No-tillage seeder should have good passing performance in order to assure the quality of field operation. In the article, it aimed to improve the part of cutting stubble and avoiding block of type 2BQMJ-2 seeder, meanwhile observe the passing performance of the improved machinery by field tests, inspect the quality of cutting stubble operation, and verify working stability and rationality of structure design for the improved part. The result showed that the structure of the improved part is logical, its operation effect is good, and the passing performance in the field is improved.
