Relying on science and technology to improve the market competitiveness of corn in China

Introduction: On September 5, it was learned from the 9th Asian corn conference jointly organized by the Chinese Academy of Agricultural Sciences and the international corn and Wheat Improvement Center (CIMMYT) and organized by the Crop Science Research Institute of the Chinese Academy of Agricultural Sciences that in order to enhance the market competitiveness of corn, China will vigorously improve the technical level of corn production by focusing on the selection of new varieties and the research and development of cost-saving and efficiency increasing production technologies; and Based on the Germplasm Foundation of wide corn breeding, we should pay attention to the research and development of biotechnology and the combination with conventional technology to continuously cultivate new varieties with high yield, high quality and multi resistance We should start with the technology of balanced fertilization, disease prevention and reasonable planting, and pay attention to the supporting cultivation technology of varieties We should start with the research and development of special compound fertilizer, conservation tillage and small agricultural machinery to study the production and cultivation technology of cost saving and efficiency increasing Quasi chemical production base construction and technical training, actively promote excellent varieties and supporting cost-effective production and cultivation technology, strive to improve product quality, reduce production costs, and accelerate the formation of corn industry belt with market competitiveness Since 1998, with the rapid development of the world economy, especially in developing countries, the demand for corn in the international market has grown much faster than that of other food crops, and corn has become the world's largest crop In Asia, the growth rate of demand for corn is far faster than that of rice and wheat, making it the most active region in corn production, consumption and import trade In China, corn is also an important feed, food and industrial raw material crop At present, China's corn planting area is 23 million hectares, the popularity rate of corn hybrids is 88%, the coverage rate of improved varieties is 90%, the total production and consumption are about 126 million tons, and the supply and demand are basically balanced However, with the growth of population and the adjustment of industrial structure, corn supply shortage will become a long-term trend It is predicted that by 2010, China's corn production and demand gap will reach 23.01 million tons Therefore, only by relying on scientific and technological progress can we meet the huge demand for corn in Asia in the future The theme of the 9th Asian corn conference held in Beijing is "relying on science and technology to meet the rapid growth demand of Asian corn" It aims to find a new breakthrough in the field, channel, mode and content of cooperation by reviewing and summarizing the past experience of Asian countries in corn science and technology cooperation More than 150 experts and scholars from 16 countries in Asia, Africa, America and Europe focused on the important progress of corn genetics, breeding, biotechnology, plant nutrition, physiology and plant protection, and discussed the direction and key research fields of corn science and technology progress This conference is the most fruitful high-level corn science and technology event in Asia It is the second time to hold the Asian corn science and technology conference in China after 17 years It will have far-reaching significance to promote the development of corn science and Crop Science in China, increase international exchange and cooperation, promote the development of seed industry in China and integrate into the Asian market.
