The drone equipped with a radar sensor hovers in the air, collecting corn growth data at different sites; the operating machine is equipped with fertilization system, and the quantitative supply of fertilizer is completed according to the data provided by the drone.

"This accurate fertilizer method has greatly improved fertilizer utilization." Said Chen Zhongguo, the head of the Nong'an County Village in Chenjiadian Village, Nong'an County, Jilin Province.

This intelligent technology has been widely used in Jilin Province.

In Gulfgou Village, Liufang, Liufang, Gongzhuling City, the family farm operator Yu Yang accepted Chen Guoshuang, a senior engineer of the Northeast Geography and Agricultural Ecology Institute of the Chinese Academy of Sciences last year, and brought out 15 acres of land to "taste the new". Mushrooms in the fields. Mix mushroom mushroom seedlings into the medium made of organic fertilizer and straw, and sow into the fields, which is equivalent to simultaneously giving farmland fertilizer, circulating efficiency and cultivation of land. The last account is calculated, and more than 1,300 yuan per mu.

This is a microcosm of the joint implementation of the "Black Earth Grain" science and technology in Jilin Province and the Chinese Academy of Sciences. In recent years, Jilin Province has joined the Chinese Academy of Sciences to build innovative platforms such as black land protection and utilization of national key laboratories, focusing on 28 key technologies in 6 aspects including the protection model, smart agricultural machinery equipment, and saline -alkali land improvement and utilization. At the same time, it also strongly supports agricultural industrialization leading enterprises, research and development institutions, financial institutions, and financial institutions to establish cooperation mechanisms to jointly build black land protection "industry -university -research push" platforms to promote collaborative innovation.

In May this year, the demonstration zone of Changchun National Agricultural High -tech Industry was established. In the smart farm of the Demonstration Zone of Gongzhong City, an unmanned agricultural machinery is driving the fields and accurately completing various instructions under the control of the integration perception system and the Beidou Quan unmanned driving system. Based on Academician Zhao Guochun's team, scientific research institute, and related data companies as technical support, smart agricultural machinery such as driverless driving straw back to field machines, no cultivation machines, etc.

“这些协同创新平台，既能研发阻断黑土地退化等共性关键问题，又能调动科研人员研发符合区域需求的特色技术。”吉林省农业农村厅有关负责人介绍，目前，仅中科院东北地理与The Institute of Agricultural Ecology has formed 22 main push technology.

Located in the White Beach Irrigation District of the Jilin Provincial Academy of Agricultural Sciences, Gasheng Township, Zhenxian County, the surrounding area was originally saline and alkali land, and now it has become a green rice field. Ma Wei, an associate researcher at the Institute of Rice Research, Jilin Provincial Academy of Agricultural Sciences, is busy testing rice diseases and preparing to popularize preventive measures to surrounding farmers.

"Through the experimental field, the large planting households are driven. The Jilin Academy of Agricultural Sciences will cultivate the new varieties of salt -alkali, high -quality rice, and high -quality rice varieties such as the" Ji Juju 816 ', and supporting technologies such as deep fertilization and straw to the field. " Introduction. As of the end of June, the promotion area of ​​the province of "Ji Juju 816" reached more than 1 million acres. With related agricultural techniques in the second year of planting, it can achieve 417 kg of heavy saline -alkali water fields per mu, which is nearly 7 times that of ordinary farmers' planting output, which helps help. The ecological governance of saline -alkali land in Black Earth Area has accelerated.

Accelerate the achievements of the transformation of scientific research, Jilin Province fully builds the provincial, city, county and township level promotion network, builds 3 demonstration bases for 10,000 acres, 30 acres of radiation demonstration bases. The service organization, 1,000 demonstration model villages, 10,000 new operating entities, and a batch of demonstration households, focusing on promoting the "pear tree model" of black land protection.

The scientific and technological innovation platform accelerate the transformation demonstration, the agricultural technology promotion system is becoming more mature, and the achievement of grain production and the quality of cultivated land in Jilin Province has achieved "dual improvement". In the past 5 years, the implementation area of ​​Jilin Province's protection has increased by 4.8 times, ranking among the top in the country. As of the end of last year, the average average arable land land in the pilot project area of ​​Jilin Province was 0.61 grades compared with 2018. The average increase in soil organic matter was 7.4%, and the thickness of the average cultivated layer of the dry field waterfield reached 25.84 cm. Last year, the total grain output of Jilin Province reached 80.784 billion kg, ranking among the top ten provinces in the country in the top ten in the country.
