Abstract

The invention relates to a variable irrigating fertilizing device, and a control method thereof, and belongs to the technical field of irrigation fertilization. The variable irrigating fertilizing device comprises a water flow solenoid valve, a flow transmitter, a mixing buffer tank, three mother liquor tanks, three mother liquor solenoid valves, a cleaning solenoid valve, and a controller; a water inlet of the mixing buffer tank is connected with an outlet end of the flow transmitter; an inlet end of the flow transmitter is connected with an outlet end of the water flow solenoid valve; an inlet end of the water flow solenoid valve is connected with a water source main pipe; a water outlet of the mixing buffer tank is connected with an inlet of a micro-irrigation pipe network; a cleaning outlet of the mixing buffer tank is connected with an inlet end of the cleaning solenoid valve; and the water flow solenoid valve, the flow transmitter, the three mother liquor solenoid valves, and the cleaning solenoid valve are connected with the controller respectively. The variable irrigating fertilizing device is simple in structure, and is capable of realizing automatic controlling of simultaneous irrigation and fertilize of a plurality of fertilizer solutions; fertilizing concentration and fertilizing amount are not influenced by inlet water flow; no external powder is need for water-fertilizer mixing; and energy consumption is low.

Description

technical field [0001] The invention relates to a variable-variable irrigation and fertilization device and a control method thereof, belonging to the technical field of irrigation and fertilization. Background technique [0002] Micro-irrigation system plays an increasingly important role in the development of facility agriculture, water-saving agriculture and ecological agriculture. As the main content of micro-irrigation system, fertigation is an important technical means to achieve high yield, high efficiency and high quality of crops. [0003] At present, the commonly used irrigation and fertilization methods at home and abroad include mechanical injection, hydraulically driven proportional fertilization pumps, differential pressure fertilization tanks, and Venturi fertilizers. The mechanical injection type has the advantage of uniform concentration of the input fertilizer liquid, but it requires pumps and power devices, which requires a large investment in equipment an...
