大米草原产英国、法国沿海,是欧洲米草和美洲互花米草的天然杂交种,因其植株比亲本高,因此称之为大米草。大米草是多年生禾本科植物,耐盐耐淹能力特别强,能在其他植物都不能生长的光滩和较低的滩面迅速扩展,绿化光滩,并为农牧业生产提供饲料、肥料和燃料,又能为轻工业提供大量的造纸原料。有些欧洲国家曾把海滩上种植大米草作为保滩、护岸、护堤,减少水利投资的生物学措施。从长远的观点看,海滩上种了大米草,可以促进淤积,提早围垦,增加滨海地区耕地面积,同时由于大米草的根群十分发达,可显著增加海滩土壤中的有机质和肥分,围垦后能加快脱盐养淡速度,便于提早种植粮、棉作 Rice grass native to the United Kingdom, the French coast, is a European and American Spartina alterniflora natural hybrids, because of its plant higher than the parent, it is called rice grass. Siberian grass is a perennial gramineous plant with particularly strong salt tolerance and flooding resistance. It can rapidly grow on light and low tidal flats that other plants can not grow, green light beach, and feed, fertilizer and fertilizer for agriculture and animal husbandry Fuel, but also for light industry to provide a large number of paper materials. Some European countries once used the planting of rice grass on the beach as a biological measure to protect tidal flats, revetments and berms and reduce investment in water conservancy. In the long run, the planting of rice straw on the beach can promote siltation, early reclamation and increase the cultivated area in the coastal area. At the same time, because the root of rice grass is very developed, it can significantly increase the organic matter and fat content of beach soil. After reclamation Can speed up the speed of desalination, facilitate the early planting of grain, cotton
