The invention discloses an automated accurate variable-control fertilizer supplement and applying device used in drop irrigation, which includes a fertilizer supplement box structure, a fertilizer supplement conveying apparatus, a fertilizer water control device and a PLC integrated system. The fertilizer supplement box structure is connected to the fertilizer supplement conveying apparatus. Solid fertilizers are conveyed to the fertilizer water control device through the fertilizer supplement conveying apparatus. The fertilizer water control device and the fertilizer supplement conveying apparatus are both controlled by the PLC integrated system. Area of crop requiring drop irrigation and fertilization, application amount of the solid fertilizers and irrigation and fertilization time are inputted through an operation interface of the PLC integrated system, thereby ensuring the times of fertilizer supplement and applying, the amount of each time of fertilizer supplement and applying, fertilizer supplement time and single-time fertilization time. By means of PLC integrated control system, fertilization amount is ensured through growth situation of crops in fields. Fertilization amount, fertilization area and fertilization time are inputted into the PLC integrated system, thereby achieving accurate variable-control fertilizer supplement and applying.
