The invention belongs to the technical field of agricultural planting and particularly relates to an agricultural intelligent soilless culture device. The agricultural intelligent soilless culture device comprises a culture unit, a liquid mixing unit and a controller, wherein the controller is used for controlling the culture device to work; the culture unit comprises a culture tank, a filtering plate, a clamping component, a sliding rod, a spring I, a mounting plate, a hinging rod and a swing plate; the culture tank is of a transparent tank body structure with an opening upper side surface soas to facilitate the observation and is used for culturing plants, and the filtering plate is arranged in the culture tank; the sliding rod is arranged and is used for driving the swing plate to swing leftwards and rightwards in a nutrient solution, so that the flow of the nutrient solution in the culture tank is realized, nutrients in the nutrient solution are uniformly distributed, the growth vigor of the plants is probably the same, and the quality of the plants are easily controlled; and by arranging the liquid mixing unit, the efficient preparation of the nutrition solution is realized,and the prepared nutrition solution can be relatively high in uniformity.
