First, the appropriate time sowing: open field cultivation, spring sowing period is stable in the ground temperature above 10 °C, the best seedling stage in the local after the late frost period; summer sowing season corn temperature during the filling period of 16 °C or more.
II. Isolation: The cultivation of fresh corn must be isolated from ordinary corn to prevent the quality of fresh corn from being affected by the skewer. Space separation distance should be more than 300 meters, time isolation, sowing time interval should be more than 15 days.
Third, the site preparation of fertilization: should choose fertile soil, high organic matter content, drainage and irrigation conditions are good, good soil permeability is best. In order to improve the quality of fresh corn, soil preparation should be applied at the same time as basic fertilizer, organic fertilizer, and fertilizer application. Mushi 3000-4000 kg high-quality farmyard fertilizer and 50 kg ternary compound fertilizer should be applied, and appropriate amounts of zinc, boron and other micronutrients should be applied. .
Fourth, sowing: artificial selection before sowing, remove pods, mold, broken particles and impurities, and then soaked with 0.2% potassium dihydrogen phosphate solution 8-2 hours. The sowing method was direct seeding, wide and narrow row planting, with a width of 80 centimeters, a narrow row of 50 centimeters, plant spacing of 25-30 centimeters, and 3500-4,000 acres planted.
Fifth, field management: 1, remove the childbirth. Due to the characteristics of its own varieties and the basal fertilizer during planting, fresh corn has more tillers, and it is necessary to remove tillers at the seedling stage in time. 2, stay double ear. Fresh corn generally has multiple panicles. To improve the commercial character of the ear, each plant has a maximum of 2 ears, and the remaining ears are removed as soon as possible. 3, top dressing. Dressing should be based on seedlings, in 12-14 leaves, acres of topdressing 10-15 kg of urea. 4, pest control. Fresh corn generally has high sugar content, good quality, and serious corn borer damage. It is controlled by Bt bio-particle pesticides or Batadan soluble powder in large bell mouths, and the use of highly toxic residues with a residual period of 20 days or more is strictly prohibited. pesticide.
6. Harvest: Fresh corn is harvested due to the tender ear, harvesting is very important, premature harvesting, lack of dry matter and various nutrients, low nutritional value, too late harvest, epidermis becomes hard, and taste changes. difference. The suitable period for collection is 20-23 days after pollination, and the varieties differ slightly. 20 days after pollination began to check, so that appropriate harvest.
VII. Postharvest treatment: Fresh corn is mainly sold with fresh panicles. It is best to sell on the same day of the day of the day of harvest. For long-distance sales, certain freshness measures must be taken to prevent corn ear from depleting its nutrient components due to respiration. Moisture, causing a drop in freshness and quality.
