在毛主席的革命路线指引下,在华主席的亲切关怀下,通过社会主义大协作和大搞群众运动,我国育成了杂交水稻,并迅速用于生产。这是继水稻品种高秆改矮秆之后,又一次重大技术改革。我区杂交水稻的试验试种工作,在区党委负责同志的重视和支持下,一九七三年实现“三系”配套后,各级领导和广大干部、群众积极试种。一九七四年晚造试种20亩,亩产1000斤;一九七五年早造试种77亩,亩产1002斤;晚造2300亩,统计1551亩,亩产 Guided by Chairman Mao’s revolutionary line and under the gracious care of Chairman Hua, China has bred hybrid rice through rapid socialization and mass mobilization, and has rapidly adopted it for production.
