Since May, China has started a nationwide large-scale seawater rice planting. Seawater rice, a saline-alkali-tolerant type of rice, was designed to grow in tidal flats or other areas with heavy salt concentrations and developed through crossbreeding and other technologies.

In 2022, China plans to turn 1 million more mu (66,667 hectares) of saline-alkali land into rice fields.
