用杂交水稻作晚稻栽培是大幅度提高晚稻产量,实现晚稻超早稻的一项重要措施。我所大面积杂交晚稻连续两年一季亩产过《纲要》、超早稻,两季过“双纲”。泸县1978年栽插杂交晚稻38,900亩,平均亩产549.3斤,大大超过了该县双季晚稻的历史产量,接近早稻的单产水平。用杂交水稻作晚稻已成为各地提高晚稻产量的一项重要措施,改变了过去用常规稻作晚稻产量不高不稳的局面,受到了各级领导和广大群众的重视。 The cultivation of late rice with hybrid rice is an important measure to significantly increase the yield of late rice and realize the ultra-early rice in late rice. The large area of ​​hybrid late rice has been produced for one year in a row for two consecutive years. In 1988, planting of 38,900 mu of late hybrid rice in Luzhou County averaged 549.3 kg per mu, far exceeding the historical output of the double-season late rice in the county and close to the yield of early rice. The use of hybrid rice as a late rice has become an important measure to improve the yield of late rice throughout the country. It has changed the situation that the production of late rice with conventional rice was not stable and unstable, and was valued by leaders at all levels and the general public.
