Fresh-eating autumn corn is a kind of high-quality and high-efficiency late-autumn crop with wide adaptability, short growth period and rich nutrients, and it is favored by consumers for its fresh fruit ear supply market. The cultivation techniques are as follows: 1. Selection of good varieties: Autumn corn must be selected from hybrids with wide adaptability, strong disease resistance, short growth period, high quality, high yield, good spike appearance, and good fresh-stalk taste. Rugao No.2 and No.7. Timely sowing? Fresh-eating autumn corn is different from fresh spring corn. Due to the high to low temperature during the growing period, the grouting time is longer than that of spring corn, and the temperature requirement is strict. The temperature requirement during the grain filling period of autumn corn is not lower than 20°C. If the temperature is lower than 16°C, the filling will be slow, and if the temperature is lower than 15°C, the grouting will stop. Therefore, it is possible to start sowing in batches in mid-July, at the latest by the end of July, and the fresh ear can be listed in late October. Second, transplanting seedlings? Autumn corn during the sowing season is hot, frequent thunderstorms. In order to increase the seedling emergence rate, transplanting with small seedlings should be adopted. Choose a well-drained nursery bed, where the seedbed is moist and cool, and a layer of wet straw is placed on it to prevent direct sunlight and thunderstorms from hitting the seedbed. After the emergence, the cover was peeled off to promote growth, and the seedlings were transplanted to the field when the seedlings grew to the second leaves. Third, the rational close planting? Fresh autumn corn due to high temperature early reproductive, fertility faster, the same cultivar in the whole growth period than the fresh spring corn shortened 10-15 days, plant short 10 cm, the total number of leaves less 2 tablets. In order to ensure uniform size of fresh fruit ears, increase commercial quality and increase yield and quality, planting 4500-5000 plants per mu is appropriate. Fourth, scientific fertilization? Adhere to the application of base fertilizer, application of phosphorus and potassium fertilizer, early application of Miaofei, discretionary joint fertilizer, re-apply attack manure principles. Basal fertilizer generally applies 1,500 kg of land-fertilizer, 30 kg of phosphate fertilizer, 8 kg of potassium fertilizer, 20 kg of ammonium bicarbonate or 7 kg of urea. When transplanting 500 kg of Mushi rooting. After cultivating and weeding, the seedlings applied 5 kg of urea and phosphate fertilizer to promote early seedling emergence. When jointing, depending on the seedling growth, fertilization is appropriate to promote balanced growth. In the big bell-mouth period, it will be used for attacking manure, applying 50 kg of ammonium bicarbonate or 15-18 kg of urea, applying deep ditching to cover soil, and clearing the soil to protect the seedlings. V. Preventing pests and diseases? Autumn corn is susceptible to locusts and other hazards during its growth period. It is necessary to use high-efficiency, low-toxicity, and no-residue pesticides for prevention and control in a timely manner, and stop using pesticides 7 to 10 days before harvest. Timely harvesting: The general harvest period of autumn corn is preferably 30 to 35 days after pollination. Premature grouting is not sufficient for early harvesting. It is not sufficient for pods, and the yield is low. Source: Sichuan Rural Daily
