Deep scarification fertilization seedling belt rotary tillage precision seeding method

Abstract

The invention discloses a deep scarification fertilization seedling belt rotary tillage precision seeding method. The deep scarification fertilization seedling belt rotary tillage precision seeding method comprises the steps that 1, a fertilizer regulator is used for regulating the fertilizer output amount of a deep fertilizer output port in the upper side of each deep fertilizer guide plate; 2, the height of a shallow fertilization mechanism is determined; 3, a traction machine is connected; 4, fertil ization and sowing preparation are carried out; and 5, deep scarification, fertilization, seedling belt rotary tillage and precision seeding are carried out. Straw cleaning is achieved before deep scarification, fertilizers needed by crops in different growth periods can be applied to different soil layers at a time while deep scarification is carried out, a good environment is provided for growth of the crops, one-time fertilization is achieved, later topdressing is not needed, the fertilizer utilization rate is increased, a seeding seedling belt can be obtained through rotary tillage after deep scarification, and the consistency of crop seeding depth is improved; uniform, strong and uniform seedlings are easy to realize, so that the crop yield is improved, the residual straws can be directly returned to the field through rotary tillage, the soil fertility can be improved, the planting links are reduced, straw incineration is effectively avoided, the agricultural ecological environment is protected, and the agricultural sustainable development is promoted.

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...
