杂交水稻是我国在国际上一项有影响的农业科研成果。我省于1975年开始试种,在连续两年取得成功的基础上,1977年推广170多万亩,一般增产二、三成。1978年推广457万多亩,其中作中稻栽培的191万亩,亩产689斤,比全省中稻平均单产稍低;作晚稻栽培的266万亩,亩产546斤,每亩约增产150斤。1978年我省杂交水稻增产幅度比1977年小,也不平衡,出现了部分单位增产
Hybrid rice is an influential agricultural research achievement of our country in the world. In 1975, the province began trial planting. On the basis of two consecutive years of success, more than 1.7 million mu were popularized in 1977, generally increasing the output by 20% to 30%. In 1978, a total area of 4.57 million mu was popularized, of which 1.91 million mu was for middle-crop cultivation, 689 kg per mu, slightly lower than the average yield of middle rice in the province; 2.66 million mu for late rice cultivation, 546 kg per mu and about 150 kg per mu . In 1978, the yield increase of hybrid rice in our province was smaller than that in 1977, and it was also unbalanced. There were some units that increased production
