The invention discloses a minimum tillage and no-tillage planting method for flax in southwest arid areas. Base fertilizer is directly applied and seed furrows are formed for seeding of the flax while land is moist, and seed dressing with chitosan oligosaccharide is performed while seeding. The method solves technical problems of high soil disturbance and serious soil moisture loss caused by existing planting methods for the flax in the southwest areas, the tillage cost is reduced, the flax planting benefit is increased, and meanwhile, carbon emission is reduced. The method has the characteristics different from conventional planting methods for the flax in the southwest areas as follows: 1, seeding is performed in advance by the aid of residual moisture, the irrigation cost is saved, and yield increase of the flax is facilitated by early seeding; 2, drainage and irrigation ditches are not formed, and the land utilization area is increased; 3, the high seeding density is adopted, and small ...
