The invention relates to a method for raising and
transplanting corn seedlings. The method includes fetching
earthworm cast and soil to be used as corn
seedling raising substrates; exposing corn seeds under the sun; soaking the seeds in running clear water;
drying the seeds and waiting for
sowing the seeds; filling the dry substrates in each disc; thoroughly watering the flexible discs in a mist form;
sowing one seed in each hole; stacking the discs in indoor environments to form
germination piles and accelerating
germination in a centralized manner; tightly wrapping the
germination piles by plastic thin films; increasing the temperature; exercising buds and enabling the buds to receive illumination so as to turn green when 80% of seedlings are ejected out of the soil in each disc of each germination
pile; thoroughly watering the seedlings before the seedlings are transplanted;
transplanting the seedlings with the soil. The method has the advantages that shortcomings that built
seedling beds occupy production lands and costs of links for manufacturing the
seedling beds, constructing seedling raising sheds, managing the seedling beds and the like are increased can be overcome; the structures of the seedling raising substrates are improved, effects of robustness of corn root development, high white root proportion and
transplanting viability and good root and soil binding property can be realized by the aid of the
earthworm cast, the emergence rate and the emergence uniformity can be guaranteed, the cost is low, the efficiency is high, the quality of the seedlings is good, and programs are simple.
