Greenhouse seedling raising method of Psammosilene tunicoides seed

The invention discloses a greenhouse seedling raising method of a Psammosilene tunicoides seed, belonging to the technical field of raising the seedling of a plant seed. The method comprises the following steps: raising the seedling of a Psammosilene tunicoides seed in a greenhouse, maintaining the soil temperature at 20+/-2 DEG C in the greenhouse, controlling the soil humidity at 50-65% in the greenhouse in a period from the sowing of the Psammosilene tunicoides seed to the growth of two pairs of euphyllas, controlling the soil humidity at 28-38% in the greenhouse in the growing process of the Psammosilene tunicoides seedling from the growth of two pairs of the euphyllas to the growth of three pairs of the euphyllas, and controlling the soil humidity at 15-30% in the greenhouse in the growing process of the Psammosilene tunicoides seedling from the growth of three pairs of the euphyllas to the outplanting of the seedling. By artificially regulating the soil temperature and the appropriate soil humidity for
