袁隆平,男,1930年9月出生于北京,1953年畢業(yè)于西南農(nóng)學院農(nóng)學系。畢業(yè)后,一直從事農(nóng)業(yè)教育及雜交水稻研究。在中國人民正鬧饑荒的20世紀60年代,袁隆平提出了雜交水稻的概念,這種新型水稻具有高產(chǎn)量的特點。10年后,他研制成功了一種產(chǎn)量比一般水稻高出30%的新型水稻。袁隆平一生獻身于農(nóng)業(yè)研究,先后受到聯(lián)合國教科文組織、糧農(nóng)組織的稱譽。袁隆平雖已年屆70歲,仍然一如既往地從事農(nóng)業(yè)研究。袁隆平人物簡歷APIONEERFORALLPEOPLEReadingScanning:Findoutthemainideaofeachparagraph.DrYuan’sbiographyDrYuan’sappearance
