Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, in particular to agricultural equipment for improving soil and a use method thereof. Background Art

[0002] Soil acidification can aggravate soil compaction, making it difficult for roots to extend, weak rooting ability, and difficult for seedlings to grow. It is easy to form old small trees, old and stiff seedlings, poor root development, reduced absorption function, weak growth, and reduced yields. To deal with soil acidification, you can spray pesticides to achieve the effect of adjusting the acidity and supplementing calcium in the soil. The existing soil acidification improvement process usually adopts manual spraying of pesticides, or uses simple agricultural tools as an aid, which not only has low work efficiency, but also consumes a lot of manpower.

[0003] For example, patent CN117121673A proposes a soil improvement device and method for alleviating soil acidification. The height of the shovel plate and the broken roller are adjusted according to the needs of use, making it more flexible to use. At the same time, the broken roller rotates above the shovel plate to crush the soil, so that the soil can be better integrated with the agent that alleviates soil acidification, thereby improving the quality of alleviating soil acidification.

[0004] In the above scheme, the soil is first scooped up directly by a shovel and then mixed with a neutralizer. However, the soil layer of the land to be reclaimed has a high density. It is difficult to shovel up the soil layer as a whole by simply relying on a shovel, and the damage of the shovel is also easy to increase. In addition, the soil mixed with the neutralizer after being crushed cannot be evenly returned to the original reclaimed ground, which leads to poor effect of improving the land.
