The invention provides an experiment apparatus used for researching a technology for preventing and controlling the nutrition salt release of deposits. The experiment apparatus comprises: a prevention and control experiment container, wherein the sidewall of the prevention and control experiment container is provided with a sealable and closeable channel opening; a separation sheet being suitable for being inserted from the channel opening and being applied to the inner wall of the prevention and control experiment container; and a lifting mechanism arranged on the sidewall of the prevention and control experiment container and being suitable for driving the separation plate to rise to the top of the prevention and control experiment container. The experiment apparatus used for researching a technology for preventing and controlling the nutrition salt release of deposits can strictly simulate field environment conditions in order to solve the technical problem of lack of experiment apparatuses and methods used effectively simulating the prevention and control of modification materials on the nutrition salt release of the deposits in the prior art and to obtain the a complete modification material and deposits after the prevention and control experiment, and is good for researching the prevention and control process and mechanism of various modification materials on deposits, and the change conditions of the modification material and deposits after the experiment.
