A water and fertilizer integrated intelligent irrigation system

Abstract

A water and fertilizer integrated intelligent irrigation system is used to realize the intelligent irrigation of water and fertilizer. It includes: an online detection system, the main water and fertilizer pipeline is connected with several water and fertilizer branch pipelines, and the water and fertilizer branch pipelines correspond to the crop units one by one. The first measurement pipeline obtains water and fertilizer from the water and fertilizer main pipeline and transports it to the control room. The branch pipeline obtains water and fertilizer and transports it to the control room, and the third measurement pipeline obtains water and fertilizer from the recovery pipeline and transports it to the control room; the soil analyzer corresponds to the crop unit one by one, the soil analyzer is connected to the PLC controller signal, and the PLC controls The device is connected to the pipeline switch signal set on the water and fertilizer branch pipeline; the water and fertilizer preparation system realizes the preparation of the water and fertilizer required by the crops through the accurate measurement of solid fertilizer; the recovery and disinfection system includes: collection mechanism, collection box, disinfection box and recycling cans. The invention can prepare water and fertilizer with required fertility according to the needs of crops, and can recycle and sterilize the water and fertilizer to save resources.

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
