Method and system for reducing greenhouse gas emission from farmland

Abstract

The invention discloses a system for reducing greenhouse gas emission from farmland, and relates to the technical field of greenhouse gas control. The system comprises a computer, a cloud informationbase, a field controller, a water pump, a water storage device and an aerator, wherein the cloud information base is used for receiving feedback signals of the field controller and sending corresponding instructions to the field controller, and pushing the feedback signals and sent instruction information to the computer in the form of logs simultaneously; the cloud information base communicates with the field controller through a wireless communication module; the water pump is controlled by the field controller and used for supplementing a paddy field with circulating water containing bubbles to inhibit survival of anaerobic microorganisms in the paddy field. The water pump has the beneficial effects that water is delivered into the paddy field in a circulating water mode, dissolved oxygen in the paddy field can be greatly increased, survival of the anaerobic microorganisms in the paddy field can be inhibited, and emission of methane can be effectively reduced; moreover, the water pump has a simple overall structure, has a remote control function, and can realize automatic operation.

Description

technical field [0001] The invention relates to the technical field of greenhouse gas control, in particular to a method and system for reducing farmland greenhouse gas emissions. Background technique [0002] A large amount of greenhouse gas emissions lead to global climate change, especially climate warming, which has become a frequent topic in recent years and has attracted great attention from governments and scientists. The International Climate Change Conference has been held for many years, focusing on government and academic The community explores greenhouse gas emission reduction technologies and studies the adverse effects of climate change on human beings. It is generally believed that there are six types of greenhouse gases, carbon dioxide, methane, nitrous oxide, fluorocarbons, water, ammonia, etc. Among them, carbon dioxide, methane, and nitrous oxide are mainly related to agriculture and farming activities.

Problems solved by technology

[0003] Such as CN103688727A, a farmland greenhouse gas emission reduction technology and its application; CN106045772A, a microbial product that effectively reduces farmland soil greenhouse gas emissions and its preparation method and other patents, which have proposed a good method to solve farmland greenhouse gas emissions, but very Obviously, it is suitable for dry land. For paddy fields, especially paddy fields where rice is grown, organic matter and soil organic matter mainly composed of rice root exudates and exfoliations produce methane through anaerobic fermentation under the action of methanogenic bacteria. The above-mentioned patent It cannot solve or reduce greenhouse gases such as methane produced in paddy fields, and has strong application limitations
