The invention discloses a method for breeding aconite which comprises the following steps of: soaking seed with GA3 solution, sowing seeds, managing after sowing, transplanting, and the like. Before the aconite seed is sown, the aconite seed is soaked in a GA3 solution having a concentration of 400mg/L to 1000 mg/L, in order to obviously promote the germination percentage and the germinating energy of the aconite seed, increase the fresh weight of the over-ground part of the aconite seedling, and emerge rapidly and orderly. The growing of the aconite seedling can be boosted and the earthnut diameter can be increased by using a proper sowing and managing method so as to decrease the breeding cost of the aconite and promote the yield of the aconite.
