    Technology Daily Changsha, Nov. 20 (Reporter Yu Huiyou correspondent Li Jianwu) super rice high yield, well known, but it is delicious, green? On the 20th, the reporter learned from Hunan Hybrid Rice Research Center that the "13th Five-Year Plan" national key research and development plan for grain-rich and efficient scientific and technological innovation under the auspices of the
    Yuan Longping team of the Chinese Academy of Engineering - "The integration and demonstration of green high-quality production efficiency technology for the anniversary of Hunan double-season rice" "The project has made new progress: the project technology system integrated biological and physical non-chemical control technology, not only can significantly reduce the amount of chemical pesticides, but also through the combination of high-quality rice yield, full mechanization and other cultivation technology, to achieve rice safety, high-quality, productive and efficient full-course green production." This year, the total yield of double-season rice is 1365 kg per mu, which is a new high in China's double-season rice production.
    , deputy director of the National Science and Technology Center, said the team established a demonstration area of 10,000 mu of super rice engineering in Linyi County, Changde City, Hunan Province. Among them, the two-season super rice model demonstration area of 2500 mu, early rice planting is high-product strains two excellent 819 and plant two excellent 173; "Demonstration rice cultivation, to red-eyed bees to control rice pests mainly, supporting fan-sucking beneficial isolation trap lamp protection and control, rice field natural enemy protection and habitat control, rational application of organic fertilizer, auxiliary biopesticide disease prevention and biological fertilizer control and other technologies, the whole process is a green production technology system."
    It is learned that in July and November of this year, Hunan Agricultural Society organized early and late rice on-site production acceptance, early rice yield of 591.7 kg per mu, late rice yield of 773.3 kg per mu, the total yield of rice in both seasons of 1365 kg per mu, creating a new high in China's double-season rice production. This "achievement" is about 30% higher than the average two-season rice high-yielding area, and about 50% more than the average rice yield in Hunan. At the same time, the demonstration film fertilizer, saving, economic ecological benefits are particularly significant. According to calculations, the average yield of early rice mu than a large area increased by 259.7 kg, an increase of 623.3 yuan per mu. The average yield per acre of late rice increased by 290 kg over a large area, and the yield per acre increased by 730.8 yuan. Two seasons down, an increase of 1354.1 yuan per acre.
