在毛主席革命路线指引下,各级委党加强领导,发动群众大搞科学实验活动,我地区水稻杂种优势的利用,取得了可喜的成果。一九七三年“三系”配套成功之后,我地区陆续推广种植了南优、银优、汕优、矮优、朝优、金优、常优、四优等组合。去年杂交水稻发展到一百八十万亩,其中早造七十多万亩,平均每亩比常规品种增190斤,晚造南优组合占全地区杂交水稻种植面积的百分之八十左右,大部分社队获得大幅度增产。 Guided by Chairman Mao’s revolutionary line, the party committees at all levels have stepped up their leadership and mobilized masses to engage in scientific experiments. The utilization of rice heterosis in our region has yielded gratifying results. After the successful completion of the “three lines” in 1973, a number of combinations including Nam You, Yin You, Shanyou, Dai You, Chaoyou, Jin You, Chang You and Si You were successively promoted in our region. Last year, the hybrid rice developed to 1.8 million mu, of which more than 700,000 mu have been made as early as 190 kg more per mu than the conventional varieties, and late Nanami combinations have accounted for about 80% of the acreage of hybrid rice in the entire region , Most of the communes and brigades got a substantial increase in output.
