The moldboard plow, a remarkable tool in the agricultural field, has played an indispensable role in farming since its inception. From ancient plowshares to modern, high-efficiency plow blades, the evolution of the moldboard plow reflects the advancement of agricultural technology. It has not only improved tillage efficiency but also laid a solid foundation for stable and high crop yields. Let's delve into the world of moldboard plows and fully understand their amazing power.
　　The moldboard plow, this amazing farming implement for tilling land, uses its fully suspended design, with a heavy blade at the end of a beam, to easily attach to a team of draft animals or a motorized vehicle; even human-powered versions exist. Its function is to break up clods of earth, plow furrows, and fully prepare for sowing. Furthermore, the moldboard plow can break up plow pans, restore the soil's structure, thereby improving the soil's water retention and moisture preservation capabilities, while simultaneously eliminating some weeds, reducing pests and diseases, leveling the surface, and promoting the improvement of agricultural mechanization operation standards.
　　Structurally, the main plow body of the moldboard plow plays a core role. Through the collaborative work of components such as the plowshare and moldboard, it efficiently cuts, breaks up, and turns over clods of earth and weeds. The moldboard, also known as the plow mirror, comes in various types, including integral, composite, and slat types, while the plowshare, or plow blade, is structurally divided into triangular and trapezoidal types and can be further subdivided according to function.
　　In addition, the plow blade, as a key component in front of the main plow body and the small front plow, serves to vertically cut through the soil and weed residue, thereby reducing the resistance of the main plow body, reducing wear and tear, and ensuring neat furrow walls and improved covering quality. The rotary plow blade integrates multiple components such as a disc blade and a disc hub to achieve efficient cutting.
　　The subsoil plow, also known as a deep loosening plow, is installed below and behind the main plow body. Its function is to loosen the subsoil below the plow layer, achieving a deep loosening effect. Subsoil plows come in single-wing and double-wing types and are fixedly connected to the main plow body on suspended plows to ensure operational stability and efficiency.
