在生产上应用的杂交水稻,是属于中籼类型的组合。现在还没有适合我省双季稻地区种植的晚粳组合,而是利用这些中稻组合来作双季晚稻栽培的。1976年我省种植杂交种双季晚稻(简称杂交双晚,下同)3万余亩,仅公安县就种了4,800亩,普遍获得了丰收。生产实践表明,在同等的生产条件下,杂交双晚可比普通晚粳品种增产2—3成,较易于夺取超《纲要》,上千斤的产

The hybrid rice used in production is a combination of middle-type indica rice. There is no suitable japonica rice combination for double-cropping rice in our province. Instead, these mid-rice combinations are used for cultivation of double-cropped late rice. In 1976, more than 30,000 mu of double-cropped late hybrid rice was planted in the province in our province (abbreviated as hybrid double nights, the same below), and only 4,800 mu of seedlings were planted in Gong’an County, with a general good harvest. Production practice shows that under the same conditions of production, double late hybrid rice yield can be 2-3% higher than the average late japonica rice varieties, more easy to capture the super “outline”, the kilogram of production
