In the utility model, the driving motor is driven main rotary lever, and the meshing transmission of driving nautilus gear and driven nautilus gear is used, and main rotary lever and vice rotary lever rotate simultaneously, and the all -round, multi -angle stirring of stirring rod to fertilizer is carried out, compared with traditional stirring mode, improves stirring efficiency and evenness, ensures that the nutrient of topdressing solution is balanced, is helpful to corn better absorption nutrient, promotes growth.

The application relates to the technical field of agricultural fertilizer stirring, and discloses an agricultural fertilizer stirring device, which comprises a box body, a smashing mechanism, a distributing mechanism and a stirring mechanism; the box body is used for supporting and mounting the whole device; the smashing mechanism, the distributing mechanism and the stirring mechanism are arranged in the inside of the box body from top to bottom; the smashing mechanism adopts two smashing rollers which rotate oppositely, cooperates with a bevel gear transmission assembly, can efficiently break up caked fertilizer, and lays a foundation for subsequent stirring uniformity. The distributing mechanism is intermittently meshed through a half gear and a full gear, periodically rotates a distributing cylinder, makes the fertilizer uniformly fall according to a set amount, avoids that excessive feeding at one time leads to excessive stirring load or uneven mixing. The stirring mechanism adopts a double-stirring-roller rotating design, stirring blades are mutually matched to form convection stirring, greatly improves the fertilizer mixing uniformity, guarantees the soil nutrient balance after fertilization, and improves the practicability of the device.

The utility model relates to a kind of efficient fertilization and mixing device for rhizoma polygonati planting, belong to rhizoma polygonati planting technical field. Mainly including support frame, walking wheel, traction frame, mixing box, stirring mechanism, discharging mechanism and fertilization component. Mixing box is equipped with stirring mechanism, stirring mechanism is driven by motor, can efficiently mix fertilizer;Discharging mechanism includes storage hopper, poking disc and discharge pipe, ensure that fertilizer is evenly conveyed;Fertilization component adjusts the spacing of fertilization pipe by mounting plate, adapts to different planting needs. The device realizes the efficient mixing and accurate fertilization of fertilizer by mechanization operation, reduces labor cost, avoids the problem of blockage, significantly improves fertilization efficiency and planting benefit.

The invention discloses a special organic fertilizer for preventing and controlling tobacco black shank and a preparation method thereof.The special organic fertilizer is prepared from corn straw, rice husk charcoal, a biological leavening agent, limonin, salicylic acid, plant ash, shrimp shell powder and soluble potassium silicate, and the biological leavening agent is tarlaromyces flavus powder; the preparation process comprises the following steps: acidizing the prawn shell powder, crushing and fermenting the corn straws, the rice husk charcoal and the acidized prawn shell powder, increasing the activity of the tarlaromyces flavus powder by using limonin and salicylic acid, carrying out secondary fermentation, and finally granulating and drying. The growth and development of tobacco root systems are promoted, the stress resistance of the tobacco is enhanced, and the occurrence of soil-borne diseases is reduced, so that the yield of the tobacco is increased. Meanwhile, the tobacco absorbs more comprehensive and balanced nutrients, and the internal quality of the tobacco leaves is improved.
