[0028] By improving the design of the fertilizing and hole digging device, two hole digging and fertilizing frames are arranged to surround the trunk of the grape plant in use, and a plurality of fertilizing pipes 3 and hole digging nails 4 are arranged on each hole digging and fertilizing frame. After the position is found, the hole digging nails 4 are nailed into the soil around the plant by stepping on the force, and then the drainage switch 10 is opened to inject water-soluble fertilizer, so that the multiple fixed positions around the grapevine are simultaneously and uniformly distributed. The problems of limited coverage and unreasonable nutrient distribution in traditional single-point or multi-point distributed fertilization are overcome, the fertilization accuracy and efficiency are enhanced, and the phenomenon of burning seedlings caused by excessive centralized supply is effectively prevented. During use, the surrounding mouth C surrounds the part of the trunk of the grape plant close to the ground, so that the fertilizing pipes 3 and the hole digging nails 4 are distributed around the trunk of the plant. Preferably, the diameter of the nail tail of the hole digging nail 4 is greater than the diameter of the pipe of the fertilizing pipe 3, so that the diameter of the hole is greater than the diameter of the pipe of the fertilizing pipe 3, preventing hard soil from blocking the drainage hole 5 and causing poor drainage of water-soluble fertilizer. The storage barrel 7 can be preloaded with a certain amount of water-soluble fertilizer, or can be externally connected to a backpack type medicine barrel for filling water-soluble fertilizer.

[0029] Preferably, the drainage pipe 2 is arranged in an arc shape. The arc design allows the fertilizing pipes 3 to be evenly distributed around the trunk of the plant, and the distance between the fertilizing positions and the trunk is approximately the same. The drainage pipe 2 is arranged inclined relative to the horizontal plane, and the end of the drainage pipe 2 connected to the three-way piece 9 is higher than the other end. This design allows the water-soluble fertilizer to be more smoothly distributed to each fertilizing pipe 3 by gravity.

Since the thread direction of the main screw 14 and the slave screw 15 at the end is opposite, the threaded sleeve 1 can be screwed forward or backward, so that the main screw 14 and the slave screw 15 move closer to or farther away from each other, thereby adjusting the distance between the two hole digging and fertilizing frames, and adjusting the distance between the fertilizing positions and the trunk of the plant.

[0032] According to an example of the utility model, the upper end rear side of the bearing frame 1 is provided with a left handle 17, a left pull handle 18 is rotatably installed below the left handle 17, and the left handle 17 and the left pull handle 18 are connected through a reset spring 19.
