1、 Construction background

Food security is a major issue related to the development of China's national economy, social stability, and national independence. Deeply implementing the strategy of "storing grain in the land and storing grain in technology" and building high standard farmland to improve comprehensive agricultural production capacity and ensure food security is a practical need. China is currently in a critical period of transition from traditional agriculture to modern agriculture. Building high standard farmland with drought and flood protection can effectively improve agricultural production conditions and enhance the equipment level of existing agriculture, thereby improving the utilization efficiency of existing arable land resources and land output efficiency. At the same time, it can also promote farmers' income increase and promote the virtuous cycle and sustainable development of agricultural ecological environment. Through land leveling, construction of farmland forest network, etc., the rural landscape can be improved and the image of the new countryside can be enhanced.

2、 Policy background

As early as 2014, the National Standardization Administration formulated and released the "General Principles for High Standard Farmland Construction" (GB/T30600-2014) to guide the construction of high standard farmland in various regions; In November 2019, the General Office of the State Council issued the "Opinions on Effectively Strengthening the Construction of High Standard Farmland and Enhancing the National Food Security Guarantee Capacity", requiring the standardization of construction standards and accelerating the revision of high standard farmland construction; In 2021, the State Council approved the implementation of the National High Standard Farmland Construction Plan (2021-2030); In 2023, the Ministry of Agriculture and Rural Affairs issued the Measures for the Quality Management of High standard Farmland Construction (for Trial Implementation). In particular, the No. 1 central document in 2023 pointed out that "we should strengthen the construction of high standard farmland. We should complete the annual task of building, upgrading and upgrading high standard farmland, focus on making up the shortcomings of soil improvement, farmland irrigation and drainage facilities, coordinate to promote efficient water-saving irrigation, and improve the long-term management and protection mechanism. We should formulate an implementation plan to gradually turn all permanent basic farmland into high standard farmland".

3、 Characteristics of High Standard Rice Field Science and Technology Park Construction

Compared to dryland fields such as corn, high standard rice fields have a very high demand for irrigation water. However, in most parts of China, the irrigation methods for farmland are still limited to traditional irrigation modes, which have a low degree of automation and cannot effectively control the amount of irrigation. This wastes water resources and causes significant waste of human and material resources. The concept of developing automatic irrigation systems for farmland is an important means of controlling and effectively utilizing water resources. It can accurately, timely, quantitatively, and effectively replenish water for crops, improve crop yield and quality, and save water, energy, and reduce labor costs.

*. Intelligent irrigation canal

Concrete constructed channels are prone to water seepage and corrosion, especially in the northeast region. Concrete constructed channels are not resistant to freezing and swelling, and are prone to cracking and collapse. Cracks can be seen everywhere in the channels, which can easily leave safety hazards. Especially for concrete channels without control valves, it is easy to cause flooding and waste of water resources. Composite glass fiber intelligent irrigation channel is a water conservancy facility product made of synthetic resin as the matrix and added with glass fiber reinforcement materials, specifically designed for high standard farmland drainage and side ditch drainage. It has the characteristics of corrosion resistance, tensile resistance, electrical performance, thermal performance, and good plasticity. Compared with traditional concrete foundation water channels, it has similar product and installation costs

The product has a longer service life and better quality, making it more suitable for promotion and use in cold weather in the north.

Especially, the composite glass fiber intelligent irrigation channel is molded into one piece, which is resistant to stretching, freezing and swelling. The interface is sealed with glue treatment, and the channel wall is smooth, making the irrigation efficiency high and saving water resources; Secondly, using ultra-low quantities of embankment soil can save land area; Thirdly, the installation is convenient, fast, and does not require post maintenance, saving costs; Fourthly, it has good UV resistance and a service life of over 20 years; The fifth is the overall light weight, fast installation, and convenient construction.

**. Intelligent irrigation equipment

Including integrated intelligent water channels (new composite materials), integrated intelligent water channel cover plates (new composite materials), integrated intelligent field water gates, integrated intelligent water channel gates, integrated water level and flow monitoring devices for open channels, ultrasonic water level and flow monitoring stations for main and branch channels.

Channel gates are intelligent gates integrated into channels made of new fiberglass materials. They have multiple control modes such as remote, timed, and automatic, and are compatible with both solar and mains power supply methods. They solve the problems of high personnel costs, long gate distances, and complex field terrain that cannot be opened and closed in a timely manner in traditional manual gates.

The water inlet and outlet valves (gates) of the field plot are installed at the water inlet and outlet of the field plot. The valves (gates) can be remotely controlled through mobile phones and computers, and water level sensors can also be configured. Setting the water level height can automatically perform drainage and irrigation work, controlling the water level at the set value height without the need for manual water monitoring. The field water level height can be adjusted according to the settings. When used in conjunction with a mobile water quality (environmental) monitoring recorder, it can automatically change water according to specific rules based on the pH and salinity of field water quality, reducing the pH and salinity content.

The mobile water quality (environment) monitoring recorder can be equipped with various water quality or environmental sensors to monitor the water quality of fields or water sources 24 hours a day. It can set alarms for water level or water quality data, and can also be linked to intelligent field plot inlet and outlet valves (gates) to automatically change water according to water quality.

Flow meters are divided into two types: flow velocity and open channel. Flow velocity meters are used in large main and branch channels to monitor, summarize, and analyze the inflow and outflow of all farmland covered by the main channel. The open channel flowmeter has the characteristics of high accuracy, large range, and strong stability. It is suitable for small channels such as ditches and agricultural channels to monitor and analyze the sub channels. It has the characteristics of fast response, strong flexibility, and low price.

The high-definition video encoder is integrated into the ball motherboard, making the infrared high-speed ball a pure digital network type high-definition infrared high-speed ball.

Environmental monitoring meteorological stations can be equipped with more than 30 types of sensors to provide 24-hour monitoring of small environmental climate information for the installation area, such as; Environmental data such as temperature, humidity, light intensity, rainfall, evaporation, etc. are reported to the cloud for retention, and can be viewed, analyzed, and summarized through mobile phones and computers; Accumulated data can be summarized and analyzed to prepare in advance to avoid the impact of environmental factors on agricultural production.
