[0026] See Figure 6 And 7 Second force pipe 24 is fixedly connected with ladder pipe 18;Ladder pipe 18 is slidably inserted with ladder shaft 20;Second elastic member 21 is sleeved on ladder shaft 20;The upper end of ladder shaft 20 is fixedly connected with movable baffle 17;Multiple drainage grooves 19 are set in movable baffle 17;Movable baffle 17 is fixedly connected with traction rope 16;The upper end of traction rope 16 is fixedly connected with hand pull plate 15, by holding palm and thumb hold cover 8, then finger hooks hand pull plate 15, by finger hooking hand pull plate 15, traction rope 16, movable baffle 17 and ladder shaft 20 can be moved upwards, so that drainage groove 19 is communicated with the passageway in ladder pipe 18, at this time fertilizer can pass through drainage groove 19 and ladder pipe 18, then enter spade frame 4 then along second communication groove 5 into soil, then finger releases hand pull plate 15, movable baffle 17 is restored to block ladder pipe 18 to prevent fertilizer from descending under the elasticity of second elastic member 21, then wait for next time soil expander 1 and spade frame 4 are inserted into soil deep place and fertilized again.

[0027] See Figure 3The upper end of the second power-adding tube 24 is connected to and fixedly connected to the gripping tube 25; the upper end of the first power-adding tube 6 is fixedly connected to the gripping cover 8; a limiting cover 9 is detachably fixedly connected to the gripping cover 8; a closing baffle 10 is slidably inserted between the limiting cover 9 and the gripping cover 8; a first elastic element 11 is sleeved on the closing baffle 10; a limiting baffle 12 is fixedly connected to the end of the closing baffle 10; the limiting cover 9 and the gripping cover 8 are connected to the first power-adding tube 6, which has a feeding trough 7. The feeding trough 7 can pour fertilizer from the outside into the first power-adding tube 6 for storage. Then, under the elasticity of the first elastic element 11, the closing baffle 10 can always block the feeding trough 7. When it is necessary to expose the feeding trough 7, the limiting baffle 12 is pulled to take the closing baffle 10 away from the feeding trough 7, so that fertilizer can be poured in. When no fertilizer is being poured in, the fertilizer in the first power-adding tube 6 is sealed, so that there will be no leakage when the fertilizer applicator is tilted.

[0028] See Figure 7 The traction rope 16 is slidably inserted into the wall of the first power-adding tube 6, allowing for multiple positions of the traction rope 16 besides the opening at the upper end of the first power-adding tube 6, thus not affecting the placement of fertilizer.

By rotating the first fastener 14 in both directions, the position of the first force-adding tube 6 on the first force-adding tube 6 can be changed and fixed, thereby adjusting the lowest position of the hand pull plate 15, which is convenient to adapt to different finger lengths. Thus, during the fertilization process, the height and time of the lifting of the movable baffle 17 at the lower end of the traction rope 16 can be easily controlled by hooking the hand pull plate 15 with the fingers, thereby controlling the volume of fertilizer discharged. It can be precisely adjusted as needed.

[0030] See Figure 2 A limiting frame 22 is fitted onto the soil expansion frame 1; the limiting frame 22 has a hole and a threaded connection to a third fastener 23. By rotating the third fastener 23 in both directions, the height of the limiting frame 22 on the soil expansion frame 1 can be changed and fixed, thereby limiting the maximum opening angle between the soil expansion frame 1 and the soil shovel frame 4, thus satisfying the size of the soil gap after fertilization, and thus meeting different underground fertilization requirements.
