未来十几年内,欧洲和北美大地上可能会开始大量种植多年生草本植物——象草作为燃料发电,并有望真正替代煤炭和石油。象草因大象爱吃而得名,是热带、亚热带地区多年生草本植物,生长较快,植株可高达4米多,银色叶子,可燃性强。试验表明,这种植物能在大部分耕地上生长,不需施加肥料,不受病虫害困扰,收获后的干草能利用现有技术轻易制成燃料用于电厂发电。 In the next decade or so, large numbers of perennial herbaceous plants may be planted on the lands of Europe and North America - grass as a fuel for power generation and is expected to truly replace coal and oil. Elephant grass is named for the elephant’s love of eating. It is a perennial herb in the tropical and subtropical regions. It grows faster. Plants can grow up to more than 4 meters. Silver leaves are very flammable. Experiments have shown that this plant can grow on most of the cultivated land without the need to apply fertilizer and is not plagued by pests and diseases. The harvested hay can be easily made into fuel for power generation in the power plant using existing technologies.
