What is the principle of a land preparation machine?

A land preparation machine is an agricultural machine that is mainly used to cultivate the land and create suitable soil conditions for sowing and crop growth. The principles of a land preparation machine mainly include the following aspects:

1. Tilling: The land preparation machine turns up the soil through a rotating blade or plowshare, breaking the original soil structure and loosening the soil.

2. Mixing: The turned-up soil is mixed with the soil below, which helps to evenly distribute nutrients and organic matter in the soil.

3. Leveling: The land preparation machine makes the soil surface flatter and reduces unevenness through leveling, providing a good foundation for sowing and crop growth.

4. Compacting: In some cases, the land preparation machine can also compact the soil moderately to reduce water evaporation and improve the soil's water retention capacity.

5. Weeding: Some land preparation machines are equipped with a weeding function, which can remove weeds while turning the soil and reduce competition during crop growth.

6. Subsoiling: Some land preparation machines can perform subsoiling operations, that is, loosening the deep structure of the soil through subsoiling plows without turning the soil to improve the ventilation and drainage performance of the soil.

The types and functions of land preparation machines vary depending on agricultural operation needs and soil types. Common ones include rotary tillers, plows, harrows, subsoiling machines, etc. Proper use of land preparation machines can improve land cultivation efficiency and increase crop yields.
