Keywords: agricultural machinery; Automation; Development prospects

China is a large agricultural country, and the agricultural economy accounts for a significant proportion of the national economy. Accelerating the construction of agricultural mechanization and automation is a key factor in ensuring the rapid development of the agricultural economy and improving the level of rural economic development. It is also a highly valued issue by the agricultural technology department, the Party Central Committee, and the State Council. Agricultural machinery automation refers to the process of agricultural production that does not require direct manual labor, but is completed by mechanical automation equipment instead of farmers, thereby reducing workload, saving a lot of manpower and material resources, and improving agricultural production efficiency. Throughout the world, major agricultural countries such as the United States and Russia have basically achieved agricultural mechanization and automation. Often, a farmer can manage thousands of acres of land, greatly improving production efficiency. However, looking at the current situation of agricultural development in China, small-scale farming still dominates, and the task of building agricultural mechanization production is arduous and the road ahead is long. Therefore, it is necessary to continuously explore agricultural machinery automation production technology, improve agricultural production efficiency, and promote the continuous development of agricultural production technology towards high quality, high efficiency, and high precision.

1. Analysis of the current application status of agricultural machinery automation production technology in China

1.1 Application Status

1.1.1 Analysis of Common Agricultural Automation Production Technologies

The current agricultural automation production technology in China is mainly developed based on tractors and other machinery, and is mainly divided into several aspects such as automatic harvesting equipment, rotary tiller equipment, and combined sowing equipment. Agricultural tractors mainly use mechanical hydraulic three-point linkage position adjustment and force adjustment to control and adjust some peripheral agricultural machinery equipment, in order to improve production efficiency. Agricultural tractors have been introduced into China's agricultural production practice since 2000, and their efficient and labor-saving production methods have been widely welcomed by farmers, gradually becoming the main force in agricultural production. Since then, China's agricultural production has entered the era of mechanical automation. With the continuous development of agricultural machinery technology and the emergence of new farming concepts, agricultural machinery and equipment have been continuously improved and perfected, ensuring production efficiency while reducing human resource investment; In addition, some agricultural machinery and equipment can automatically adjust their own working power according to the external environment, such as grain dryers that can automatically adjust their power according to the humidity and temperature of grains, ensuring both drying efficiency and reducing energy consumption, which is also strongly advocated by modern production concepts.

1.1.2 Application of Automatic Irrigation Technology

Water saving automatic irrigation technology refers to the timed detection and analysis of soil moisture content in a field under the comprehensive automatic control of a computer system, drawing a moisture content curve, and manually setting a moisture warning line. When the soil moisture continues to be below the warning line, the computer system controls the irrigation machinery system to perform automatic irrigation, so as to maintain the soil moisture content within the range suitable for crop growth, ensuring that crops do not reduce yield due to lack of moisture. Compared with manual irrigation technology, automatic irrigation technology has the advantages of saving water, fertilizers, energy consumption, pesticides, and annual human resources, and can basically eliminate the impact of perceived factors, achieving long-term stable development of agricultural irrigation engineering. In order to prevent the impact of natural disasters such as floods and storms on agricultural production, the country has been piloting new irrigation technologies since 2010, and has achieved outstanding results, opening up an efficient path for the country's new agricultural infrastructure construction. In addition, the national technology department has never stopped exploring new agricultural irrigation technologies, and has successively developed new equipment such as hollow drip heads, micro spray irrigation technology, and flow irrigation equipment, and has basically achieved integration with automatic control systems, taking a new step towards the field of automatic control irrigation technology.

1.2 Constraints on the Development of Agricultural Machinery Automation Technology

1.2.1 Low technological content

The prominent problem in the promotion of agricultural mechanization technology is that the technological content is not high, and the scientific and technological literacy of the majority of farmers cannot meet the corresponding requirements. Many advanced mechanical equipment and production technologies face significant resistance in rural areas. In addition, compared to the early stage of reform and opening up, China's technological development has achieved remarkable achievements that have attracted worldwide attention, and the economic performance of our video industry has significantly improved. However, in agricultural production, the perfect connection between agricultural machinery automation technology and today's advanced technology has not been achieved. Many regions still use traditional manual farming techniques due to the limitations of local economic development history, geographical environment, and human environment. The agricultural civilization is still in the primary development stage, and there is still a big gap compared to other developed agricultural countries in the world. In addition, China's agricultural machinery and automation technology follow the development model of European and American countries, often without considering the actual national conditions and needs of our country, which is also a key factor restricting the mechanization of agricultural production in our country.

