1. Introduction

Paddy plow is a key tool used in rice cultivation, and its development process reflects the process of agricultural mechanization. Although the traditional manual plow was widely used in history, with the expansion of agricultural production scale and the improvement of mechanization level, the paddy field plow gradually evolved into a more powerful mechanical equipment. This paper will systematically review the development of paddy field plow, analyze its technological evolution and influence on agricultural production, and discuss the future development direction.

2. Origin and traditional form of paddy field plow

The use of paddy field plows can be traced back to ancient agricultural societies. Early paddy plows usually consisted of wooden or iron ploughs and simple ploughs drawn by human or animal power for plowing rice fields. This kind of traditional plow is low in tillage efficiency, but the operation is simple and suitable for the agricultural production conditions at that time. The design of the traditional paddy plow mainly takes into account the special soil structure of the paddy field, emphasizing the sharpness of the plow head and the smoothness of the plow surface to reduce the resistance in the muddy soil.

3. The rise of mechanized paddy field plows

From the end of the 19th century to the beginning of the 20th century, with the deepening of the industrial revolution, mechanized paddy field plows began to appear. The earliest mechanized paddy plows were driven by steam engines or internal combustion engines, which significantly improved the efficiency of ploughing and reduced the manual labor of farmers. The key technological progress of mechanized paddy field plow is reflected in the following aspects:

- Power transmission technology: Early mechanized paddy plows are driven by chains or gears, transferring power from the engine to the plow for automatic ploughing.

- Plow material improvement: With the development of metallurgical technology, the plow material of paddy field plows has gradually changed from iron to steel, improving durability and working efficiency.

- Operational flexibility: Compared with traditional manual plows, mechanized paddy plows are more flexible in field operation and can adapt to different rice growing environments and soil conditions.

4. Development of modern paddy field plow

From the late 20th century to the 21st century, paddy field plows have achieved comprehensive modernization in technology, mainly in the following aspects:

- Multi-functional integration: modern paddy field plow not only has the function of ploughing, but also integrates a number of operation functions such as ditching, breaking soil, leveling, etc., realizing a multi-purpose machine and further improving production efficiency.

- Intelligent control: The paddy field plow equipped with electronic control system and GPS navigation can accurately control the ploughing depth and path, reduce manual errors, and ensure the uniformity and consistency of ploughing operations.

- Environmental protection and energy saving design: Modern paddy plows pay more attention to environmental protection and energy saving in the design, using low-emission engines and efficient energy transfer systems, reducing fuel consumption and carbon emissions.

5. Influencing factors of paddy field plow development

The development of paddy field plows is influenced by many factors, including technological innovation, agricultural demand, policy orientation and environmental factors. Technological innovation has promoted the continuous improvement of paddy field plows, such as advances in material science and power transmission technology, making paddy field plows more efficient and durable. Agricultural demand determines the direction of the paddy field plow market, for example, large farms need more powerful and durable machinery and equipment, and small farmer economies prefer small paddy field plows with higher flexibility. In terms of policy orientation, governments have promoted the popularization and replacement of paddy field plows through subsidies and policy guidance. Changes in environmental factors, such as the impact of climate change on rice planting patterns, have also driven improvements in the adaptability of paddy plows.

6. Future development trends and challenges

In the future, the development of paddy field plows will continue to advance in the direction of intelligence, multi-function and environmental protection. Emerging technologies such as artificial intelligence, Internet of Things, and big data will play a greater role in the design and operation of paddy field plows, and promote the comprehensive intelligence of agricultural machinery. In addition, as the global focus on sustainable agriculture increases, paddy plows will focus more on energy efficiency and environmental impact. However, the development of paddy field plows also faces some challenges, such as high costs that limit the use of some smallholder economies, complex mechanical structures that increase the difficulty of maintenance and operation, and adaptability in extreme climatic conditions.

7. Conclusion

The development history of paddy field plow reflects the progress of agricultural mechanization and the change of agricultural production demand. From traditional manual plows to modern mechanical plows, paddy field plows have continuously innovated in technology, significantly improving the efficiency and quality of rice production. Looking ahead, paddy plows will continue to play a key role in the modernization of agriculture, but at the same time need to address the challenges posed by high costs, complex operations and environmental changes.
