Water and fertilizer integrated intelligent irrigation system

Abstract

A water and fertilizer integrated intelligent irrigation system is used for achieving intelligent irrigation of water and fertilizer. The system comprises an online detection system, a water and fertilizer preparation system and a disinfection recycling system, wherein a water and fertilizer main pipeline communicates with a plurality of water and fertilizer branch pipelines, the water and fertilizer branch pipelines are in one-to-one correspondence with crop units, a first measurement pipeline obtains water and fertilizer from the water and fertilizer main pipeline and conveys the water and fertilizer to a control chamber, a second measurement pipeline obtains water and fertilizer from the water and fertilizer branch pipelines and conveys the water and fertilizer to the control chamber, and a third measurement pipeline obtains water and fertilizer from a recycling pipeline and conveys the water and fertilizer to the control chamber; soil analyzers are in one-to-one correspondence withthe crop units, the soil analyzers are in signal connection with a PLC, and the PLC is in signal connection with pipeline switches arranged on the water and fertilizer branch pipelines; the water andfertilizer preparation system is used for preparing water and fertilizer required by crops by accurately measuring solid fertilizer; and the disinfection recycling system comprises a collecting mechanism, a collecting box, a disinfection box and a recycling tank. The water and fertilizer with required fertility can be prepared according to the requirements of crops, the water and fertilizer can be recycled and subjected to disinfection recycling, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer integration, in particular to a water and fertilizer integration intelligent irrigation system. Background technique [0002] Water and fertilizer integration technology refers to a new agricultural technology that integrates irrigation and fertilization. It uses a pressure system (or natural terrain drop) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the law and characteristics of crop types. The mixed fertilizer solution and irrigation water are supplied with water and fertilizer through the controllable pipeline system. After the water and fertilizer are mixed together, drip irrigation is formed through the pipeline and the dripper, and the root system of the crop is uniformly, regularly and quantitatively infiltrated in the growth area, so that the main root system soil Always maintain looseness and appropriate water content; at the same tim...

AI Technical Summary

Problems solved by technology

[0003] The core point of water and fertilizer integration technology lies in the supply of the first water and fertilizer, the precise application of water and fertilizer, and the sterilization of water and fertilizer. In the existing water and fertilizer integration technology, due to factors such as human factors or imperfect equipment, it is highly dependent on manpower and cannot be realized. Problems such as precise supply of water and fertilizer according to crop demand lead to increased labor costs, and the actual implementation effect of water and fertilizer is not as expected, which also affects the later data collection and evaluation of integrated water and fertilizer technology
