A method of deep loosening and fertilizing seedling belt rotary tillage precision seeding

Abstract

The invention discloses a precision sowing method for deep loosening and fertilizing seedlings with rotary tillage, which comprises the steps of: 1. using a fertilizer regulator to adjust the fertilizer output of the deep fertilizer output port on the upper side of each deep fertilizer guide plate; 2. determining the shallow layer The height of the fertilization mechanism; 3. Connect the tractor; 4. Preparation for fertilization and sowing; The invention realizes the cleaning of straws before subsoiling, and at the same time of subsoiling, fertilizers required for different growth periods of crops can be applied to different soil layers at one time, which provides a good environment for crops growth, realizes one-time fertilization, and does not need topdressing in the later stage, improving Fertilizer utilization rate, after deep loosening, a sowing seedling belt can be produced by rotary tillage, which can improve the consistency of sowing depth of crops, and it is easy to achieve uniform seedlings, strong seedlings, and even seedlings, thereby increasing crop yield. The remaining straw can be directly returned to the field through rotary tillage , can improve soil fertility, reduce planting links, effectively avoid straw burning, protect the agricultural ecological environment, and promote sustainable agricultural development.

Description

technical field [0001] The invention belongs to the technical field of precision sowing, and in particular relates to a method for precision sowing of deep loosening and fertilizing seedlings with rotary tillage. 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. But for deep-rooted crops, most of the roots are distributed in the 10-40cm soil layer, so the soil layer structure and soil properties have a great impact on the growth of deep-rooted crops and the shape and number of roots. Due to the insufficient depth of no-tillage or rotary tillage, it is easy to form a hard plow layer at the bottom of the soil, and the active soil layer on the surface becomes smaller, which has a significant impact on the root growth of deep-rooted crops. And in different growth periods of deep-rooted crops, continuous topdressing is required, and the l...

Problems solved by technology

However, after deep loosening, it is easy to produce large soil clods and straw to cover the seedbed. Such uneven soil will easily increase the difference in seed sowing depth, and the straw coverage will affect the seed emergence rate and the later growth of corn.
