High-quality rice in Mengzi

　　Mengzi started cultivating high-quality rice early on. Since 1996, it has introduced 13 varieties for trial planting, screening, and technical research. Among these, the "three-nursery system" was adopted to propagate the original seeds of high-quality conventional rice varieties "Yunhui 290" and "Diantun 502."

Field trials showed that the purity of "Yunhui 290" reached 99.99%, and "Diantun 502" met the first-grade seed standard in field inspections. The purified and rejuvenated original seeds of "Yunhui 290" demonstrated enhanced resistance and superior quality. Currently, the county has expanded high-quality rice cultivation to 51,000 mu, with an average yield of 557.6 kilograms per mu, totaling 28.4454 million kilograms, and produces 17.0672 million kilograms of high-quality rice annually.
