Beet field drip irrigation fertilization device

The invention provides a beet field drip irrigation fertilization device, and relates to the field of beet field drip irrigation fertilization. A mixing structure is rotationally arranged in the water storage tank; a filtering assembly is fixedly arranged on the outer side of the bottom of the water storage tank, and an auxiliary structure is fixedly arranged on the outer side of the filtering assembly; a supporting mechanism is fixedly arranged on the outer side of the auxiliary structure, a fixing assembly is fixedly arranged at the bottom of the supporting mechanism, through the mixing structure, the supporting mechanism and the fixing assembly, impurities on the surface of the filter screen can be continuously cleaned, and the phenomenon that the filter screen is blocked can be effectively prevented; the drip irrigation pipe can be effectively fixed, so that the phenomenon that the drip irrigation head is far away from the root of the beet due to local displacement of the drip irrigation pipe is prevented
