In the 1940s and 1950s, information dominated.

The third technological revolution. From the overall field of science and technology, human society has experienced three times since18th century.

Technological revolution: the first technological revolution led by machinery, the second technological revolution led by electricity and the third technological revolution led by information. Every technological revolution stems from one or two fundamental and powerful technological breakthroughs, which leads to the establishment of a new technological system and the upgrading of new industries. Three technological revolutions and three industrial upgrades have pushed human society from an agricultural society to an industrial society and created a modern civilization of human society. In this process, agriculture has lagged behind industry for nearly 200 years. Driven by the first agricultural technology revolution led by breeding technology, agricultural machinery and chemical technology, agriculture has developed at a high speed by the middle of this century. Therefore, major breakthroughs have been made in biological science and biotechnology. In 1950s, the double helix structure of genetic material deoxyribonucleic acid was discovered. DNA recombination in 1970s pushed molecular biology and biotechnology to a new stage of development. Subsequently, computer and information technology led to the arrival of the information age, and the rise of modern technologies such as new materials, aerospace and automatic control, which made agriculture face a new scientific and technological revolution, which would be dominated by biotechnology and information technology. If we seize the opportunity of this new agricultural science and technology revolution, it will lead to the revitalization of agriculture and rural economy in China. According to the research and analysis of the development of agricultural science and technology at home and abroad, the characteristics and trends of the new agricultural science and technology revolution in the emerging world are summarized as follows:

Agricultural science and technology are developing in depth and breadth, and major breakthroughs in scientific research are making qualitative leap and revolutionary changes in agriculture, rural economy and rural society. 2 1 century, agricultural science and technology will make great breakthroughs in exploring the mysteries of life activities of animals, plants and microorganisms such as crops, livestock, poultry, fish and shrimp, and making efficient use of water, soil, light and heat resources, so as to combine high yield, high quality and high efficiency of agriculture to a new level.

Modern agricultural science is moving towards new integration and union while the disciplines are differentiated, differentiated and updated. Compared with traditional agricultural science and technology, modern agricultural science and technology has five remarkable characteristics: intelligence, materialization, industrialization, enterprise and internationalization.
