2009
The utility model provides a maize precision no-tillage sowing subsoiling compound working device, which comprises a frame which is hitched with a tractor, wherein the frame is provided with a fertilizer box and a seed box, and a fertilizer opener and a seeding opener are arranged on the lower portion of the frame. The maize precision no-tillage sowing subsoiling compound working device is characterized in that the front portion of the seeding opener arranged on the lower portion of the frame is provided with a subsoiling scoop and depth stop ground wheels, and the rear portion of the frame is provided with seeding press wheels. The subsoiling tillage depth of the maize precision no-tillage sowing subsoiling compound working device can be 20-40cm, firstly breaks the bottom layer of a hard plow, which is formed by rotary tilling for consecutive years, leads crop roots to downwardly extend, thereby absorbing more nutrients, and also more resistanting to lodge. Secondly, because the bottom layer of a plow is broken, the upper and lower permeability of plough layer soil is improved, which leads the proportion of three phases of solid, liquid and gas to be more coordinating. The maize precision no-tillage sowing subsoiling compound working device has the characteristics of multiple functions, excellent operation, high work efficiency, low fuel consumption, steady and reliable performance, strong applicability and easy operation and the like, and accords with the demands of conservation tillage of China.
