Abstract

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. The invention includes a water flow solenoid valve, a flow transmitter, a mixing buffer box, 3 mother liquor tanks, 3 mother liquor solenoid valves, a cleaning solenoid valve and a controller; the water inlet of the mixing buffer box and the outlet port of the flow transmitter The inlet of the flow transmitter is connected to the outlet of the water flow solenoid valve, the inlet of the water flow solenoid valve is connected to the main water source pipe, the outlet of the mixing buffer tank is connected to the inlet of the micro-irrigation pipe network, and the mixing buffer tank The cleaning outlet is connected to the inlet port of the cleaning solenoid valve; the water flow solenoid valve, the flow transmitter, the three mother liquid solenoid valves and the cleaning solenoid valve are respectively connected to the controller. The invention has a simple structure, can automatically control multiple fertilizer solutions to irrigate and fertilize at the same time, the fertilization concentration and fertilization amount are not affected by the inlet water flow, and the mixing of water and fertilizer does not require external power, and the energy consumption is small.

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...
