PROBLEM TO BE SOLVED: To provide a liquid supply method capable of solving problems such as generating losses of culture solution and taking labor and time to carry out cleaning work or a tube replacement for preventing foul smell due to rotten remaining organic matter or closure of a tube due to precipitates.SOLUTION: A method for supplying a culture solution containing an organic liquefied fertilizer by using a tank, that is, supplying the culture solution to a plant without making the organic liquefied fertilizer rotten within the tank in solid medium cultivation and nutrient solution soil cultivation, includes a process (a) and a process (b). In the process (a), a predetermined amount of water and a predetermined amount of organic liquefied fertilizer are put into the tank as a culture solution, and the tank has an opening on the bottom surface thereof or on a side surface near the bottom surface. The culture solution is discharged from the opening, and supplied to the plant which is planted in a culture medium or a soil through a tube connected to the opening. The concentration of the organic liquefied fertilizer in the culture solution is not uniform. In the process (b), after the process (a), water is put into the tank, and discharged from the opening. A predetermined amount of water is supplied to the plant through the tube connected to a discharge port, and the organic liquefied fertilizer within the tank is removed.COPYRIGHT: (C)2015,JPO&INPIT【課題】培養液のロスが生じるばかりでなく、残留した有機物の腐敗による悪臭や沈殿物によるチューブの閉塞を防ぐための清掃作業やチューブの交換に手間がかかるといった問題を解決するための給液方法の提供。【解決手段】以下の工程を含む、タンクを用いて有機液肥を含む培養液を給液する、固形培地耕および養液土耕栽培において、有機液肥をタンク内において腐敗させずに培養液を植物に給液する方法:工程(a):底面又は側面の底面近傍に開口部が設けられたタンク内に所定量の水及び有機液肥を入れて培養液とし、該培養液を前記開口部から吐出し、該開口部に連結されたチューブを通して培地もしくは土壌に植え付けられた植物に与える工程、ただし前記培養液中の有機液肥の濃度は均一でない;及び工程(b):工程(a)の後、前記タンク内に水を入れ、該水を前記開口部から吐出し、吐出口に接続されたチューブを通して前記植物に所定量の水を与えるとともに、タンク内の有機液肥を除去する工程。【選択図】図1
