In December 2020, Yuan Longping, the "father of hybrid rice", presided over the last hybrid rice high-yield research meeting in Sanya, Hainan, and proposed that multiple double-cropping rice producing areas, including Hainan and Hunan, jointly tackle the goal of an average yield of 3,000 catties of double-cropping rice per mu, and urged everyone to "implement it". On October 26, the results of the double-cropping rice production of the Nanfan Public Experimental Base in Yazhou District (Batou) of Sanya City, Hainan Province were announced, and the yield of hybrid rice double-cropping rice reached 1586.86 kg per mu, creating the highest record for double-cropping rice yield in Hainan.
