Method for raising and transplanting corn seedlings

Abstract

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.

Description

technical field [0001] The invention relates to agricultural cultivation techniques, in particular to a corn seedling raising and transplanting method. Background technique [0002] Prior to the present invention, existing corn seedlings had the disadvantages of maintaining root system activity and low transplant survival rate in terms of seedling substrates, and at the same time, it was necessary to establish seedbeds for seedling cultivation. On the one hand, the establishment of seedbeds needs to occupy a certain production field, and on the other hand, it needs to increase the cost of the production of seedbeds, the construction of seedling sheds, and the management of seedbeds. Contents of the invention [0003] The purpose of the present invention is just to overcome above-mentioned defect, develops a kind of corn seedling raising and transplanting method. [0004] Technical scheme of the present invention is: [0005] A method for transplanting corn seedlings, its...

[0002] Before the present invention, the existing corn seedlings had the disadvantages of maintaining root system vitality and transplanting survival rate in the aspect of seedling raising substrates, and at the same time, it was necessary to establish seedbeds for raising seedlings.

On the one hand, the establishment of seedbeds needs to occupy a certain production field, on the other hand, it will increase the cost of seedbed production, seedling shed construction, and seedbed management.
