Yuan Longping team super rice yield an average of 1090.2 kg per mu

22, the Chinese Academy of Engineering
Yuan Longping team super hybrid rice 100 mu pieces 18 tons / ha of attack, located in Liangshan County, Sichuan Province, Dechang County, Texas town of Lutang village ultra-high yield attack demonstration point for production inspection and acceptance. After field site inspection, the expert group according to the Ministry of Agriculture and Rural Affairs super rice production method, randomly selected 3 fields mechanical harvest, the measured results of the average rice yield of 1090.2 kg / mu.
County is located in the Anning Valley area across the eastern edge of the Mountain Kang-Tibet Plateau, for the subtropical plateau monsoon climate, basic farmland protection area of about 180,000 mu, rice cultivation area of nearly 100,000 mu. Yuan Longping selected the demonstration area of 100.2 mu, good soil irrigation conditions, day and night temperature difference, suitable for rice dry material accumulation.
Li Jianwu, director of the cultivation room of the National Hybrid Rice Engineering and Technology Research Center, said that this year the team carried out 18 tons/ha of large-area demonstration planting at three points in Yunnan, Hebei Province and Sichuan Dechang, using Yuan Longping
to guide the selection of the fifth phase of super hybrid rice "super-excellent thousand". The variety is based on the two-line infertility system "Guangxiang 24S" and the strong and excellent recovery R900 selected by Hunan YuanTron Super Rice Technology Co., Ltd. as the parent, and is made of two-series hybrid medium rice combination. Varieties of leaves in good shape, resistant to fertilizer and anti-falling, good yield.
this year, in the cultivation management, the team on the basis of last year's improvement, integrated the super hybrid rice "four good" matching, soil testing formula fertilization, the application of new carbon-based fertilizer, anti-retromorphic microbial fertilizer, anti-decay strong seeds and other technologies. The effective spike per acre is expected to be 180,000, the total number of grains per spike 275 grains, the syringe rate of 90%, the thousand grain weight 27 grams, the theoretical mu yield of 1203 kg.
Finally, the Sichuan Provincial Agriculture and Rural Affairs Department and the Sichuan Provincial Science and Technology Department organized by the China Rice Research Institute, Hunan Provincial Agricultural and Rural Affairs Department, Sichuan Province Agriculture
, Yunnan Province Agriculture
, Chongqing Agriculture
, Sichuan Agricultural University, Liangshan County Agricultural Technology Extension Station and other units of experts, after the test and acceptance, it is believed that the rice growth is strong, long-term uniform, high grain, high yield, good color, no obvious pests.
