Corn seeding technology
In order to solve the shortcomings of corn seed, it is possible to adopt the province's fine seeding technology to solve it. Do a good job of seed treatment, improve germination and seedling emergence rate by sowing seed before sowing, soaking, seed dressing or seed coating and other treatment methods, can increase seed germination potential, increase germination and emergence rate, so as to achieve the premise of saving species, achieve The purpose of Miao Miao Miao. The drying sun seeds can effectively kill germs on the seed surface, promote seed ripening, reduce seed moisture content, enhance seed water absorption, increase seed germination rate by 13% to 20%, and can emerge for 1 day to 2 days earlier. The method of drying seeds is to select sunny days from 10:00 am to 4:00 pm, spread the seeds to the dry mats in sunny spots, turn them upside down, store them in the room at night, avoid moisture, and continuously expose them for 2 days to 3 days to make seeds. Fully dry. Do not spread the seeds on the iron or cement floor to avoid drying the seeds. Soaking seed soaking can stimulate the seed to enhance the new metabolism, increase seed vigor, and the emergence of seeds after sowing is fast and vigorous, with obvious effect of increasing yield. After sowing, soaking in cold water or warm soup the day before sowing. The method of soaking seeds in cold water is to put the seeds in clean water, and the amount of water is suitable for soaking the seeds, and soaking for 12 hours to 24 hours. The soaking method of warm soup is: soaking with warm water of 45°C-55°C for 6 hours - 10 hours. Warm soaking also kills smut, anthracnose, and other pathogens on the surface of the seed, which is better than soaking in cold water. The soaked seeds can be sowed when they are spread in the shade and dried on the surface of the seeds, or after seed dressing. After picking seeds for seed dressing and dressing seed dressings, they have good effects on pest control and preservation of seedlings. With 25% triadimefon wettable powder, 0.2% of the dry seed amount can be used to control corn smut. Use 50% phoxim EC mix, water and seeds in the ratio of 1:100:1000 for seed dressing and mix well for 4 hours to 6 hours. Seed coating can be directly selected for coating seeds where conditions permit, the use of coated seeds can not only control the earthworms, cockroaches, wireworms and other underground pests, but also can control the corn seedlings of aphids, thrips, stem rot, etc., Can also promote plant growth and development, increase production and income. When seed coating, 20% seed coating agent No. 19 can be used, the seed moisture content should be controlled at 12% to 14%, and 1 kg seed coating agent can coat seed 50 kg. To promote seedling transplanting, both provincial and increased production Transplanting corn seedlings is a good measure to save seed and increase yield. With seedling transplanting, 1 kg of selected seed memo can meet the needs of an acre field, which can save 1 kg to 2 kg of seed than general seeding. At the same time, the seedlings transplanted and planted were short-sturdy, with multiple secondary roots, low panicles, drought resistance, and lodging resistance, which were more than 10% higher than those of live summer corn. Seedling time: When the seedling age reached 6-8 leaves, it was transplanted and the seedlings were grown 20 days to 25 days before. The seedlings should be finely screeded and full-grown, and the base fertilizer should be applied. The spacing should be 18 cm to 23 cm and the spacing between 6 cm and 9 cm. The seeds should be sowed. After sowing, the cover soil should be 3 cm to 4 cm. When the seedlings grow two leaves, they combine with Dingmiao to clear the earth. Three days before transplanting, the secondary roots were raised by light irrigation, and the seedlings were raised to protect the secondary roots, so as to ensure that they would quickly grow into robust growth after planting. When planting, the seedlings shall be transplanted separately according to the size and size, and the seedlings shall not be mixed to prevent seedlings from sprouting. It is best to choose cloudy or sunny afternoon transplanting, open the ditch according to the predetermined spacing, with the ditch with the seedlings with transplanting, seedlings close to the ditch after righting the cover soil 3 cm -4 cm, with the plant with watering, the next day Then ditch a ditch, and other water infiltration, along the ditch to recover a standard nitrogen fertilizer 10 kg per acre, and then cover the flat ditch, and timely cultivation of loose soil, promote seedlings early and long hair. According to the seed size classification, the implementation of precision on demand Combine the sun seeds, divided into three grades according to the seed size, one seed at the time of sowing, one for each hole; two seeds for the first hole, two for the second hole, one for the third hole, and two for the fourth hole ... and so forth sowing; seeds of three seeds are sown in two seeds per hole. This sowing can ensure full seedlings, and save about 1 kg of seed per acre. Pay attention to sowing, we must plant seedlings in different stages, do not mix seeding to prevent seedlings from being uneven and seedlings of different sizes.
