1, sowing the wrong season. The sowing date can be determined according to the market conditions, which can be broadcast in spring or summer. In order to get the fresh corn ear to market at the wrong time, it can be sowed in stages. The use of mulching or nursery transplants promotes early maturation and can be marketed in advance, thereby increasing economic efficiency.
2, species selection. When buying seeds, it is necessary to pay attention to the number of certifications, and secondly, to the suitability of the varieties. Choose appropriate local environment, purity is not less than 98%, clarity is not less than 98%, germination rate is not less than 85%, growth period is suitable, skin is thin, no slag, good taste, moderate sweetness, high viscosity and high quality and high yield resistance Diseased sweet, sorghum and other corn varieties suitable for fresh food.
3, field management. Most fresh corn (sweet, glutinous, popping, etc.) grains are lean, and their ability to germinate top soil is poor. They should be properly shone, less covered, and seedlings relatively thin. Therefore, soil fertility, non-compacting, and water and fertilizer conservation should be selected. Plots are planted. The crushing and smoothing of the tillage layer is conducive to the smooth germination and emergence of the seeds. It is also conducive to the large-scale propagation of soil microorganisms, accelerates the decomposition of organic matter and minerals, and improves the soil fertility and the ability to adjust the soil temperature. In addition, the fresh corn seedlings are weak in growth, and they should work hard to preserve the seedlings. The seedlings should be top-dressed early and promote early-onset hair growth; strengthen the management of flowering and pollination and fertilizer and water during the grain-filling period; remove the miscellaneous plants and tillers as soon as possible; adopt artificially-assisted pollination; Reduce baldness and improve product quality.
4, strict isolation. When fresh corn is grown, it needs to be isolated from other corn in order to minimize the interference from other corn pollen, otherwise it will lose or weaken its original characteristics, affect quality, and reduce or even lose the value of the commodity. Fresh corn in production must be isolated from other corn planted in the same period by 300 to 400 m; or by 25 to 30 days from the flowering period of other corn varieties; or by using natural barriers such as hills, villages, and forests.
5. Pest control. The grains and plants of fresh corn have high nutrient content and good quality, which can easily lead to the harm of underground pests and corn borer, beetle, aphid and other pests. After the corn ear is damaged, it will seriously affect the quality of its products and market prices. Therefore, early prevention must be prevented early to prevent it. In order to prevent food poisoning, fresh corn should be controlled by biological and biological pesticides after pollination, and chemical pesticides should be avoided or used as much as possible. Never use highly toxic pesticides with long residues.
6, timely harvest. The harvest of fresh corn should be timely harvested according to different needs and market demands in order to ensure its best quality and palatability, and to obtain the highest economic benefits. It should normally be during the milk development period of grain development (about 25 days after pollination), that is, when the filaments become dark, the best period for harvesting.
