Before sowing corn, first remove the severely damaged, extremely large or extremely small, thin grains and impurities, and select full, bright-colored grains. Uncoated seeds are easier to manually select. The shape of the seeds of each variety is different, for example, some seeds are round grains, and some seeds are long grains. The shape does not determine the speed of germination and the strength of the soil. Some seeds may have black navel and wrinkles. Or purple thread, these have nothing to do with the quality of the seeds, the selected seeds germinate more evenly and emerge more neatly. The second is sun drying. Sun drying is generally carried out 10 to 15 days before sowing. It should be carried out on a sunny day from 9 am to 4 pm. The seeds should be evenly placed on the balcony and window sill. Large quantities can be spread on the drying ground (not directly Asphalt pavement, cement floor and iron plate to prevent excessive temperature from scalding seeds), the thickness is preferably 5-10 cm, it is often flipped during the day, piled up at night and covered, usually in direct sunlight for 2 to 3 days.

Drying corn before sowing is a good way to increase production without increasing costs. There are three benefits: First, it can use solar ultraviolet rays to kill pathogenic spores that adhere to seeds, and prevent and reduce silk caused by seeds. Diseases such as smut. The second is to reduce the water content of the seeds, so that their water absorption capacity is enhanced. After sowing, they can quickly absorb the water in the soil and germinate quickly, and the seedlings will emerge. The third is to break the dormancy by drying seeds, enhance the activity of enzymes, and improve the germination potential and germination rate of seeds.
