On the multifunction machine equipped with the global positioning system, the screen of the electronic display screen is touched by hand, and the sowing and fertilization of winter wheat are completed together. This is the scene of the first intelligent variable seeding, fertilization and rotary tillage compound machine in China, which was actually operated in Songjiang Fuxin Farm in Shanghai.
China's first intelligent variable seeding, fertilizing and rotary tillage compound machine with independent intellectual property rights was successfully developed by the School of Mechanical Power of Shanghai Jiaotong University and put into use in Shanghai Songjiang Fuxin Farm. Its advent marks that China's digital agricultural technology has reached the world's advanced level.
According to the introduction, GSP-based intelligent variable seeding, fertilization and rotary tillage compound machine can scientifically analyze the farmland soil condition by electronic information technology, and then scientifically carry out precise variable fertilization and sowing according to the data analysis results, which can greatly save the seed fertilizer. The amount of use and the reduction of agricultural inputs will not only increase the planting benefits, but also help protect the ecological environment.
For agricultural countries like China, precision agriculture technology is of great significance. Due to the low utilization rate of chemical fertilizers, the annual loss of nitrogen fertilizer in China has reached 13 million tons, equivalent to more than 300 billion yuan. While wasting resources, the damage to the ecological environment is also growing. Such problems are widespread in countries all over the world and have aroused widespread concern in the international community.
Precision agricultural technology has developed rapidly in foreign countries, and the technical system has gradually improved. It has become a frontier research field for the major developed countries to rationally use agricultural resources in the 21st century, improve crop yields, reduce costs, reduce environmental pollution, and improve the competitiveness of agricultural products in the international market.
Professor Liu Chengliang, director of the Institute of Mechanical and Electrical Engineering of Shanghai Jiaotong University, and other scientific research personnel, with the support of the Ministry of Science and Technology and the Ministry of Agriculture, after more than two years of collaborative research, finally developed a machine-electric-liquid-suitable for China's national conditions. "Integrated intelligent composite machine, the project has completely independent intellectual property rights, has applied for 8 patents, and passed the national agricultural machinery testing and identification. Experts believe that this new technology fills a gap in the field of domestic agricultural machinery research.
