Management technology of maize planting

The planting of corn is to accelerate germination and seed dressing, and the management technology pays attention to seedling management.

1. Planting: When planting corn, select seeds with full grains and no pests and put them into clear water, then remove the withered seeds floating on the water surface, and then put the corn seeds under the water surface into pesticides and stir them to eliminate germs on the surface of the seeds and reduce the probability of corn infection.

2, management: seedling management, 4-5 unfolded leaves or 7-8 visible leaves before jointing. Dark green leaves, broad and strong leaves, suitable for squatting. Keep the soil dry and wet, and the soil moisture accounts for 60% of the field moisture, so as to promote the root system to develop and form an expanded root system, take root deeply, achieve the purpose of squatting and strengthening seedlings, and be conducive to deep water absorption, drought resistance, seedling protection and bumper harvest in the middle and late stages.

Fertilization method of corn

Corn is suitable for growing in loose, breathable and humus-rich soil. When planting corn, we should cultivate deeply and intensively to make the soil soft, then sprinkle the decomposed cake fertilizer and plant ash on the soil surface once, and turn the soil again to make the fertilizer uniform, which is beneficial to the vigorous growth of corn.

The application of corn seed fertilizer is mainly to meet the demand for nutrients in the early growth stage of corn, and it is mainly used in plots with insufficient base fertilizer. In the field where zinc fertilizer is not applied in the base fertilizer, seeds can be mixed with zinc fertilizer, and 6-8 grams of zinc sulfate can be added to each kilogram of seeds. When using chemical fertilizer as seed fertilizer, the dosage should not be too large, so as not to affect seed germination. Fertilizer should be applied next to the seeds, 4-5 cm away from the seeds, which can be hole-shaped or strip-shaped.
