The utility model relates to a cyclic annular fertilizer applicator of electronic ration is transplanted to flue -cured tobacco belongs to the agricultural machinery field, the utility model discloses a ration axle carries out the ration with the cooperation of ration seat with the granule chemical fertilizer in the fertilizer bucket under the drive of micromotor, different growth period at tobacco seedling, can also be through quantitative regulation piece adjustment rate of fertilizer application, granule chemical fertilizer edge unloading pipe after the ration enters into the toper and spills in the dish, the toper is spilt the dish and is spilt the granule chemical fertilizer under the rotation effect around the cyclization shape drops on cave pool xiao miao, play cyclic annular fertilization effect, it can grow downwards to guarantee tobacco seedling's root system, and simultaneously, the electronic quantitative fertilization to every trunk tobacco seedling has also been realized, great reduction worker labor intensity, the efficiency of fertilize is improved, again among the fertilizer application process, go back accessible tapered hood and cover the toper and spill the dish, prevent that the chemical fertilizer from dispersing, causes the waste of chemical fertilizer all around, the utility model discloses simple structure, portable, the practicality is strong, has effectively improved fertilizer application efficiency.
