1509.5 kg! The double-season yield per mu of hybrid rice developed by Yuan Longping team was bumper.

　　1509.5 kg! On the morning of November 26th, in Yangtian Village, Huangpu District, Guangzhou City, Guangdong Province, the Huangpu Demonstration Base of the National Hybrid Rice Engineering and Technology Research Center, which tackled the problem of high-yield double-cropping rice with a yield of 3,000 kg per mu, carried out the yield measurement and acceptance of late rice.

　　At about 12 o’clock in the morning, Luo Xiwen, an academician of China Academy of Sciences, read out the results at the scene. The results show that the average yield per mu of late rice in the base is 726.4 kg, and the average yield per mu of early rice this year is 783.1 kg, and the yield per mu of hybrid rice in double seasons is 1509.5 kg.

　　Regarding the rice harvest in the demonstration base, Luo Xiwen thought that "the whole rice harvest was good". "Planting crops pays attention to improved varieties, good methods, good fields and good conditions ‘ Siliang ’ Matching. " Luo Xiwen said that paddy fields should be improved continuously to get a good rice harvest. However, the 30-mu field in Huangpu Demonstration Base was cultivated only last year, which is not considered as "the best fertile field". Due to the lack of water in the first half of the year, the early rice in the demonstration base was delayed by more than 20 days, which affected the planting of late rice, which would also affect the yield of late rice.

　　He believes that strictly speaking, it is more difficult for Guangdong to grow rice in this place and achieve high yield. The small temperature difference between day and night in Guangdong is not conducive to the transformation of crop protein and starch, and high temperature and rainy weather will also bring pests and diseases. "This is not the best ecological environment for rice, but we must choose this place, which is what Mr. Yuan Longping asked us to do before his death." Luo Xiwen said, we want to realize the 3,000 Jin per mu of double-cropping rice mentioned by Mr. Yuan Longping under the climate conditions in Guangdong, and we hope that this year and next year’s efforts will truly realize Miss Yuan’s dream. "

　　It is reported that the base was personally deployed by Academician Yuan Longping before his death and built by Huangpu Research Institute of Agricultural Science and Technology in Longping. Li Jianwu, executive vice president of Longping Agricultural Science and Technology Huangpu Research Institute, introduced that Yangtian Village, where the demonstration base is located, is 29 meters above sea level, with an area of 30 mu, with a total of 9 hills. The soil fertility of the demonstration base is moderate, which belongs to riverbed sandy soil. Late rice was sown on July 23rd, transplanted on August 12th, and transplanted by machine. The row spacing between plants was 4×8 inches, with 18,000 tillers per mu, and the heading began on October 7th. The variety was Xiangliangyou 900 (Chaoyouqian).
