At the same time, this technology is also convenient for integrated irrigation of water and fertilizer, and has a good effect of saving water and fertilizer. Shallow buried drip irrigation usually consists of drip irrigation capillary tubes and main pipelines. In actual use, the solubility of fertilizers at the water inlet main pipeline is poor, and the mixing uniformity with the water body is not high, which not only affects the drip irrigation effect of fertilizers, but also easily causes the blockage of drip irrigation heads.

9. A method for using a fertilization device based on shallow buried drip irrigation of alfalfa, characterized in that: The fertilization device based on shallow buried drip irrigation of alfalfa as claimed in claim 8 is used in the following steps: Step 1: water is input from the water inlet pipe (15), and the conical filter (19) filters the water. Impurities in the water are accumulated around the conical filter (19), thereby maintaining the fluidity and filtering effect of the middle part of the conical filter (19). In the process of falling into the filter box (7), the spiral blade (16) is driven to rotate at the same time. The spiral blade (16) then drives the connecting rod (17) and the scraping rod (18) to rotate. The scraping rod (18) is used to assist in scraping the conical filter (19), thereby reducing the clogging of the conical filter (19); Step 2: The water is then transported from the connecting pipe (20) to the processing box (5), and the fertilizer is input from the feeding cylinder (10) into the processing box (5). The driving motor (81) is started to work, and the driving motor (81) drives the rotating shaft (82) and the breaking rod (83) to rotate. The breaking rod (83) breaks the fertilizer, and the horizontal plate (84) and the limit plate (812) rotate and stir. The horizontal plate (84) and the vertical rod (88) are subjected to centrifugal force, and the vertical rod (88) drives the slider (87) to slide on the fixed rod (86). The slider (87) stretches the spring (89), and the sealing film layer (810) plays a sealing role. The vertical rod (88) moves to drive the side rod (811) to scrape the inner wall of the processing box (5) to reduce the adhesion of the fertilizer. Step 3: The rotation of the horizontal plate (84) drives the inner rod (814) to rotate, and the inner rod (814) drives the contact rod (820) to rotate. The contact rod (820) is blocked by the blocking block (819) and acts on the torsion spring (817) until the contact rod (820) is separated from the blocking block (819). The elastic force of the torsion spring (817) is reset, thereby driving the inner rod (814) to rotate, so that the inner rod (814) revolves and rotates at the same time, thereby improving the stirring range and stirring effect; Step 4: By opening valve 1 (11), valve 2 (12) and valve 3 (13), the mixed water and fertilizer are transported to the branched main pipe part (2) through the main pipe part (1), and then transported to the branched branch pipe part (3) and capillary pipe part (4) through the main pipe part (2). The water and fertilizer will flow into the connecting hole 1 (95), and then flow into the connecting hole 2 (96) through the regulating hole (97), and finally drip out from the drip tube (94) for irrigation. By rotating the drip tube (94), the drip tube (94) drives the rotating ball (93) to rotate, and then adjusts the regulating holes (97) with different apertures to communicate with the connecting hole 1 (95) and the drip tube (94), so as to facilitate the adjustment of the drip irrigation water volume.
