The 2BLY-280B seedling and sowing machine (assembly line)  was jointly developed by the Nanjing Agricultural Mechanization Research Institute of the Ministry of Agriculture, Jiangsu Agricultural Machinery Technology Promotion Station, and our company. This product is an efficient automated tray seedling and sowing equipment that integrates functions such as soil laying, watering, sowing, and covering. It can complete all production processes of rice tray seedling and sowing in one go.

The product adopts the technology of spiral seeding , which changes the traditional linear seeding to spiral seeding. It achieves spiral alternating filling and seeding, greatly improving sowing uniformity. It has the advantages of convenient sowing rate adjustment, small sowing rate precision and high sowing uniformity, and is widely used in the seedling cultivation and sowing of conventional rice, hybrid rice, and super rice. This product has now passed the ministerial level scientific and its excellent performance has been unanimously praised by the attending experts. The appraisal believes that this achievement meets the seedling and sowing requirements of hybrid rice and conventional rice, filling the gap in the hybrid rice disc seedling and sowing machine, and the overall technical level ranks among the domestic level.

The 2BLY-280B seedling and sowing machine (assembly line) is a new and practical factory seedling and sowing equipment, which is a key technical equipment for transplanting and seedling cultivation. Further expanding the industrial production of this product and strengthening its promotion and application can not only save costs and increase efficiency, increase production and income, but also enhance the competitiveness of domestic precision seedling equipment, improve the mechanization level of China's planting industry, promote agricultural industrial structure adjustment, and ensure food safety and effective supply, which has important significance.

Technical specifications and parameters

Outer packaging size (cardboard box)

Length * width * height: 2060mm * 600mm * 560mm

Rice production machinery and chemical plant seedling configuration standards:

If the seedling greenhouse is built according to the standard of 30 meters in length, 6 meters in width, and 2.5 meters in height:

Each shed can provide the standardized and standardized amount of seedlings for transplanting in a 30 acre seedling field.

If standard rice trays (length 580mm * width 280mm) are used, 22-25 standard rice trays are required per acre of land.

Industrialized rice seedling cultivation

The 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 centralized cultivation in greenhouses or fields. It is an emerging agricultural cost saving and efficiency increasing technology. The Unit cost is reduced by more than 20%, and the seedling rate is more than 90%. It has the advantages of high technological content, large production scale, low cost of seedling cultivation, good quality, and labor saving. The price of rice factory grown seedlings is about 30 yuan/mu (not suitable for seeds), which is highly welcomed by farmers.

1、 Selection of sowing production line.  2BLY-280B seedling and sowing machine (assembly line) jointly developed by Jiangsu Agricultural Machinery Promotion Station and Jiangsu Yunma Agricultural Machinery Manufacturing Co., Ltd. This seedling and sowing assembly line adopts a spiral seed metering device, which can adapt to the seedling and sowing of all rice varieties. High sowing accuracy, low hole rate, and uniformity of over 90%. The upper and lower soil, sowing, covering soil, and spraying water are completed in one operation, with a shift yield of 5000-6000 trays. Mechanized transplanting requires about 25 standard seedlings per acre of rice field, and the machine price is about 20000 yuan. At present, there are also supporting production of automatic hanging machines, automatic closing machines, soil crushers, soil loading machines, awning machines, dehydration machines, and power conveyor lines for factory seedling cultivation, greatly reducing labor costs and meeting all the needs of factory seedling cultivation.

2、 The selection of rice paddies. Centralized seedling cultivation can be carried out in greenhouses, fields, or dry fields. When raising seedlings in the field, it is necessary to choose a flat, fertile, easy to drain and irrigate, and windward and sunny sandy field to facilitate the growth of seedlings and the lifting of seedlings during transplantation. The rice paddies should be well furrowed and fenced, and the area of the rice paddies should be drained. The rice paddies can only be placed after the skin is dried tightly. The seedbed for dry seedling cultivation should be windward and sunny, fertile and loose. Flat plots, dry fields, and twilight fields should be plowed and finely leveled, and then decomposed farmhouse manure should be applied to flatten and remove the slurry. Then, a layer of thin mud should be laid and smoothed before laying the pan. 7-8 square meters of seedbed per mu.

3、 Seed processing. Select excellent rice seeds, soak and disinfect them after cleaning, and then induce germination at 36-38 ℃ for 12-15 hours, with a bud length of about 0.5mm (similar to ant eggs). After the rice seeds that have been germinated are dried, they can be sown on the sowing production line (the air suction seeder must first remove the rice seeds). 4、 Nutrient soil preparation. 1. Take sticky ripe soil and add 5 kilograms of ripe manure per acre, or a small amount of manure water and 0.5 kilograms of superphosphate, and mix well. Disinfect 6-8 grams of Diclofenac pine per acre with water and stack for one month. If the pH value is greater than 7 or alkaline, acid adjustment treatment (adding 70-100 grams of fine sulfur powder to reduce the pH value) is required. Then, after air drying, crushing, and screening, machine sowing can be carried out on the sowing production line. Nutritional moisture content must be less than 3%. 2. You can also use sticky mature soil, which is air dried, powdered, and sieved. After adding 2 kilograms of seedling strengthening agent to every 100 kilograms of nutrient soil, it can be directly machine sown on the planting production line, with a soil consumption of 40-50 kilograms per acre.
