The invention discloses an intersecting-free straw strip-shaped return-to-field cultivation method for maize tillage. The method includes the steps that 1, before crop seeding is performed, crop strawof a last season is smashed in situ, ridge clearing and strip gathering are performed for the first time, straw at strip gathering positions is mixed and stirred in a soil layer, first seeding stripsare formed at ridge clearing positions, and first return-to-field strips are formed at the strip gathering positions; 2, before crop seeding of a next season is performed, crop straw is smashed in situ, ridge clearing and strip gathering are performed for the second time, the straw at strip gathering positions is mixed and stirred in a soil layer, second seeding strips are formed at ridge clearing positions, and second return-to-field strips are formed at the strip gathering positions; in the two adjacent planting seasons, the positions of seeding strips and the return-to-field strips are interchanged or the second seeding strips horizontally move to the first return-to-field strips to form strip spacing tillage. The arable layer structure of virtuality and reality alternating is created,and the method has the advantages of non-tillage and deep tillage, effectively solves the key problems in straw returning to the field, and is also an effective way for construction of a reasonable arable layer on dry land and promotion of soil fertility.
