The invention discloses an efficient planting device for agricultural planting. The device comprises a greenhouse body and a greenhouse ceiling, water collection tanks are arranged at the tops of theouter sides of both the left side and the right side of the greenhouse body, filtering nets are arranged at the tops of the water collection tanks, the bottoms of the water collection tanks are both connected with water accumulation boxes through lower water pipes, the water accumulation boxes at the left side and the right side are both connected with spraying pipes located at the upper sides inside the greenhouse body through connection water pipes, and water pumping pumps are connected to the bottoms of the connection water pipes. According to the efficient planting device for agriculturalplanting, rainwater can be effectively collected and utilized to conduct irrigation, the using cost of the greenhouse is lowered, the effects of conducting ventilation and maintaining the indoor temperature and humidity to be stable can be achieved, the planting effect is improved, a fan is arranged in the channel, through a controller, a walking mechanism is controlled to move, a sunshade screenis driven to be unfolded, the temperature inside the greenhouse is lowered, and the greenhouse does not need to be manually covered with the sunshade screen, besides, salt for melting snow can be uniformly sprayed to the greenhouse ceiling in the circumferential direction, the spraying effect is good, the coverage area is large, and the snow melting effect is good.
