Full-seedling and strong-plant cultivation method for corn
InactiveCN105917930ARealize full seedlingIncrease moisture contentFertilising methodsPlant cultivationBiotechnologyPlastic mulch
The invention belongs to the technical field of agricultural cultivation and discloses a full-seedling and strong-plant cultivation method for corn. The cultivation method comprises steps as follows: seed selection and coating, furrowing and bedding, returning of straw to field, layered fertilization, precision sowing, chemical weeding and film mulching, final singling at suitable time and field management. According to the method, furrows are dug between corn sowing rows in a un-fallowing and no-tillage ridged field, bottom layers of dressing furrows are covered with chopped straw, the straw can prevent upper-layer fertilizer from leaking down, the decomposed straw becomes fertilizer and can be absorbed and used by corn roots, isolation is performed with loam for layered fertilization, and one-time fertilization can be used by the corn in the whole growth period; holes are dug in rows in a sowing region, two healthy, full and vigorous corn seeds are sown in each hole for final singling at suitable time; the fertilization region is covered with a mulch after chemical weeding, and the temperature under the mulch is higher than the subsurface temperature of the corn sowing region, so that fertilizer and water under the mulch slowly permeate soil in the corn sowing region, full-seedling, strong-seedling and strong-strain of the corn are realized, and the basis for increasing the corn yield is consolidated.
