The invention discloses an
ecological environment-friendly agricultural
greenhouse irrigation system which comprises a
greenhouse body. A net-shaped steel reinforcement framework is arranged on the inner wall, close to the upper end, of the
greenhouse body, a
water storage tank is arranged at the upper end of the net-shaped steel reinforcement framework and positioned in the net-shaped steel reinforcement framework, an observation window is arranged on the side wall of the
water storage tank, water outlets are formed in two side walls of the
water storage tank, the upper side walls and the lower side walls of the water outlets are provided with cambered surfaces, the
water storage tank is communicated with a main
pipe through the water outlets, a plurality of
branch pipes are communicatedon the side wall of the main
pipe, vertical portions of the
branch pipes are provided with hoses made of rubber, spraying mechanisms are arranged at the lower ends of the
branch pipes, and two
water supply mechanisms are arranged in the
water storage tank and comprise placing boxes arranged on the inner wall, close to the upper end, of the
water storage tank. According to the
irrigation system, alot of time and energy of farmers can be saved, excessive water sources cannot be wasted, and the
irrigation system can prevent death of crops in some area caused by drought due to no irrigation.
