Xinping County has abundant winter leisure land resources, and the hot dam area along the Red River Valley has a warm winter climate and is suitable for growing autumn and winter vegetables. In October 2007, Mosha Town cooperated with Yuxi Weite Biotechnology Co., Ltd. to introduce the United States super sweet corn suitable for planting, and achieved success. One mu can produce fresh glutinous rice 1032kg, and the output value reaches 1375 yuan, in order to accelerate the promotion of American super sweet. Maize, according to the growth requirements of sweet corn in Xinping County, proposed technical measures suitable for the cultivation of sweet corn in our county. American Super Sweet Corn This variety is introduced in the United States and has the characteristics of excellent quality, good taste and high yield. Corn is sweet as milk and can be eaten raw. The most important one is used for fresh corn cob frozen packaging export. This variety is plant dwarf variety, the general plant height is 130-150cm, the growth period can be harvested from 100 to 110 days, and the ceiling is started 20 to 25 days after transplanting. It has strong tillering, generally in the third true leaf. At the beginning of the heading, if the fertilizer and water management conditions are good, you can also pump double sputum, single scorpion weight 300g, scorpion length 20cm, grain golden yellow, solid soluble substances account for 34% of fresh corn. First, the field selection The United States super-sweet corn is a large-water and large-fertilizer crop with strong fertility. It is generally suitable to use rice or vegetable fields with good fertilizer and water conditions. The dry mountain is not suitable for sweet corn, and the soil is loose and fertile. Drainage and irrigation is convenient, the shade is sunny, and the PH value is between 5.5 and 6.5. Sweet corn can also be planted in sugarcane fields, with good growth, or sweet corn and other short bean crops are also ideal. Second, seedling transplanting Generally, it is ideal to use seedlings for nutrient tray transplanting. The seedlings are neat and tidy, and the corn is fast-growing. The seed of each field requires 650g of seeds and 40-45 pieces of 100-hole plastic. The nursery site is close to the fixed field, which is conducive to transplanting. In September, or according to the crop season arrangement and the company's product launch time requirements to determine the nursery time, seedling age 20 to 25 days (three leaves and one heart period) can be transplanted. Specific seedling methods: 1. Seed treatment. Dry the selected seeds for 4 to 6 hours, soak them in water for 2 to 3 hours, remove the water control, and break the seeds to sleep. 2. Preparation of nutrient soil. It is prepared by using clay loam and sifted farmyard manure in a ratio of 7:3. Each 100kg of nutrient soil is added with 3kg of calcium or ternary compound fertilizer, and 100g of wormwood is evenly mixed and the membrane is stacked. 3, seedbed soil preparation. Press 120cm to open the sorghum, level the ground, arrange the seedlings neatly, and then sift the nutritious soil on the nutrition plate and pour it. 4, a variety. Put one seed per hole, and it is better to use seeds without revealing soil. After the point, spread a thin layer of nutritious fine soil, pour the bottom water to promote seed germination, sow the enamel arch cover film, and increase the temperature and humidity in the small arch shed. . The periphery is sealed with a plastic film to prevent rodents. 5, seedling management: pay attention to water and humidity during the seedbed, keep the soil moist, 5-7 days after sowing, break the belly and emerge, timely watering, such as weak seedlings can properly pour the manure or apply a small amount of urea, 3 leaves 1 heart period Seedling days can be unearthed transplanted in about 20 days. Third, Daejeon transplanting The sweet corn planting fields in Xinping County are more suitable for winter leisure fields and post-smoke fields. The field work for the whole field should be completed during the nursery period, that is, immediately after the harvest of the former crops, the hoes are controlled and the concrete methods are: 1. Standardize the opening. According to 1 meter opening, the ditch is 20cm, the width of the noodle is 80cm, the center of the sputum is shallowly open, and the fertilization ditch is used in the center of the sputum. The farmer's fertilizer is 1000-2000kg, and the farmhouse 1 (corn special) is 60-80kg. 2, the plastic film covered. Before the film is covered, we use 41% Yu Nongsi emulsifiable concentrate to spray 100g per acre. This is to kill the grass, and then to implement the method of rupturing the membrane after the first cover film. The acre is 90cm wide agricultural film 5kg. The surrounding is compacted and sealed. 3, wide and narrow row orientation (true leaf direction one to) transplanting. The standard cultivation field is ideal for wide and narrow row cultivation. The sugarcane field can be directly planted on the alfalfa surface. The planting size is (80+40)/2×20cm, and about 4300 plants are planted in acre. Root water. 4. Time selection. When the seedling age is three-leaf one-hearted period, it is transplanted. According to the company's acquisition requirements, it is better to implement a uniform planting period, which is generally carried out in the evening. Fourth, field management 1. Fertilizer and water management: Moisture should be kept moist by soil. It should not be poured in the early stage. In the middle and late stages, if it is dry, it can be filled with water. Applying the seedling fertilizer on the basis of applying the base fertilizer in a timely manner (10 days after planting can be applied), applying 5 kg of urea to the seedlings, applying the panicle fertilizer, and applying the spray fertilizer to each mu of the large trumpet period. Apply 4kg to water, and spray the prodamine (high potassium) 600 times solution to promote plant growth and booting differentiation. 2, Chatang fills the gap. Generally, only a single plant is planted. If there is a dead seedling, the seedling should be replenished in time to ensure that the basic number of seedlings is the basis for obtaining high yield. 3, in addition to 蘖定苞: US super sweet corn is very strong, timely stripping of invalid tillers, reducing nutrient consumption, leaving one plant per plant, leaving the first raft is appropriate. 4. Follow the biogas slurry. In the seedling stage, jointing stage, booting stage, and filling stage, it is better to properly apply the biogas slurry according to the growth of the corn. Apply 250kg of biogas slurry per mu, and master the principle of less before and after, and pour it in the fertilization ditch. 5, artificially assisted pollination; flowering period 9 to 11 am, using shaking plants or pulling the plant with a rope to stimulate the plant to facilitate pollination, to achieve the purpose of pollination. Manual assisted pollination should be carried out under the guidance of a technician, otherwise it would be counterproductive. V. Pest Control According to planting conditions, sweet corn often has corn borer, aphid, and red spot disease. 1, corn glutinous rice: use 5% inhibition Taibao 70 ~ 90ml / acre or 48% lesbian emulsifiable oil 50 ~ 80ml / a total of water spray, spray in the morning is appropriate. 2, aphids and cabbage caterpillars: use green waves (biological pesticides) 800 ~ 1000 times liquid spray, (take 50% of smallpox) spray once every 10 days. 3, red spot disease: with Jin Lux 5000 times liquid spray control. Sixth, timely harvest At the end of the second pollination, the corn is filled into the grain filling stage. Generally, it can be harvested 100~110 days after planting. When the corn silk is blackened twice, the blasting of the head is full of semi-conical shape, which is the best picking period of the product. Product acquisition standards: One type of product has a single ear weight of 300g or more, the second type of product has a single ear weight of 200-300g, and a single ear weight of 200g or less is a substandard product. Picking method: Generally, the day of picking and transporting on the same day, the processing and freezing will be carried out. When picking, the whole stalk will be removed, the stalks will be cut off, and the products will be sold according to the product purchase level. The plants can be used as fresh feed.
