Do you know which space technologies are affecting our lives? 1 space breeding and its significance.

Space breeding, also known as space mutation breeding or space breeding, is a new breeding method integrating space technology, biotechnology and agricultural breeding technology, and is one of the most advanced scientific technologies in the agricultural field in the world today. It uses satellites, high-altitude balloons or manned spacecraft to carry samples such as crop seeds and microbial strains into space, and uses space conditions such as microgravity, high vacuum, high cleanliness, large temperature difference, weak magnetic field and high-energy particle radiation that cannot be simulated on earth. The mutation of biological materials causes the genetic variation of species, and then returns to the ground to select new germplasm and cultivate new varieties. Because of the shape, physiology and evolution of plants on the earth, they have been deeply influenced by the earth's environment for hundreds of millions of years. Once they enter space, their microgravity level, vacuum degree, proton and electron radiation content, atmospheric structure, temperature, air density, air pressure, geomagnetic intensity, radiation flow and strong ultraviolet radiation are very different from those on the ground. These spatial conditions,

Compared with the traditional ground mutation breeding, space breeding has the characteristics of large variation range, many beneficial variations, strong stability and short breeding cycle. Conventional breeding usually takes .. 5 ~ 8 years, while space breeding only takes .. 3 ~ 4 years, which greatly accelerates the breeding speed. Space breeding can produce sterile lines and provide new germplasm resources for further ground hybridization and cultivation of new varieties. Using space breeding can greatly improve crop yield and crop resistance and improve crop quality. In addition, more importantly, compared with genetically modified food, space breeding has no potential safety hazard. In fact, space breeding is only the variation caused by internal recombination and mutation of DNA, which belongs to the improvement of endogenous genes, and there is no genetic safety problem without the addition of exogenous genes. Therefore, space breeding is an effective way to cultivate high-yield, high-quality, early-maturing, multi-resistant and safe varieties.

2 China's achievements in space breeding

China breeders carried seeds such as green pepper, wheat and rice for the first time on China's ninth recoverable satellite, which was launched on August 5, 1987/KLOC-0, and started a beneficial attempt of space breeding in China.

China opera influences our life. Please tell us what influences (urgently) the value of art appreciation: cultivating sentiment.

Sculpture: There are some artworks that can learn from the shapes of traditional Chinese opera characters, such as the clay figurine Zhang in Tianjin, and many traditional Chinese opera shapes.

Music: Some music is more popular because of the elements of traditional opera, such as Li Yugang's songs, and there are several such songs in Wang Leehom.

Literature: Ye Guangqin, a famous writer, wrote The Story of Bean Juice, xiaoyaojin and other works, all of which mentioned the West District, which means that opera is also a good literary creation theme.

Film and Television: Farewell My Concubine, Leslie Cheung, ZhangFeng yi, etc. There are also many film and television works with the theme of expressing the stories of opera actors. Because sometimes opera can often be used as a symbol of a certain era. If you want to create a film and television with that era as the background, opera is essential.
