Mining equipment. 8. The Yangtze River bridges in Wuhan and Nanjing, the Gezhouba Dam on the Yangtze River and Xiaolangdi on the Yellow River, and the Three Gorges Project under construction represent the construction capacity of bridges and dams, and the progress in transportation is demonstrated by the 10,000-ton mega-ships, the 7 passenger planes, the construction of highways, and the acceleration of trains. 9. The successful development of the Daqing oil field fully demonstrates the strength of China's self-reliance policy, while air-jet spinning and synthetic rubber show the ability to absorb and innovate technology. 10. The contribution of science and technology to agricultural progress has reached 35%, and great progress has been made in the promotion of good seeds and the reform of farming systems. Indica hybrid rice, Lu cotton 1 cotton, Tiefeng 1 and Dongnong 36 soybeans and wheat and the promotion of good varieties of crops played a huge role in increasing crop yields, crop varieties over the past 51 years replaced four or five times, each time an increase in yields of 20% to 30%, the main crops of good seed coverage has reached 80%, afforestation survival rate increased by 20%, the replanting index increased by 25%. 11.
