三亚：向种突破，向海图强｜活力中国调研行

Core Insights - The article highlights the development of the Sanya Yazhou Bay Science and Technology City, which focuses on agricultural technology and salt-tolerant rice breeding to enhance food security in China [1][3]. Agricultural Innovation - The Sanya Yazhou Bay Science and Technology City has introduced numerous salt-tolerant rice varieties, achieving yields of 327.2 kg per mu under 5‰ saline conditions and over 400 kg per mu under 3‰ to 5‰ saline conditions [1]. - Over 70% of the more than 20,000 crop varieties developed since the founding of New China have been nurtured through the South Breeding program [1]. - The city has evolved from a traditional breeding base to a comprehensive service hub for research, production, sales, and technology transfer, referred to as the "South Breeding Silicon Valley" [1]. Industry Collaboration - The technology city has attracted over 20 leading national seed companies and more than 100 ecosystem enterprises, forming a robust seed industry cluster [3]. - A collaborative platform for breeding innovation has been established, integrating research institutions, universities, and enterprises to provide full-chain services from research to field management [3]. Talent Acquisition - The city has successfully attracted over 1,300 high-level talents in the South Breeding field, including five academicians, and has set up multiple innovation centers and workstations [4]. - It has also established branches of ten agricultural universities, enrolling 2,178 graduate students in agricultural disciplines [4]. Technological Advancements - The Sanya Yazhou Bay Science and Technology City has made significant strides in deep-sea research, with the successful sea trial of a deep-sea mining vehicle capable of operating at depths of 4,000 meters [5]. - The proximity to deep-sea areas enhances the city's capabilities for deep-sea research and experimentation, with major research institutions and enterprises establishing a presence in the area [7][8]. Intellectual Property and Technology Transfer - A national-level intellectual property protection center has been established in the city, facilitating accelerated patent authorization for seed-related innovations [4]. - As of December 2024, the city has registered 186 contracts for the transfer of South Breeding technology, with a total transaction value of 270 million yuan [4].
