1960 1 1.5, China's first imitation missile was successfully launched, China's first atomic bomb was successfully exploded in 1964 16 15, and China became the fifth country with an atomic bomb; 1967 June 17 at 8: 00 am, China's first hydrogen bomb was successfully exploded in the air;
China's first artificial satellite was successfully launched on 2 1 on April 24th, 0970, and China became the fifth country to launch an artificial satellite. China's "two bombs and one satellite" is a brilliant cause created by the Chinese nation in the second half of the 20th century.
2. Shenzhou 5
The Shenzhou 5 spacecraft carrying astronaut Yang Liwei was launched at Jiuquan Satellite Launch Center at 9: 00 Beijing time on June 65438+/KLOC-0+May 2003, with an orbit of 14, which lasted 2 1 hour and 23 minutes. Its return capsule returned to Inner Mongolia on June 65438+1October 65438+June 6, 2003 at 6: 23 Beijing time.
Shenzhou 5's successful launch has realized China people's dream of flying for thousands of years. It is a highly condensed wisdom and spirit of the Chinese nation and a new milestone in China's space industry in the 2 1 century.
3. Hybrid rice
China is the first country in the world to successfully develop and popularize hybrid rice. Yuan Longping was transferred to Hunan Academy of Agricultural Sciences in February of 197 1, specializing in hybrid rice research.
1973, the scientific and technological research team headed by him completed the three-line matching, successfully cultivated hybrid rice, and achieved a historic breakthrough in hybrid rice.
1In June, 1984, Hunan Hybrid Rice Research Center, a national hybrid rice research institution, was established, followed by the National Hybrid Rice Engineering and Technology Research Center, with Yuan Longping as the director of the center.
1986 put forward the development view of "two-line method using heterosis between subspecies" After six years of hard research, the key technology of two-line hybrid rice was successfully broken through, and it was popularized with scientific researchers, and achieved good yield-increasing effect.
1997 put forward the technical route of "super-high-yield breeding of hybrid rice", which attracted great attention in the world.
Under his leadership, in 2000, 2004, 20 1 1 year, the first, second and third phases of super rice yield of 700 kg, 800 kg and 900 kg per mu were realized, and in 20 1438, the super rice yield per mu was also realized.
1995 was elected as an academician of China Academy of Engineering. Known as the father of hybrid rice.

5. Shenzhou XI
Shenzhou XI was launched on 20 16 and 10, and entered the scheduled orbit. 20 16 10 19 realizes automatic rendezvous and docking with Tiangong-2, forming an assembly; 20 16, 165438+ 10, 18, the return capsule landed at the main landing site, and the manned mission was completed.
Shenzhou XI has realized the process from the second step to the third step of China's manned spaceflight project, laying a solid foundation for the construction and operation of China's space station and the long-term presence of astronauts.
