Unmanned technology makes rice cultivation green and efficient

Recently, the on-site observation and training meeting on green and high-yield unmanned cultivation technology of rice was held in Sihong County, Jiangsu Province. At the meeting, the unmanned rice direct seeder, Rice transplanter and other new operating equipment developed by the modern smart agriculture collaborative innovation consortium led by Yangzhou University “walked” in the rice fields, attracting the attention of agricultural scientists and large farmers from Jiangsu, Zhejiang, Shanghai and other places.

Relevant experts believe that the new unmanned rice cultivation products and unmanned machine insertion, drone rice direct seeding, and dry direct seeding technologies exhibited at this observation meeting have achieved breakthroughs and innovations in various aspects compared to traditional work tools and methods, and have played a good leading and demonstration role.

At the observation meeting, the unmanned cultivation technology of rice dense seedling machine insertion was quite impressive. This technology adopts equipment such as full straw returning unmanned land preparation machine and unmanned rice dense seedling Rice transplanter, takes the straw matrix block developed by the Agricultural science of Jiangsu Province as the seedling raising substrate, the light dense seedling technology cultivated as the core, and the one-time application technology of machine transplanted rice controlled mixed fertilizer, green flying prevention technology of disease, insect and grass UAV, etc., forming a technical system of unmanned rice dense seedling machine planting.

The unmanned plowing and land preparation technology uses unmanned tractors as the carrier to achieve high-quality straw return to paddy fields, fine plowing and land preparation, and other unmanned plowing and pulping operations. Zhang Hongcheng, an academician of the CAE Member and a professor of Yangzhou University, introduced that the machinery used in this unmanned land preparation technology is the Dongfeng DF1204-CVT (G4) unmanned tractor, which is equipped with an efficient chain stepless transmission Powertrain, equipped with a remote control system, and has realized work path planning, App remote interaction and unmanned operation. The driverless tractor can achieve ultra deep rotary tillage with a rotary tillage depth of 22cm or more by pulling the double axle rotary tillage paddy field tillage and slurry leveler developed by Yangzhou University and using the double axle layered cutting principle; The application of intelligent level control system has greatly improved the flatness of paddy fields and completely solved the problem of difficult leveling of ridges.

Yang Hongjian, the head of Jiangsu Provincial Agricultural Technology Promotion Station, said: “These new products and technologies of green and high-yield unmanned cultivation of rice have made brilliant innovations on the basis of the past unmanned cultivation technology system. Starting with seedling raising, land preparation, Rice transplanter seedling loading and other links, they have reduced labor costs, improved the quality of operations, and developed technologies from the perspective of ‘farmers are willing to use’, making a big step towards the future of truly unmanned rice cultivation.”
