The through grooves 13 are located at the bottom of the fertilizer cylinder 2 and communicate the inside space of the fertilizer cylinder 2 and the fertilizer cylinder 1. After the fertilizer liquid is added to the fertilizer cylinder 2, the fertilizer liquid in the fertilizer cylinder 2 flows into the fertilizer cylinder 1 through the through grooves 13. By arranging the through grooves 13 at the bottom of the fertilizer cylinder 2, it is helpful for the fertilizer liquid to flow into the fertilizer cylinder 1.

[0053] Referring to FIG. 1, Figure 6 As shown, the fertilizer cylinder 1 is provided with a plurality of through grooves 13 on the side surface in the circumferential direction. The through grooves 13 are located at the bottom of the fertilizer cylinder 2 and communicate the inside space of the fertilizer cylinder 2 and the fertilizer cylinder 1. After the fertilizer liquid is added to the fertilizer cylinder 2, the fertilizer liquid in the fertilizer cylinder 2 flows into the fertilizer cylinder 1 through the through grooves 13. By arranging the through grooves 13 at the bottom of the fertilizer cylinder 2, it is helpful for the fertilizer liquid to flow into the fertilizer cylinder 1.

[0054] The method for using the soil nutrient fertilizer device is as follows:

[0055] Firstly, before adding the fertilizer liquid, ensure that the discharge hole 12 is in a closed state, i.e. the cone 31 extends out of the discharge hole 12 to close the discharge hole 12. The user adds an appropriate amount of fertilizer into the fertilizer cylinder 2 according to the fertilizer demand, and the fertilizer flows into the fertilizer cylinder 1 through the through grooves 13.

[0056] Then, the user holds the handle 322 on both sides of the installation cover 321 with both hands, and presses the fertilizer device to insert the fertilizer cylinder 1 into the soil.

[0057] Then, the user reversely rotates the rotating block 324 on the installation cover 321, and the rotating block 324 drives the threaded rod 323 to rotate, the threaded rod 323 drives the threaded cylinder 325 to move upwards along the threaded rod 323, the threaded rod 323 drives the cone 31 to retract into the fertilizer cylinder 1, and the discharge hole 12 is opened. Slowly pulling the fertilizer cylinder 1, the fertilizer cylinder 1 is pulled out of the soil, and at this time, the fertilizer liquid in the fertilizer cylinder 1 can gradually leak out through the discharge hole 12 at the bottom end of the fertilizer cylinder 1 during the pulling of the fertilizer cylinder 1, and the soil fertilization is completed.

[0058] The soil nutrient fertilizer device provided by the utility model sets the discharge hole 12 at the bottom of the fertilizer cylinder 1, and cooperates with the adjustable mechanism 3 rotatably arranged in the fertilizer cylinder 1, the bottom of the adjustable mechanism 3 passes through the discharge hole 12, and the discharge hole 12 is closed.

[0059] The adjustable mechanism 3 includes a connecting rod 326 and a rotating assembly for controlling the rotation of the connecting rod 326, the discharge hole 12 is closed by arranging the cone 31 at the bottom of the connecting rod 326, and meanwhile, the bottom tip of the cone 31 helps the user to press the fertilizer cylinder 1 into the soil. When the user presses the fertilizer cylinder 1 into the soil, the discharge hole 12 is in a closed state, and the cone 31 extrudes the soil downwards to form a conical pit in the soil. When fertilizing, the cone 31 retracts into the fertilizer cylinder 1 by reversely rotating the rotating assembly, the discharge hole 12 is opened, and the fertilizer liquid flows into the soil. The existence of the conical pit avoids the soil from blocking the discharge hole 12 when the discharge hole 12 is opened. In addition, even if a small amount of soil adheres to the vicinity of the discharge hole 12, the cone 31 extends out of the discharge hole 12 by forwardly rotating the rotating assembly after the fertilization is completed, the soil adhered to the vicinity of the discharge hole 12 is removed, and the discharge hole 12 is closed, so that the discharge hole 12 is prevented from being blocked by the soil.

[0060] Since the discharge hole 12 is arranged at the bottom, when the fertilizer device is pulled out of the soil, the soil cannot immediately block the discharge hole 12 at the bottom due to the extrusion of the soil by the fertilizer device during insertion, so that the fertilizer device can continuously fertilize during the pulling process.

[0061] The periphery of the fertilizer cylinder 1 is provided with the feeding cylinder 2 communicated with the fertilizer cylinder 1, the top of the feeding cylinder 2 is provided with an open mouth, the user can pour the fertilizer liquid into the feeding cylinder 2 through the open mouth, and the fertilizer liquid can be poured into the fertilizer cylinder 1.
