How far is the GM crop from us? On June 16th, in the report hall of the Crop Research Institute of the Chinese Academy of Agricultural Sciences, the reporter “experienced†the identification test of genetically modified cotton. Originally, to identify whether a crop was genetically modified, a test strip similar to acid-alkaline could be inserted into a test tube containing a crop of powdered liquid. Within a few minutes, the test strip could be Identify whether the crop is a genetically modified crop. "China's newly developed and world-leading hybrid three-line insect-resistant cotton, Yinmian No. 2, is China's first state-reviewed three-line supporting transgenic insect-resistant cotton." Chief Expert of Transgenic Cotton Three researchers told the reporter that the species had a two-year regional trial in the Yellow River Basin, which compared with the Controlled Cotton Institute41, yielded an increase of 26.4% per mu. Guo Sandui said that China has successfully applied transgenic technology to develop a batch of insect-resistant cotton varieties, and the three-line insect-resistant hybrid cotton is one of the most developed and popularized. It seems that GMO technology is not far away from our production and life. When it comes to genetically modified organisms, there may be many people who are unfamiliar with it. Even many people fear or reject genetically modified foods. Experts say this is because they do not understand GMO technology. "Actually, today our agriculture has been inseparable from biotechnology and can not be separated from genetic modification." Huang Da-P researcher who has long devoted to the research of agricultural biotechnology told reporters that most of the crops grown today are no longer natural evolution. The wild species, but after thousands of years of artificial breeding cultivars. Plant biotechnology is based on the development of modern life sciences, and combines advanced engineering techniques such as genetic engineering, cell engineering, enzyme engineering, fermentation engineering, and protein engineering, transforms plants in accordance with people's previous designs, and obtains genetically modified crops and their products according to human needs. . Transgenic technology is essentially an extension of traditional breeding methods, and its essence is the same as traditional conventional cross breeding. Traditional conventional breeding is the transfer of thousands of genes of different plant species or even different plant species at one time; genetic engineering is only transferring one or several genes, and is more accurate, more predictable and more efficient. In 1994, the first product of transgenic plants—storage-tolerant tomatoes—entered the market. After 1996, the industrialization of transgenic plants developed rapidly and became overwhelming. By the year 2005, the total area for the promotion and application of genetically modified plants in 21 countries in the world reached 90 million hectares. During the ten years from 1996 to 2005, the area under cultivation of global genetically modified crops had increased by nearly 53 times, and the cumulative cultivated area had reached 474.6 million hectares (7.119 billion hectares). , equivalent to 3.75 times the area of ​​China's arable land. At present, the transgenic plants widely used in large areas are mainly insect-resistant and herbicide-resistant varieties; in order to meet people’s needs for improving their quality of life, scientists are developing the requirements of drought resistance, salt tolerance, improved quality, increased nutrition, health care, and bioenergy. The second-generation and third-generation transgenic plants not only benefit consumers directly, but also make significant contributions to solving the global water shortage and energy crisis that are closely related to the daily life of consumers. The large-scale popularization and application of transgenic plants has created great economic benefits, while also making active contributions to reducing the use of pesticides, increasing farmers' income, and reducing farmland environmental pollution. According to statistics, scientists from the Chinese Academy of Agricultural Sciences have bred and validated 46 varieties of transgenic insect-resistant cotton, and planted more than 36 million mu in 2005; promoted 127 million mu of cultivated area over the past seven years, reduced the use of pesticides by 650,000 tons, and polluted farmland. The index dropped by 21%, creating social and economic benefits exceeding 22.1 billion yuan. In order to ensure environmental safety and human health, the Chinese government has established a highly scientific and strict agricultural safety evaluation and management system for genetically modified organisms. Every genetically modified plant variety or product that is approved for importation or commercialization by the government is evaluated through the strict food safety and environmental safety of agricultural genetically modified organisms. The currently selected GM crops are not harmful to human health, and food allergy accidents caused by genetic modification have not yet occurred. The safety of genetically modified foods in a sense even surpasses traditional foods, especially in microbial toxins, pesticide residues and nutrient content. In addition, the application of transgenic technology can also change the sensitization components of certain foods; the use of transgenic technology can also change the composition of seed oil, reduce the content of saturated fatty acids or reduce the deposition of heavy metals in fruits, seeds, etc., so that the food towards A healthier development. Mr. Ye Dawei, chairman of the Biotechnology Branch of the Plant Protection (China) Association, said: “Transgenic crops have played a major role in achieving the leap from traditional agriculture to modern agriculture. Correct understanding and utilization of genetically-modified technologies will certainly benefit humanity, and will be more able to be solved in China. The issue of agriculture, rural areas and farmers will make a huge contribution. We will continue to work hard to develop more efficient, highly nutritious genetically modified crops and use science and technology to create a better life.†Wide Vermicelli,Radish Juice Vermicelli,Wolfberry Juice Vermicelli,Sweet Potato Leaf Juice Vermicelli Ningxia ZhaiXianSong Commercial and Trading Co.,Ltd. , http://www.nxupin.com
GM, biotechnology around us
In the past seven years since China's transgenic insect-resistant cotton was promoted, the cumulative planting area has reached 127 million mu, reducing the use of pesticides by 650,000 tons and creating social economic benefits exceeding RMB 22.1 billion.
