery flow channel. Accordingly, the planting base can use the delivery flow channel below the planting groove to perform the circulated delivery of nutrient solution, water or air. By using the passage of the delivery flow channel to communicate the planting groove, the nutrient solution, water or air can be gradually permeated into the planting groove to provide crop root with absorption. The usage amount can be accurately controlled to reduce unnecessary waste, the delivering time and condition also can be controlled at the same time, and the growth conditions such as temperature, humidity, etc. in the planting groove can be further controlled. Thereby, the present planting base structure can effectively facilitate the growth and quality of crop.本發明係一種植栽座結構，該植栽座係由一槽體所構成，且該槽體上形成有一頂面具一開口之植栽槽，又該槽體於植栽槽下方形成有至少一道以上同軸延伸之輸送流道，且該輸送流道具有至少一連通上方植栽槽之通道，藉此，植栽座可以利用植栽槽下方之輸送流道來進行營養液、水分或氣體的循環輸送，並透過輸送流道之通道與植栽槽的連通，使營養液、水分或氣體能逐步滲透到植栽槽中，供作物根部吸收，且用量可以被準確控制，而能減少不必要的浪費，同時輸送的時間及條件也可以被控制，甚至進一步控制植栽槽內的溫度與濕度等生長條件，從而有效促進作物的生長及品質。
