Factory based rice seedling cultivation

Rice factory seedling cultivation technology is a large-scale seedling cultivation method based on precision and semi precision sowing technology, using mechanized production lines for sowing, and adopting greenhouse or field centralized cultivation. It is an emerging agricultural cost saving and efficiency increasing technology. Unit cost reduction20%Above, the seedling rate reaches90%above. It has the advantages of high technological content, large production scale, low seedling raising cost, good quality, and saving seeds and labor. The price of rice factory grown seedlings is about30first/Mu (not suitable for seeds) is highly welcomed by farmers.
1、 Selection of sowing production line. At present, the first mature production line in China is jointly developed by Jiangsu Agricultural Machinery Promotion Station and Jiangsu Yunma Agricultural Machinery Manufacturing Co., Ltd2BLY-280B seedling and sowing machine (assembly line)The seedling raising and sowing assembly line adopts a patented spiral seeder technology, which can adapt to the seedling raising and sowing of all rice varieties. High seeding accuracy, low hole rate, and uniformity achieved90%Above, the bottom soil, sowing, covering soil, and spraying water are all completed in one go, resulting in a shift yield5000－6000Plate, mechanized transplanting requires about per acre of seedling field25Standard seedlings on both sides of the plate, machine unit price2About ten thousand yuan. At present, automatic loading machines, automatic closing machines, soil crushers, loading machines, de awning machines, dewatering machines, and power conveyor lines are also produced for factory seedling cultivation, greatly reducing labor and meeting all the needs of factory seedling cultivation.

2、 The choice of paddy fields. Concentrated seedling cultivation can be carried out through greenhouse cultivation, field cultivation, or dry cultivation. For field seedling cultivation, it is necessary to choose sandy fields that are flat, fertile, easy to irrigate, and have windward and sunny conditions to facilitate seedling growth and seedling emergence during transplantation. The paddy field should have a good box ditch and a surrounding ditch, and the water in the box area should be drained. After drying and tightening the skin, the seedling tray can be placed. The seedbed for dry seedling cultivation should be chosen to be windward and sunny, fertile and loose. Flat land or dry or dusk fields should be plowed and finely leveled in separate compartments. After that, decomposed farmyard manure should be applied to flatten the soil and make it slurry. Then, a layer of thin mud should be applied to smooth it out before laying the plate. Mu used seedbed7-8square meter.

3、 Seed processing. Select high-quality rice seeds, soak and disinfect them after cleaning, and then36-38℃ chest rupture promotes germination12-15Hour, sprout growth0.5mmLeft and right (resembling ant eggs). After germination, the rice seeds can be sown on the sowing production line after drying the water (the air suction seeder must first remove the awning of the rice seeds). 4、 Nutrient soil preparation.1Take sticky mature soil and add cooked manure per acre5Kg, or a small amount of fecal water mixed with superphosphate0.5Mix kilograms evenly. Use dexamethasone per acre6-8After disinfecting with diluted water, let it ferment for one month. likePHValue greater than7If it is alkaline, it needs to be treated with acid adjustment (added)70－100Ke fine sulfur powder can reducePHAfter being air dried, crushed, and sieved, it can be machine sown on the sowing production line. Nutritionally, the moisture content must be less than3%.2Alternatively, sticky mature soil can be used. After air drying, powdering, and sieving, each100Kilogram nutrient soil with seedling strengthening agent2Kilograms are directly machine sown on the sowing production line, using soil per acre40-50kg .
