籼稻在我国的水稻生产中占有很重要的地位,其产量约占稻谷总产的四分之三.但目前大面积种植的早籼稻米品质远未达到人民群众的要求,多数品种米质不够理想。因此,调整品种布局,发展优质稻生产,现已成为农业领导部门、生产者和消费者的共同迫切要求。 Indica rice occupies a very important position in rice production in our country, and its output accounts for about three fourths of the total output of rice. However, the quality of early indica rice grown in large areas is far from meeting the requirements of the masses and the quality of most varieties is not ideal . Therefore, adjusting the variety distribution and developing high-quality rice production have now become the common urgent requirements of the agricultural leaders, producers and consumers.
