In the past two years, fresh corn has been favored by the vast number of consumers in farmers' markets in various places. In many places, farmers are prepared to take advantage of business opportunities to prepare for spring planting in order to increase market revenue. However, for farmers, it is the key to selecting good breeds. Indispensable sowing is essential. The sowing method must be mastered. 1. Variety selection Fresh corn requires good glutinous properties, thin peel, delicate texture, good product traits, and medium-sized ear, suitable for steaming and quick-freezing processing. The fresh corn that is currently sold on the market includes waxy corn, sweet corn, black corn, colored corn, and common corn. The characteristics of the commodity are different, resulting in uneven prices of fresh corn and significant differences in production efficiency. To increase the yield of fresh corn, choosing the right variety of road is the key. Waxy corn is the preferred variety for fresh corn. Waxy corn varieties have the best quality of medium white, and under normal circumstances, the quality of black, purple and red color varieties is relatively poor. Second, the appropriate time sowing open field cultivation, spring sowing suitable sowing time for the ground temperature stability above 10 °C, the best seedling stage after the local late frost period; summer sowing season corn temperature during the filling period of 16 °C or more. Third, isolation and cultivation of fresh corn must be isolated from ordinary corn, to prevent the impact of string quality of fresh corn. When space is isolated, the spacing should be more than 300 meters; when time is separated, sowing time should be more than 15 days. Fourth, soil fertility cultivation of fresh corn should choose fertile soil, high organic matter content, good irrigation and drainage conditions, good soil permeability. In order to improve the quality of fresh corn, it is necessary to apply base fertilizer and increase organic fertilizer. To implement formula fertilization, generally 3000-4000 kg of high-quality farmyard fertilizer and 50 kg of ternary compound fertilizer are applied per acre, and appropriate amounts of zinc, boron and other microelement fertilizers are applied. 5. Manual seeding should be conducted before planting sowing to remove pods, mold grains, broken granules and impurities, and soaking with 0.2% potassium dihydrogen phosphate for 8-12 hours. The sowing method is direct broadcast, with a width of 80 cm, a narrow row of 50 cm, a plant spacing of 25-30 cm, and 3500-4000 plants per acre.
