First, appropriate early broadcast. Appropriate early sowing can extend the period of vegetative growth, increase the accumulation of nutrients, and can naturally sprout seedlings to avoid leggy. When the temperature is stable above 10°C, it can be sown. Sowing time is around the chill, that is, in mid-January and late. If covered with a plastic film, it can be properly advanced. Second, a reasonable density. The sweet corn and sweet waxy corn, which are mainly grown and sold for fresh sticks, require high yields, good appearance, long and large spikes, full grain, and little baldness. This kind of product is easily welcomed by the masses and its price is higher. Therefore, in the planting specifications should not be too dense, generally 3700-4300 per acre. In terms of planting methods, the size and behavior are good, with a large row spacing of 70 cm, a small row spacing of 40 cm, a plant spacing of 28-30 cm, and a hole seeding of 2-3 seeds. Seeds need to be sown before planting for 2-3 hours in order to increase the seed germination potential, then soak seeds for 8-10 hours, then dry and then sowing. When sowing, it is best to use carbofuran seed dressing, the ratio of its amount to the seed weight is 1:5, can be combined with the control of tigers. Third, check seedlings fill deficiency. Timely inspection of seedlings needs to be completed before the 3 leaves. If the lack of seedlings is not too serious, large seedlings can be transplanted with soil and strong seedlings can make up for deficiencies. Soil replacement can increase the survival rate and avoid man-made three types of seedlings. Fourth, scientific fertilization. When sowing, Mushi compound fertilizer 30-40 kg, the fertilizer should be applied between two or two corn, the depth of more than 10 cm, after the application cover soil. In the 3-leaf stage, one can dilute the faecal water, and 1500-2000 kg per mu. After 5 leaves of Dingmiao, look at the amount of basal fertilizer and the growth of corn and other conditions, appropriate topdressing once attack Miao Fei, general Mushi compound fertilizer 20-30 grams. After the application, note that the earth is slightly thinner. Jointing period, appropriate amount of chase culm fertilizer, can make plants robust, strong, but pay attention to nitrogen, phosphorus, potassium, can not be partial nitrogen fertilizer to avoid leggy. Mushi urea generally 8-10 kg, phosphate fertilizer 10 kg, potassium chloride 5 kg, after the application of soil cover. About 10 days before tasselling, fertilization should be heavy. Generally, Urea is applied with 15-20 kg of urea, 10 kg of superphosphate, and 8-10 kg of potassium chloride. Shi Houpei slightly thicker. Corn pollination results in real time. If corn leaves are light, it needs to be supplemented with grain fertilizer. Generally urea 5-8 kg. Fifth, pay attention to irrigation and drainage. There is more rain in the spring and drainage ditch must be opened to prevent water accumulation. If the weather is dry and the leaves are curled, timely watering or horse watering should be provided. Six, prevention and treatment of pests and rats. Maize diseases mainly include large and small spot diseases and sheath blight, and rust occurs in some places. According to the author's experience, 200 ml of Kefuling and 2 packets of Jinggangmycin powder are sprayed with good results. The prevention of diseases is the mainstay. During the jointing period, both the application of pesticides before and after tasseling are required. Insect pests include corn borers, aphids, and floorworms. After emergence, 200 grams of dipterex were used to spray the seedlings to prevent the ground tiger; corn borer was sprayed with methamidophos, 200 ml of mu was used; During the big bell mouth period, with or without insect pests, methamidophos must be sprayed once and the heroine mixes the liquid once. The liquid medicine should be sprayed on the bell mouth. Rat poisoning is a major hazard to spring corn, even causing particles to fail. Rat killing methods include killing and electrocuting. Drug killing should be carried out before emergence and before tasselling. When the pollination is solid, it is no use to put any poison bait in the sweet corn field, and only electric cats can be used to kill it. Seventh, assisted increase measures. Before maize loose powder, remove 1/2-1/3 of the tassels, can be emasculated by interlacing or septa, and artificially assisted pollination by shaking method, the effect of increasing production is obvious. When the corn filaments wither, the mu will use ―9-20′′ 1.5-2 grams to sneeze or apply water to the water, so that the ear can grow and the grain can be full.
