A method for efficient breeding of maca seedlings

Abstract

The invention belongs to the technical field of plant breeding and particularly relates to an efficient breeding method for maca seedlings. The method is used for solving the technical problems of the existing maca reproduction technologies that the yield of seedling raising is low, the quality is poor, and labor and time are consumed. The technical scheme of the invention is as follows: the efficient breeding method for the maca seedlings comprises the following steps: (a) carrying out seed treatment; (b) preparing nutritional soil; (c) carrying out sowing; (d) carrying out seedling raising management; and (e) carrying out seedling hardening. The method can be applied to the breeding of the maca seedlings, the germination accelerating speed of seeds is high, the emergence of seedlings is even, and the rate of emergence is high; the density of sowing and the quality and yield of the seedlings are greatly improved; the cycle of seedling raising is shortened, the phenology and season of cultivation of the seedlings are controllable, and the survival rate of cultivation is high; and the input-output ratio of seedling raising is high, and the benefit is remarkable.
