31、读于重庆西 南农学院。 39 返返 首首 页页 1953 年毕业后，他从事研究工作。袁隆平意识到，更多的耕地并 不是解决问题的办法。农民们需要增加他们现有土地上农作物的产量。 如何做到这一点在当时是一个具有挑战性的问题。袁隆平确信，答案可 以在杂交水稻的培育中找到。 杂交作物是一个物种的两个或两个以上变 种的杂交。 杂交作物的一个特点是它们的产量通常比传统作物高。 然而， 是否有可能培育出一种自花传粉的杂交植物，如水稻，这是一个有很大 争议的问题。当时人们普遍认为这是不可能的。通过不懈的努力，袁隆 平克服了巨大的技术难题，于 1974 年培育出了第一种可用于农业生产 的杂交水稻。这种杂交水稻使

32、农民大大增加了产量。 40 返返 首首 页页 据估算， 现在中国国内消费的大米有大约百分之六十来自袁隆平 的杂交水稻， 他的杂交水稻品种让中国农民每年能够生产出大约两亿 吨大米。 袁隆平的创新不仅帮助养活了中国， 也养活了许多其他依赖 大米的国家，如印度和越南。因为他的不可估量的贡献，袁隆平在国 内外获得了无数的奖。 41 返返 首首 页页 考虑到杂交水稻使袁隆平变得相当富有， 人们可能认为他会退休 享受闲适的生活。然而，事实远非如此。事实上，袁隆平在内心深处 依然是一个农民。作为一个农民，他不太在乎名声和金钱。相反，他 大量捐款以支持农业研究。 42 返返 首首 页页 袁隆平最让人印象深刻的是他不断实现梦想的能力。很久以前， 他设想了一种像高粱一样高的水稻， 每一穗米都像扫帚一样大， 每一 粒米都像花生一样大。 他成功地培育出一种可以养活国内外更多人的 水稻，他对“海水水稻”的最新设想也已成为现实，并可能在中国开 辟近 100 万平方公里的盐碱地，用于水稻生产。尽管年事已高，袁隆 平的内心仍然年轻， 充满了远见， 每个人都在等着看他下一步的梦想。 43 返返 首首 页页 Thank you for watching ! 44
