The water tank 12 is filled with a decomposition liquid to help the decomposition of the straw, so as to accelerate the process of converting the straw into soil fertility. In the present application, the decomposition liquid is preferably water.

[0058] The implementation principle of the soil fertility restoration device according to an embodiment of the present application is as follows:

[0059] After the soil is turned by the soil turning structure 3, the soil is transported into the mixing bin 5 through the bucket 6 and the lifting transmission belt 7 during the movement of the frame 1. The straw in the bin 4 is sequentially crushed by the crushing roller 22 and the crushing ring 23 under the action of gravity, and then enters the mixing bin 5.

[0060] At this time, the soil and the straw in the mixing bin 5 are uniformly mixed under the stirring of the stirring roller 51. Finally, the mixed soil falls to the bottom of the mixing bin 5 under the action of gravity, and is discharged to the land through the discharge port 52.

[0061] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application.
