6、生长在中国。小时侯，他在学校读过书，得了个“问问题的学生”的绰号。袁隆平从小就对植物感兴趣。他在大学里研究农学。作为一个年轻的教师，他开始了作物育种的实验。他想，养活世人的关键是更快更好的生产水稻。他认为，唯一的办法是使不同种类的水稻杂交，这样就能产生比原先任何一种水稻产量都要高的新品种。首先，袁隆平对不同种类的水稻进行实验。1996年，他的研究成果在中国发表。接着他开始寻找一种特殊的稻种。这种稻种必须是雄性的，必须是不结果的。最后，在1970年，一种天然的雄性不育稻种被发现，这是一个突破性的发现。全国各地的研究者们被召集在一起开发新水稻种。研究得到了政府的赞助。由于袁隆平的发现，中国的水稻产量在20世纪90年代增长了47.5%。还有其他的益处，五万平方公里原来的稻田现在被用来种植蔬菜和其他经济作物。除此之外，袁隆平研制的水稻还出口到巴基斯坦和菲律宾等国家。在巴基斯坦，水稻是继小麦之后的第二种最重要的作物并将在许多地方种植。中国袁隆平高科技公司以开发出一种新的杂交水稻。这种杂交水稻的产量远高于巴基斯坦其他种类的水稻。
