[0071] An organic agricultural biochar-based fertilizer and a preparation method thereof, which is customized using a set of special adaptive composting equipment, and the use method thereof is as follows: Step S1, raw material preparation: 30-40 parts of biochar, 3-15 parts of starch, 1-5 parts of deionized water, and 5-25 parts of inorganic fertilizer;

[0072] The raw materials are divided into multiple parts, and the present application selects five parts, that is, 30 parts of biochar, 3 parts of starch, 1 part of deionized water, and 5 parts of inorganic fertilizers are put into a single batch. The inorganic fertilizers are targetedly configured with nitrogen, phosphorus, and potassium fertilizers, that is, a relatively prominent amount of nitrogen fertilizer, phosphorus fertilizer, or potassium fertilizer is put into the plant growth trend, and the finished fertilizers in the later stage are made into three types of targeted biochar organic fertilizers; the above formula is divided into five equal parts and graded, which can also be: take 32 parts of biochar, 6 parts of starch, 2 parts of deionized water, and 10 parts of inorganic fertilizers. Compared with the above-mentioned ratio method, the specific gravity of biochar changes, the total amount of carbon source changes, and the stacking time of biochar-based fertilizers in the impregnation box 101 is changed at the same time. According to this method, the fertility of the finished biochar-based fertilizer can be changed, which is convenient for application in fertility improvement programs for different lands;

[0073] Step S2, mixing raw materials: mixing and crushing biochar and starch through a stirring component, filling the biochar, starch and part of the catalytic reaction components into the stirring component, using the stirring component to perform secondary crushing, and setting aside, multiple batches of raw materials are stirred and put in batches;

[0074] Step S3, layered stacking: Inorganic fertilizers are put into the preparation device in turn for crushing, and mixed raw materials are added for stacking, and deionized water is continuously added to maintain humidity, and the stacked biochar fertilizers are turned over regularly. A single batch of ground inorganic fertilizers is started by starting the stirring motor 119 on the inorganic crushing box 104 to drive the pickaxe ball 121 to crush the inorganic fertilizers and filter through the leak plate 122, and the stacking plate 123 is used to carry the inorganic dust of this batch, and then the stirring raw materials inside the mixed feed port 105 are filled to cover the inorganic fertilizers, and a single batch of deionized water is introduced. After the filling is completed, the next stacking plate 123 is stacked from top to bottom with the previous stacking plate 123 by driving the stacking plate 123 to move sideways and up and down, and then the next batch of inorganic fertilizers, mixed carbon raw materials, and deionized water are filled in turn, and the filling is repeated. The above five-group filling preparation method requires the use of at least 6 stacking plates 123, 5 of which are used for impregnation stacking, and the other is for carrying standby loading;

[0075] There are two ways of flipping and throwing the discharging method. The left cultivation chamber 102 and the right cultivation chamber 103 can be different temperature control areas, which is convenient for controlling the dryness of the finished fertilizer. It is practical and meets different land requirements. The discharging method can also be two-sided discharging. One is as follows: the bottom stacking plate 123, under the condition of immersion, due to the blending and infiltration of deionized water and powder, the biomass charcoal component of the fertilizer part in the upper layer is greater than that in the lower layer, and the content of inorganic fertilizer is slightly lower than that in the upper layer. Therefore, five kinds of biomass carbon organic fertilizers with different fertility are formed from top to bottom. The bottom stacking plate 123 is flipped first, and the receiving component 114 is opened to drive the bottom stacking plate 123 downward following the middle tooth groove 111 to the horizontal supporting position of the lower layer. Please refer to the following figure. Figure 3 The fertilizer inside the stacking plate 123 is flipped by lowering the position of the flipping assembly 113 on one side, so that it is flipped to the other side and guided to the left cultivation cabin 102 ( Figure 3 );

[0076] Steps S4, S4, layered discharging: the fertilizer after turning over is taken from bottom to top, dried, ash-formed and then packaged to obtain biochar fertilizer with different nutrient levels, and the load-bearing stacking plate 123 reserved in the left cultivation cabin 102 is driven again to engage and move upward for drying; when the two sides need to be dried separately or to different degrees, the stacking plate 123 can be manually filled through the bottom discharge port 129 and the turning and throwing components 113 on both sides are used alternately to turn the fertilizer in two directions. The taken out fertilizer stacking plate 123 has two different drying effects, and different adhesion effects can also be obtained during granulation; when taking the stacking plate 123, it is stacked from bottom to top into the recovery cabin 106. The fertility of the upper biochar fertilizer is slightly greater than that of the lower layer, and it has a certain grading effect, and can prepare a variety of biomass carbon fertilizers of different degrees in the same series. When applied to the same piece of land, it has a better selection and optimization effect, and can meet the growth needs of different lands and different crops.

[0077] In addition, refer to Figure 2 The movement mode of the fertilizer stacking plate 123 device of the present invention is as follows: the stacking plate 123 is filled from the bottom discharge port 129, and the end of the stacking plate 123 is a program-controlled driving gear 126. The driving gear 126 drives the four end points on both sides to rise and move inside the patrol guide frame 108 to the top to wait for filling. During filling, the end-mounted cylinder or the horizontal gear set 132 directly drives the lateral convex groove 133 to move horizontally to the main guide frame 112 on the upper part of the impregnation box 101. When the four corners of the end correspond to the lower vertical main guide frame 112 of the main guide frame 112, the driving gear 126 moves downward, and the above-mentioned steps S2 and S3 are implemented during the movement. The ventilation box body 107 of the lower layer is used to provide flowing air and exchange the two left cultivation cabins 102 and The heat flow in the right cultivation chamber 103, after a single batch of materials is filled, the next material is stacked, the transverse gear set 132 is an adaptive protruding component, which moves to form a stroke area covering the lateral convex groove 133, and after the stacking infection time is over, the lower stacking plate 123 is separated by releasing the supporting telescopic plate 115 and moved to the position of the lower main rail frame 112, and the transverse gear set 132 drives the stacking plate 123 to move to the left cultivation chamber 102 or the right cultivation chamber 103 side, driving it to move to the range of action of the flipping assembly 113 for reverse flipping. The above movement, flipping and stacking times can be multiple cycles. After the stacking plate 123 carries the fertilizer after flipping, the driving gear 126 moves upward again for timed drying of the material.
