"Transgenic insect-resistant cotton" allows China to regain its dignity

In late April, the Cotton Research Institute of the Chinese Academy of Agricultural Sciences in Anyang, Anhui Province (referred to as the China Cotton Institute), for the first time since its establishment, became the focal point of the major media of the central government—the implementation of the scientific concept of development organized by the Central Propaganda Department. The “Special Report Group for the Construction of Innovative Countries” conducted a joint interview with the heroic units and experts who completed the national key scientific and technological innovations “Transgenic insect-resistant cotton”. “The tiny bollworm once made us feel embarrassed or even humiliated. Today we finally found the dignity as a Chinese scientist!” In the face of the reporter, Li Fuguang, deputy director of the Institute of Genetic Research and Ph.D. Thousands. Related Links: Cotton is an important economic crop in China, and is an important economic source for 200 million cotton farmers. It involves 19 million workers in the textile and related industries. In 2005, China’s cotton textiles and apparel exports earned 115.2 billion U.S. dollars, accounting for 15% of all foreign exchange earnings. Cotton plays a decisive role in the development of our national economy. Since the 1990s, the bollworm has been destructive and has caused the country billions or even billions of yuan in economic losses every year. It is also not helpful for cotton farmers to control the cotton bollworm every year from the original two or three times to more than 20 times. This not only increases the cotton farmers' production cost and labor intensity, but also seriously damages the ecological environment and damages the cotton farmers' physical and mental health. According to incomplete statistics, from 1992 to 1996, cotton farmers poisoned more than 240,000 people because of controlling bollworms. People once put the bollworm in the pesticide solution, which is still at a leisurely pace. Farmers feed their own chickens from the bollworms that are caught in the cotton fields. Chickens are poisoned and die. The pesticides that kill people can kill dead insects. The dead insects can kill chickens. The resistance of cotton bollworms is terrifying and shocking. At that time, the Minister of Agriculture issued a “reward order”: Who can cure cotton bollworms? , Who will award 1 million yuan! Related links: With its one-step high-tech, foreign insect-resistant cotton entered the Chinese market in 1997, and in 1998 it occupied 95% of the market share of 3.8 million mu of insect-resistant cotton, while domestic insect-resistant cotton accounted for only 5%, the situation is very compelling. Once foreign countries use their means of production, cottonseeds, to control China’s cotton production, it will seriously threaten China’s cotton security. It is imperative to develop domestically produced transgenic cotton. “Whoever takes the lead in occupying the high point of cotton biotechnology will be able to control the future cotton market.” Yu Shuxun, head of the China Cotton Institute, said that at a time when China’s cotton production is seriously threatened by cotton bollworm, a U.S. company proposes US$90 million. Price transfer of transgenic insect-resistant cotton technology, but does not transfer its patent rights. In response, Chinese scientists solemnly suggested to relevant departments: “It would be better to invest funds to develop domestically produced transgenic insect-resistant cotton with independent intellectual property rights without having to purchase a large amount of money in the absence of a patent right.” Soon, scientists of the Chinese Academy of Agricultural Sciences adopted genetic engineering technology methods. Successfully developed a new type of Bt insect-resistant gene that is fused with unit price, making China the second country in the world with independent intellectual property rights for insect-resistant genes. Then it successfully developed a bivalent insect-resistant gene (Bt+CpTI) with international advanced level. In 2002, China Cotton Institute spearheaded the establishment of a platform for large-scale transgenic cotton technology, and creatively improved and established three highly efficient genetically-transformed methods, including Agrobacterium-mediated method, pollen tube pathway method, and particle gun bombardment method, and created an international The only technology platform that can quickly use the three methods simultaneously to obtain new transgenic insect-resistant cotton materials. At present, the Institute has obtained tens of thousands of transgenic insect-resistant cotton materials and has screened more than 2,000 new germplasm materials with valuable use, of which more than 600 have been provided to breeders to breed new varieties and directly develop insect-resistant cotton from them. More than 10 new varieties, accumulatively cultivated more than 20 new varieties, accelerated the research and development of domestic insect-resistant cotton. This achievement won the second prize of National Science and Technology Progress Award in 2005. The China Cotton Institute also cooperated with local governments in the three major cotton regions of China and established eight regional joint ventures with complementary advantages. It has formed a national industrialization system centered on China Cotton Institute and established a new insect-resistant cotton. More than 200 varieties of demonstration sites have promoted the rapid development of domestic insect-resistant cotton. By 2005, domestic insect-resistant cotton has been promoted to more than 90 million mu, with a market share of 70%, creating social benefits and economic benefits of more than 15 billion yuan. The large-scale planting of transgenic insect-resistant cotton made it possible to effectively control the damage of bollworm pests at the time of production. The use of pesticides has been reduced by 60% to 80%, which has greatly reduced the incidence of poisoning by humans and animals. The labor intensity and prevention and control costs of cotton farmers have been significantly reduced, and the ecological environment of cotton fields has decreased significantly. Obviously improved. Related links: Transgenic insect-resistant cotton is the earliest and the largest area of ​​genetically modified crops in China. It is the most successful representative of genetically modified plants in China. By 2005, more than 20 domestic insect-resistant cotton varieties had obtained the production application safety certificate issued by the Ministry of Agriculture and passed national examination and approval. The output of domestic insect-resistant cotton can usually increase production by 10% to 20%, and the fiber quality is equivalent to or better than that of conventional cotton. The new cotton varieties such as China Cotton Institute 41 and 45 were listed as key national varieties, and they were granted subsidies for new varieties of the country.

Consumer electronics refers to the audio and video products used by individuals and families in relation to radio and television. They mainly include: TV sets, DVD players, VCRs, camcorders, radios, tape recorders, , Record players, compact disc players (CDs) and more.

In some developed countries, however, telephones, personal computers, home office equipment, home electronic Health Care equipment, automotive electronics, etc. are also classified as consumer electronic products. With the advent of technology and new applications of new products, digital cameras, mobile phones, PDAs and other products are emerging as emerging consumer electronic products.

Since the late 1990s, information appliances integrating three fields of computer, information and communication, and Consumer Electronics have begun to penetrate into family life extensively. It has such functions as audio-visual, information processing and two-way network communication, Processor, associated supporting hardware (such as a graphics card, storage media, IC card or credit card reading device), embedded operating system and application layer software package. Broadly speaking, information appliances include all household appliances such as PCs, set-top boxes, HPC, DVDs, super VCDs, wireless data communication devices, video game devices, WEBTV, etc. that can exchange information through the network system. Currently, audio, video and communications equipment is a major component of information appliances.

In the long run, refrigerators, washing machines, microwave ovens and the like will also develop into information appliances and form an integral part of smart appliances.
