Abstract: With ‘Weike 702’ as test material, the author adopted 2 kinds of tillage methods under plastic-film mulching: sub-soiling measures (FS) and rotary tillage (FR), to research the effect of different tillage methods on the change rule of spring maize dry matter accumulation and transportation. Results showed that: after silking, dry matter accumulation of rotary tillage and ridging with plastic film munching was significantly higher than that of sub-soiling and ridging with plastic film munching, and the difference increased with the development process. FR had higher dry matter accumulation rate and longer duration time than FS. Dry matter transportation, transfer efficiency and grain contribution of FR were significantly higher than that of FS, and the performance in different organs was leaf > srem > ear.
