产量。杂交作物的一个特点表明，它们可以获得比传统作物更高的产量。通过极大的努力，袁隆平克服了巨大的困难，培育出了第一代杂交水稻，使农民能够大幅度提高（水稻的）产量。据估算，现在中国国内大约60%

的大米消费是由袁隆平的杂交品种

形成的作物组成的。在内心深处袁隆平仍然还是一个纯粹的农民。作为一个土地之子，他不在乎名誉和金钱。袁隆平虽然很富有，却没有过悠闲的生活。他的设想是，他想象水稻植株像高粱一样高，每支稻穗像扫帚一样大，每粒稻米像花生一样大。他最近提出的在盐碱地种植水稻的愿景也已成为现实。Farmersprefer

肥而不是有机肥。但是用化肥种植的作物缺乏营养、必需的

矿物质和美味。今天，化学

农药已在农业中得到了广泛的应用。农药可以杀死有害的细菌和昆虫，但也会损害有营养的作物。这反过来又影响到消化它们的动;l;,l/ikk/;ipop物和人类。现在大多数国家都已禁止使用某些杀虫剂。作为替代，一些农民已经转向有机农业，因为有机蔬菜和粮食在城市的

杂货店里很受欢迎。这些农民还更换作物。例如，他们一年在一块地里种玉米或小麦，下一年在那里种豆类。这些作物的根
