As a preferred embodiment of the present invention, as shown in fig. 4-5, the soil covering portion includes a connecting portion 224, a vertical partition 225 and a slant scraper 226, wherein the connecting portion 224 is connected to the second connecting lug 213, the connecting portion 224 may be an elastic rod or a fourth hydraulic cylinder, a slant lower end of the connecting portion 224 is connected to the vertical partition 225 or the slant scraper 226, the vertical partition 225 is disposed on one side of the trench close to the crop, a front end of the slant scraper 226 is located on the other side of the trench, and a rear end of the slant scraper 226 is gradually close to the vertical partition 225 and connected to a rear end of the vertical partition 225, a soil gathering port 227 is formed between the vertical partition 225 and the slant scraper 226, soil turned up by the one-way ditching wheel gradually enters the soil gathering port 227 during the traveling of the agricultural machine, the soil gathering port 227 refills the gathered soil into the trench, and the vertical partition 225 always keeps close to the crop, and the stalk alone does not directly contact the crop. The connecting portion 224 of this embodiment is an elastic rod or a fourth hydraulic cylinder, and generally adopts an elastic rod, so that after the fixing ring body 204 of the angle adjusting mechanism adjustment layer deep fertilization unit 200 rotates by a certain angle, because the lower end of the soil covering portion is always in contact with the ground, a certain amount of elastic deformation occurs to the elastic rod, and the soil covering portion is ensured to backfill the soil turned over above the ground into the groove.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
