Deep scarification, fertilization and wide-width precision seeding method

Abstract

The invention discloses a deep scarification, fertilization and wide-width precision seeding method. The method comprises the following steps of 1, adjusting the fertilizer output amount of a deep fertilizer output port in the upper side of each deep fertilizer guide plate by utilizing a fertilizer adjuster; 2, adjusting the depth limiting amount of a profiling depth limiting transmission press wheel; 3, connecting a traction machine; 4, conducting fertilization and seeding preparation; and 5, conducting deep scarification, fertilization and wide-width precision seeding. The method integratesdepth limitation, straw removal, deep scarification, layered fertilization of reserve fertilizer in the growth period, rotary tillage, ditching, shallow fertilization in the germination period, wide-width precision seeding and earthing pressing, fertilizer required by crops in different growth periods can be applied to different soil layers at a time while deep scarification is conducted, one-timefertilization is achieved, and later topdressing is not needed; and during seeding, expanded-system wide-width seeding with one input path and two output paths is realized, seeding operation is completed at a time, the consistency of crop seeding depth is improved, and neat, strong and uniform seedlings are easy to realize, so that the crop yield is increased, and adjustment is convenient duringuse.

Description

technical field [0001] The invention belongs to the technical field of wide-width precision seeding with deep loosening and fertilization, and in particular relates to a wide-width precision seeding method with deep loosening and fertilization. Background technique [0002] Modern agricultural planting has basically realized mechanization, but usually crops are sown using no-till sowing, shallow rotary sowing and other farming modes. However, for crops, most of the roots are distributed in the 10-40cm soil layer, so the soil layer structure and soil properties have a great influence on the growth of crops and the shape and quantity of roots. Due to the insufficient depth of no-tillage or rotary tillage, it is easy to form a hard plow bottom layer at the bottom of the soil, and the active soil layer on the surface becomes smaller, which has a significant impact on the growth of crop root systems. Moreover, continuous topdressing is required in different growth periods of cro...

Problems solved by technology

The existing wide-width precision seeder for fertilization is difficult to control during the wide-width fertilization and seeding, resulting in time difference when the seeds fall to the ground, which in turn leads to uneven sowing, resulting in inconsistent emergence of seedlings, and even the extreme phenomenon that seedlings cannot emerge. It has become a bottleneck problem affecting the promotion of sowing methods. These problems directly affect the final yield of crops and urgently need to be resolved