1.2.2 Outdated agricultural machinery production equipment

In the United States, Israel and other agricultural developed countries, advanced agricultural machinery production equipment and technology is an important guarantee for achieving Dafengshou (Salad of assorted fresh vegetables) of agricultural products. For example, in the United States, many farms are mechanized large-scale production, while in Israel, the government attaches great importance to agricultural production, using its abundant capital technology and technology reserves to establish automatic sprinkler irrigation systems in a large number of areas, making agricultural irrigation both water and labor saving, which can be described as killing two birds with one stone. However, looking at the agricultural production situation in China, many farmlands are located in hilly areas with uneven terrain, making it difficult to carry out large-scale mechanized production. Moreover, irrigation technology is mostly based on sprinkler irrigation, which is difficult to fully meet the water demand of crops.

2. Effective strategies for vigorously promoting the development of agricultural machinery automation technology

2.1 Implementing the Application of Computer Technology in Agricultural Production

Computer technology, especially computer vision technology, is a new type of agricultural production technology that countries around the world are competing to research. The application of this technology in agricultural production is mainly used in fields such as identifying the quality of agricultural products, observing the growth of agricultural products, and recording crop production information. In this respect, the British have taken the lead in the world. They have invented an automatic mushroom picking robot, which can automatically identify mature mushrooms using computer vision technology and achieve accurate positioning, measurement and recording. Therefore, China should vigorously promote the development and dissemination of computer vision technology, achieve automated management of agricultural production, and lay a solid foundation for the promotion of corresponding technologies.

2.2 Achieving Automated Assembly of Agricultural Machinery and Equipment in China

Installing automatic analysis and control systems in inherent agricultural machinery can effectively improve the work efficiency of agricultural machinery, resulting in a qualitative improvement in both practical and operational performance. If automation technology is integrated into tea making machinery, suitable power can be selected for operation based on the variety, type, and quantity of tea leaves, and a matching rolling program can be developed by combining different types of tea leaves, so that the force during the processing can be well controlled. The agricultural machinery and technology promotion department should be based on the basic national conditions of agricultural production in China, timely update and improve the inherent agricultural machinery equipment, try to install automatic control systems based on computer equipment in the existing agricultural machinery system, better meet the requirements of modern agricultural production in Yonghe, and achieve sustainable development of agricultural economy.

2.3 Implement automated control of agricultural product testing and packaging

The testing and packaging of agricultural products is a complex project that requires experienced technicians to identify and classify the maturity, color, etc. of agricultural products, and package and box them separately, thus consuming huge manpower and material resources. The automatic detection packaging machine can effectively solve this problem by using its built-in camera and X-ray detector to detect the degree of damage and disease situation of agricultural products, and to remember the maturity of agricultural products, selecting high-quality products for classification and packaging. At present, some countries and regions abroad have started to extensively use this new technology and have achieved significant results. With the continuous improvement of domestic agricultural letter sending level, farmers' cultural and technical skills have also been widely improved, and agricultural production is gradually transforming into an intensive production mode. In the future, automatic detection and royal protection technology for agricultural products will definitely be vigorously promoted and applied.

3. Conclusion

In summary, with the rapid development of science and technology, social economy, and information technology, automation technology has been well applied in agricultural production. To further promote the development of modern agriculture, in addition to addressing various constraints, it is also necessary to closely integrate with the actual situation of agriculture in China, conduct in-depth research on agricultural machinery automation technology, and fully leverage the value of mechanical automation technology in the development of modern agriculture. Only by taking multiple measures can we truly achieve the comprehensive and effective development of mechanical automation technology in modern agriculture.
