The utility model provides a wheat deep scarification rotary tillage layer by layer manuring zonation seed broadcaster relates to wheat seeding machinery technical field. Rotary cultivator attachment the place ahead is equipped with the deep scarification and divides layer depth fertilizer injection unit, and the rotary cultivator attachment rear such as is equipped with at dark broadcast application device, and the rear of waiting dark broadcast application device such as is equipped with at the dark device of sowing seeds, waits the rear of the device of sowing seeds deeply to be equipped with the suppression device. The deep scarification divides the layer depth fertilizer layering that fertilizer injection unit executed to execute below the rotary tillage layer, and lower part in the rotary tillage is intraformational is executed to the fertilizer that waits dark broadcast application device to execute, and the seed that waits the device of sowing seeds deeply to broadcast sowing lies in the intraformational upper portion of rotary tillage, in each rotary tillage in -band layer by layer manuring with sow seeds. The utility model discloses an inferior can accomplish with advancing deep scarification, deep deep placement slow release fertilizer, etc. Spread fertilizer over the fields deeply base manure, etc. Broadcast sowing operations such as seed, earthing, suppression deeply, can effectively improve fertilizer use efficiency, promote wheat seedling stage and later stage to grow, reduce and remain fertilizer to the pollution of soil and groundwater, promotion wheat increasing yield and income, reduction manuring late operation, energy -conservation, high efficiency.
