[0004] Although it achieves the goal of returning straw to rows, covering and shallowly pressing, deep loosening and shallow rotation, and synchronous pressing, it solves the problems of existing straw covering strip tillage machines that cannot adapt to small row spacing, have high requirements for straw pre-treatment, are prone to drag piles, cannot cover straw evenly, and have large and small seedlings after sowing;

[0005] However, the problem that the existing strip tillage machine is not conducive to conveniently adjusting the tillage depth and tillage spacing during use, is not conducive to adaptive tillage of land of different widths, and affects the flexibility of use. Utility Model Content
