Description

technical field

[0001] The invention belongs to the technical field of agricultural machinery, in particular to a traction-type hole-depth-adjustable punching machine. Background technique

[0002] Soil salinization refers to the process in which the salt in the bottom soil or groundwater rises to the surface with the capillary water, and after the water evaporates, the salt accumulates in the surface soil. Soil salinization is one of the most prominent production eco-environmental problems in arid and semi-arid agricultural regions in the world, the main obstacle to the sustainable development of regional agriculture, and the most common land degradation process. Soil salinization is not conducive to plant growth, affects yield, and threatens the sustainable development and utilization of regional land resources.

[0003] Among the existing measures to remediate degraded soil, the most common way is land leveling. Leveling the land can make the water infiltrate evenly, im...
