PROBLEM TO BE SOLVED: To provide a liquid supply detecting equipment of high quality which detects the amount of liquid supply accurately and can be manufactured by simple constitution at a low cost, and provide a liquid supply detecting method and equipment using the method which can detect precisely the situation of a liquid supply part by using a simple means. SOLUTION: The liquid supply detecting equipment is provided with a small diameter type drip-feed hole 70 for dripping liquid in a drip type which liquid is supplied from the upper side of liquid supply direction to liquid supply path 60, and a pair of electrodes 71, 72 wherein an electrically continuous interval K of dripping liquid for making a current flow via the dripping liquid is formed on the lower side of the hole 70, and performs electrical detection by making the dripping liquid formed by the hole 70 pass the electrodes 71, 72. The liquid supply detecting method extracts the liquid supplied to the liquid supply part 3 from a liquid collecting hole 34, and detects electrically the amount of liquid by using the liquid supply detecting equipment 7. The using equipment of the liquid supply detecting equipment 7 is installed in an implantation bed 30 accommodating a culture medium W for a plant plantation. |
