Layered fertilization mechanism and method

Abstract

The invention discloses a layered fertilization mechanism and method. The layered fertilization mechanism comprises a rotary tillage fertilizer dispersing device, a spiral fertilizer conveying device and a rotary driving device; the rotary tillage fertilizer scattering device is used for carrying out rotary type rotary tillage on the soil in the vertical direction, and scattering the strip fertilizer in each soil layer into each corresponding soil layer to form surface fertilizer; the spiral fertilizer conveying device is used for carrying out spiral conveying on the fertilizer, the spiral fertilizer conveying device is provided with fertilizer applying openings in the height direction, and the fertilizer applying depth of the fertilizer applying opening in the bottommost end is higher than the rotary tillage depth of the rotary tillage fertilizer scattering device; the spiral fertilizer conveying device comprises a fertilizer application guide pipe, the fertilizer application guide pipe is vertically arranged, a spiral forced material guide plate is fixedly mounted in the fertilizer application guide pipe, a spiral fertilizer application channel is formed between the spiral forced material guide plate and the fertilizer application guide pipe, and all the fertilizer application openings are communicated with the spiral fertilizer application channel; the mechanism can perform surface fertilization under soil, so that the utilization rate of the fertilizer is improved, the fertilizer dosage is reduced, and the fertilization effect is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a layered fertilization mechanism and method. Background technique [0002] Fertilizers can maintain and improve soil fertility and provide nutrients needed for crop growth. In addition to spreading basal fertilizers in the crop growth cycle, top dressing operations are also required in the middle and late stages of crop growth to ensure sufficient soil effort and meet crop growth needs. [0003] At present, the fertilization under soil is mainly through the fertilization mechanism, when the soil is turned over, the fertilizer is put under the soil, which is used to realize the fertilization of the base fertilizer and the seed fertilizer. , when fertilizers such as Image 6 As shown in one row, for the wheat that needs to be broadcast, the utilization rate of this kind of drilling fertilizer is low, and the amount of fertilizer is high. However, if spreading is us...

Problems solved by technology

[0003] At present, sub-soil fertilization is mainly to put the fertilizer under the soil when turning over the soil through the fertilization mechanism, which is used to realize sub-soil fertilization of base fertilizer and seed fertilizer. The fertilizer fertilized in this way is mainly in strip shape, that is, fertilizer bar application , at this time fertilizer such as Image 6 The graphs are concentrated in one row. For the wheat that needs to be sown, the fertilizer utilization rate of this kind of row sowing is low, and the amount of fertilizer is relatively high

And if sowing is used, that is, when the fertilizer is spread on the surface of the soil, the soil cannot enter the interior, and the fertilization effect is also low.
