AI Technical Summary

Technical Problem

In existing technologies, oxygen or ozone injection methods are typically used in hydroponic systems, which ignore soil factors and cannot meet the dynamic regulation requirements of irrigation water oxygen content or dissolved ozone concentration in soil cultivation systems. Furthermore, they cannot improve the redox state of the soil, thus affecting crop growth.

Method used

By obtaining rhizosphere detection results from the soil matrix, the content of oxygen nanobubbles, hydrogen nanobubbles, or ozone nanobubbles in irrigation water is adjusted by controlling the nanopump to generate regulated irrigation water, thereby optimizing the crop root respiration environment and soil redox state according to soil conditions.

Benefits of technology

It enables dynamic adjustment of the bubble content in irrigation water based on actual soil conditions, improving the root respiration environment of crops, eliminating harmful microorganisms, optimizing the soil redox state, and promoting crop growth.

Abstract

The application relates to the technical field of agricultural facilities, and discloses a nano-bubble irrigation control method, a controller and an irrigation system. The method comprises the following steps: obtaining rhizosphere detection results of soil matrix, controlling the content of oxygen nano-bubbles, hydrogen nano-bubbles and / or ozone nano-bubbles in irrigation water based on the rhizosphere detection results, generating adjusted irrigation water, and controlling an irrigation device to use the adjusted irrigation water to irrigate crops. On the one hand, the application can adjust the content of oxygen nano-bubbles in irrigation water according to the actual situation of the soil matrix to improve the respiration environment of crop roots, and adjust the content of ozone nano-bubbles in irrigation water to kill harmful microorganisms in the soil and irrigation water. On the other hand, the application can adjust the content of oxygen nano-bubbles or hydrogen nano-bubbles in irrigation water according to the actual situation of the soil matrix, thereby adjusting the oxidation-reduction potential value of the irrigation water, and further optimizing the oxidation-reduction state of the soil.
