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. Its cultivation techniques are as follows: First, selection of good varieties of autumn corn must be selected for wide variety of adaptability, strong disease resistance, short growth period, high-quality and high yield, ear-shaped appearance, fresh fruit and good taste good hybrid ear. Rugao No.2 and No.7. Timely sowing of fresh and fresh autumn corn differs from that of 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 requirements are 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, seedlings transplanted during the sowing of autumn corn is a hot weather, 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 dense planting fresh autumn corn due to high temperature early reproductive, fertility fast, the same species than the whole growth period of 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, increase the application of phosphorus and potassium fertilizer, early application of Miaofei, discretionary application of joint fertilizer, the principle of re-appropriation attack manure. 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. Prevention and treatment of diseases and diseases During the growth period of autumn corn, they are vulnerable to aphids and other hazards. To control them in time, use high-efficiency, low-toxicity, and no residual pesticides, and stop using pesticides 7-10 days before harvesting. It is appropriate to harvest the harvest time of the general autumn corn at 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. It is knitted with 100% Kevlar fiber, and the palm, fingers and fingertips are made of pure cowhide material for lamination and reinforcement. Anti-knock and bump design, with reflective strips on the back of the hand and wrist. The palm and tiger's mouth has been thickened, and the wrist of the glove is provided with Velcro and buckles, which can be adjusted by themselves. The overall color of the glove is orange (similar to the color of the rescue suit), and the glove has good air permeability, elasticity and durability. Abrasiveness. Kevlar fiber fabric can be flame retardant, the afterburning time is less than or equal to 2s, and it does not melt or drip. This glove is especially suitable for firefighters' rescue operations, especially in harsh conditions such as bare-hand excavation.
