China News Service, Qingdao, October 16 (Reporter Hu Yaojie) It is the 40th World Food Day. The reporter learned from the Qingdao Sea Rice Research and Development Center on the 16th that the "Father of Hybrid Rice" and the academician of the Chinese Academy of Engineering Yuan Longping Qingdao Sea Rice Team The production has been tested and harvested in Qingdao, Weifang, and Wenzhou. So far, the team has completed the production evaluation of 100,000 mu of sea rice planted in Xinjiang, Qinghai, Inner Mongolia, Ningxia, Shandong, Heilongjiang, Zhejiang and other provinces and autonomous regions this year.
The evaluation team composed of industry experts conducted the sea rice production evaluation in the three places. The final expert's measurement result was that the yield of salt-tolerant rice with Qingdao base number yc-2003 was 542.5 kg per mu, and the yield per mu of Chaoyouqian was 739.7 kg; The salt-tolerant rice yield per mu in Weifang Base No. yc-2003 is 625.3 kg; the salt-tolerant rice yield per mu in Ruian Base No. yc-2002 in Wenzhou is 320.78 kg.
According to reports, the Qingdao sea rice team launched a ten thousand acres of saline-alkali land rice improvement and sea rice planting demonstrations this year. The demonstration planting area of sea rice has been extended from 20,000 mu to 100,000 mu.
Since September 25, the production of 100,000 mu of sea rice has been measured successively, and the measured yield per mu in Kashgar, Ningxia, Shizuishan, Heilongjiang, Dongying, Shandong, Weifang, Shandong, Qingdao and other places have all exceeded 1,000 catties.

Li Jiming, deputy director of research and development of Qingdao Sea Rice Research and Development Center, said that the scale of sea rice trial planting has been continuously expanded and the variety has been continuously improved. The yield per mu has been increasing year by year. The average mu has reached more than 500 kg, and the highest yield has exceeded 800 kg.
Li Jiming said that by promoting the cultivation of "sea rice", not only has 100 million acres of barren beaches turned into granaries, but also through the operation of agricultural machinery, smart agricultural technology and biological fermentation engineering demonstrations and farmland field demonstration teaching methods to create "sea rice planting + smart agriculture" "The whole industry chain; through intelligent and informatized services, provide smart home, smart medical, smart education, smart finance and other smart life experiences, forming a three-industry combination with sea rice as the core, wetland restoration as the responsibility, and cultural display as the goal Integrated development demonstration area.
It is reported that the Qingdao sea rice team will achieve the goal of 100 million mu of saline-alkali land transformation and improvement within 8 to 10 years, use the Internet, big data, cloud computing, artificial intelligence and other technologies to drive the digital transformation of China’s agriculture, and build modern agricultural industrial parks based on local characteristics. The integration of primary, secondary and tertiary industries and rural revitalization will realize the promotion of sea rice and the development of the entire industrial chain, providing classic cases and models for the reform of the ecological civilization system.
At present, China has about 1.5 billion mu of saline-alkali land, of which about 300 million mu has the potential to be converted into farmland. Academician Yuan Longping believes that if China can develop 100 million mu of saline-alkali land to grow rice, with a yield of 300 kg per mu, the total output can be increased by 30 billion kg, which will help ensure food security. At present, Yuan Longping's sea rice team has basically completed the contracted transformation of 1 million mu of sea rice. (Finish)
