Single-phase fertilization-with-water system having double nutrient solution concentration output and using metering pumps for quantitative control

Abstract

The invention relates to a single-phase fertilization-with-water system having double nutrient solution concentration output and using metering pumps for quantitative control. The fertilization system comprises a raw water irrigation system, a fertilization system and an irrigation control system, wherein a shut-off valve a is arranged between a filter a and a raw water pump; the raw water pump is connected with a shut-off valve b; a filter b, a pressure gauge and a turbine flowmeter are arranged on the pipeline connected with the shut-off valve b and a check valve; a first chemical agent barrel is connected with a first metering pump, the first metering pump is connected with a first back pressure valve and a first stirring pump is connected with the first chemical agent barrel; a second chemical agent barrel is connected with a second metering pump, the second metering pump is connected with a second back pressure valve and a second stirring pump is connected with the second chemical agent barrel; the fertilization system is connected with a PLC irrigation control cabinet of the irrigation control system through the first metering pump and the second metering pump and the raw water pump, the first metering pump and the second metering pump are all single-phase motors. A detection module comprising pH value and EC value sensors are mounted on a main pipeline close to the irrigation region.

Description

technical field [0001] The invention belongs to the field of irrigation agriculture, in particular to a fertilization system with water and a fertilization control device thereof. Background technique [0002] With the rapid development of facility agriculture in my country, the area of ​​facility agriculture cultivation is also increasing. The traditional fertilization and irrigation methods are cumbersome and not conducive to saving water resources. Opportunities, but also put forward higher requirements. The water fertilization system combines irrigation and fertilization to make full use of water sources and fertilizers, so as to save resources and increase crop yields, save labor and improve efficiency. [0003] At present, the automation degree of drip irrigation system for fertilization with water is not high, especially for the situation where several different fertilizers need to be applied at the same time, there is no good solution, and the control system is not p...
