The development of the beach’s temperate plant “rice grass” has been successfully introduced at Dianbai County, Guangdong Province, located on the northern edge of the tropical belt. In October 1974, Dianbai County started to introduce the “rice grass” from Zhejiang into the beach of Pearl Farm of the Nanhai Commune Battalion Battalion.

In a tropical climate environment, “Spartina” has maintained its original features of salt tolerance, inundation resistance, strong adaptability and reproductive ability after being resisted and adapted. Some characteristics related to temperate “rice Grass ”different characteristics. 1. Plant height: The ratio of plants to rice in Britain and Zhejiang
