Summary: | The invention discloses a method for planting dry-land Brassica napus by using mulching film corn residual films, which is characterized in that the residual films are reserved after mulching film corns are harvested, and the Brassica napus is dibbled by using broken films according to the original specifications, i.e. the ridge width being 1.0m to 1.2m and the ridge spacing being 0.3m to 0.5m, the row spacing being 20cm to 23cm, the plant spacing being 25cm to 30cm, 0.2kg to 0.3kg of seeds per mu land and 5 to 8 grains per pit; when 3 to 5 main leaves grow from the Brassica napus, final singling of seedlings is completed at one step, two seedlings per pit are left and the density is controlled to be 18000 to 20000 plants per mu; and when 6 to 8 main leaves grow from the Brassica napus, the residual films are uncovered, intertillage soil loosing is conducted in combination with application of 8kg to 10kg of urea to promote the seedlings and the soil among ridges is lifted up to the ridges for planting the Bra |
