在经过两年多时间的努力之后 ,我国科学家又育成一种新型超级稻。它的大面积推广 ,有望使超级杂交稻生产彻底告别“92 0”,达到降低成本、稳产增产、减少污染的理想目标。2 0世纪以来 ,水稻已完成了从高杆到矮杆 ,从矮杆到杂交的两次飞跃。中国在这一领域一直居于世界领先地位 After more than two years of hard work, our scientists have developed a new type of super rice. Its large-scale promotion is expected to make a farewell “92 0” of super hybrid rice production, achieving the ideal goal of reducing costs, steadily increasing production and reducing pollution. Since the 20th century, rice has completed two leaps from tall poles to short poles and from short poles to hybrids. China has always been the world leader in this field
