[0002] In the artificial cultivation of forage grass, it is necessary to master the physiological characteristics of different forage grasses, and attention should be paid to scientific fertilization during the cultivation and management period. Before fertilization, the time, type and amount of fertilizer should be formulated according to soil conditions and forage grass types to meet the needs of forage grass growth, increase forage grass yield and quality per unit area, and ultimately lay a solid foundation for high and stable forage grass yields.

[0003] If the fertilization of artificial grassland is divided according to the time nodes, it can be divided into two types, namely, base fertilizer before sowing and topdressing during the growth period of forage. If it is divided according to the state of the fertilizer, it includes solid fertilizer and liquid fertilizer.

When applying solid fertilizer, the plug 36 can be a block-shaped structure with leakage holes on the surface, and the aperture of the leakage holes is larger than the particle diameter of the solid fertilizer. The tail butt joint pipe 32 is also equipped with a motor 1 53 and a motor 2 54 for driving the first outer cylinder 34 and the rotating cylinder 37 to rotate respectively (both existing micro motors can be used, and an external power supply can be used. Specifically, a battery pack for powering the electrical components in the device can be installed on the substrate 1).

[0049] Motor 2 54 drives the rotating cylinder 37 to rotate in the first outer cylinder 34, so that the feeding bin 38 intermittently takes materials and transfers the solid fertilizer from the fertilizer channel 19 to the discharge section 35; in this way, whenever the feeding bin 38 moves to the notch position, the fertilizer can enter the feeding bin 38, and the fertilizer entered into the feeding bin 38 is discharged when it moves to the discharge section 35, thereby completing each quantitative fertilization.

In this way, the application speed of the liquid fertilizer can be controlled by controlling the model and specification of the plug 36. The rotating cylinder 37 includes an inner cylinder 55 and a second outer cylinder 56 arranged coaxially.

[0051] Through the above scheme, the device can be used to apply liquid fertilizer and solid fertilizer, and because the position of the first outer cylinder 34 is adjustable, the position of the discharge section 35 also changes accordingly, so that the fertilization position can be changed, and different fertilizer bins 4 and feed pipes 6 are conveniently connected to save fertilizer replenishment time and improve fertilization efficiency.

The handle is provided with a positioning bolt that can be connected to the outer wall of the feed pipe to fix its position.

4. A high-efficiency fertilization device for forage planting as claimed in claim 3, characterized in that: A second annular groove is provided on the top of the tail butt joint pipe, and a first annular groove connected to the auxiliary material channel is provided on the bottom surface of the feed pipe. The first annular groove and the second annular groove form an annular cavity, and the annular fertilizing groove is connected to the annular cavity.

5. The high-efficiency fertilization device for forage planting as claimed in claim 4, characterized in that: A plurality of bulk material units are arranged in the annular fertilizing trough, and the bulk material units include a movable sleeve rotatably arranged on the inner wall of the annular fertilizing trough, and a plurality of shifting teeth distributed on the outer side of the movable sleeve, and the various bulk material units are connected by connecting rods to maintain synchronous rotation. An annular plate is installed in the annular cavity, and the annular plate is connected to the adjacent movable sleeves. A micro motor is also installed in the tail butt pipe, and a micro gear is connected to the output end of the micro motor, and a gear ring meshing with the micro gear is installed on the inner side of one of the movable sleeves.

6. The high-efficiency fertilization device for forage planting as claimed in claim 5, characterized in that: The moving mechanism comprises two main moving wheels symmetrically installed on both sides of the base, a bracket connected to the base, and a secondary moving wheel installed at the tail of the bracket.
