Soil pH monitoring and management method based on IoT (Internet of Things) technology

Abstract

The invention discloses a soil pH monitoring and management method based on an IoT (Internet of Things) technology. The method is characterized by being implemented through a device comprising a soilpH sensor and an information transmission system, wherein the soil pH sensor is used for collecting agricultural environment and density and height of crops; the information transmission system comprises a communication module and a communication gateway, the communication module is used for realizing communication of the collected data or control commands among the communication gateway, the soilpH sensor, a database layer and a control module; the communication gateway is used for distributing the data. The system is intelligently controlled to apply fertilizer according to soil types, cropspecies and growing periods, fertilization precision is improved, fertilizer is saved, meanwhile, the fertilizer enters the positions near crop roots with water, so that deep loss of the fertilizer is prevented, fertilizer efficiency is improved, and crop yield is increased.

Description

technical field [0001] The invention relates to the monitoring technology of the agricultural internet of things, in particular to a soil pH monitoring and management method based on the technology of the internet of things. Background technique [0002] Soil acidity and alkalinity refer to the existence of various chemical and biochemical reactions in the soil, showing different acidity or alkalinity. The strength of soil acidity and alkalinity is often measured by pH. The reason why the soil is acidic and alkaline is because there are a small amount of hydrogen ions and hydroxide ions in the soil. When the concentration of hydrogen ions is greater than the concentration of hydroxide ions, the soil is acidic; otherwise, it is alkaline; when the two are equal, it is neutral. my country's per capita cultivated land area and per capita water resources are only 30% and 25% of the world's average level, and 2 / 3 of the existing cultivated land is low-to-medium yield fields, and...
