大米草(Spartina anglica)为多年生禾本科植物,原产于英国南海岸海滩上,1963年先后引进四批种苗和种子,在浙江、江苏等省的海滩上试种成功,并在栽培、繁殖、综合利用和推广工作方面取得了一定成果。1979年10月统计,我国大米草的种植面积达47万亩以上,北起辽宁省锦西县(北纬40°45′),南至广东省电白县(北纬21°30′),已突破北回归线(北纬23°30′),破除了关于热带地区不能引种大米草的传统定论。现已有80多个沿海县(市)种植了大米草。
Spartina anglica, a perennial gramineous plant native to the South Coast beach of the United Kingdom, introduced four batches of seedlings and seeds successively in 1963 and succeeded in planting on the beaches of Zhejiang and Jiangsu provinces. In cultivation and breeding Some achievements have been made in comprehensive utilization and promotion. Statistics from October 1979 showed that the planting area of rice grass in our country reached more than 470,000 mu. It started from Jinxi County in Liaoning Province (40 ° 45’N, N) to Dianbai County in Guangdong Province (21 ° 30’N, South China) The Tropic of Cancer (23 ° 30’N) has broken the traditional conclusion that tropical rice can not be introduced. There are now more than 80 coastal counties (cities) planted with rice grass.
