The invention discloses a light and simple mechanical potato planting device and method in the technical field of agricultural planting, and the method comprises the following steps: 1, selecting and preparing a land, and carrying out deep ploughing and fine
soil preparation by adopting a rotary cultivator 3-4 days before
sowing, with the rotary
tillage depth being 25-30 cm; 2, seed potatoes are prepared, and the
cut seed potatoes are subjected to seed dressing treatment after being diced; 3, preparing a base
fertilizer containing
phoxim for preventing and treating underground pests; 4, a light and simple potato planting device is used for carrying out compartment opening and ridging, the
sowing depth is accurately controlled, and when base
fertilizer is applied, compound
fertilizer is applied at intervals to seed potatoes, so that
bud burning and seed rotting are avoided; 5, medium-term management, wherein 5-7.5 kg of
urea is applied per mu according to the
seedling condition for
seedling lifting. The potato ridger is efficient and practical, manpower consumption of potato
sowing, fertilizing and ridging is reduced through mechanical application, the structure of the ridging
shovel is optimized, the planting efficiency and quality are improved, potato planting is simplified and efficient, labor intensity and planting cost are reduced, and the planting efficiency and quality are improved.
