The invention relates to a cassava cultivation method applicable to whole-process mechanical operation. The method includes: rotary
tillage and ridging, to be specific, mechanically scarifying a landparcel, smashing soil, smoothening the land surface, and adopting a two-
ridge or four-
ridge ridger for rotary
tillage and ridging to make required ridges, wherein the ridges are in shapes of isoscelestrapezoid, and line spacing between every two adjacent ridges is in a manner of alternate narrow line spacing and wide line spacing; cassava selection; cassava seed stem planting; field management, to be specific, manually completing operation of filling gaps with seedlings and
thinning; mechanical completion of intertillage, weeding, fertilization and top dressing;
disease and pest prevention and control; harvesting, to be specific, before harvesting, adopting a
tractor for traction of a cassava
straw smashing and returning
machine to realize cassava
straw smashing and returning; adopting the
tractor for traction of a two-row four-
shovel vibratory cassava digger for digging and harvesting. By adoption of the cassava cultivation method, whole-process mechanical operation of the cassava planting industry can be realized beneficially, planting cost is reduced, and the
profit rate of the cassava planting industry is increased.
