在当前农村调整产业结构时期,粮食生产必须保持稳定增长。我省水稻是主要粮食作物,经1985年调整品种结构,发展优质稻米生产,对大面积栽培品种选优淘劣,使全省早稻中优质品种面积提高到占播种面积的50.5％,晚稻达80％,从而迈出了我省改善提高米质的第一步。很多地方由于良种更新更换及时,单产提高,总产增加。但也有少数地方,由于没有因地制宜,选用品种不当,招致减产。这些事实,再一次告诉我们,引种要通过试验试种,才有把握,盲目种植,就会给生产带来不应有的损失。引种
In the current period of adjustment of industrial structure in rural areas, grain production must maintain a steady growth. Rice in our province is the main food crop. After adjusting the variety structure in 1985, developing high-quality rice production, the selection of large-scale cultivated varieties is excellent and scouring poor, so that the area of high-quality varieties of early rice in the province is increased to 50.5% of the sown area, %, Thus taking the first step to improve the quality of rice in our province. In many places due to the timely replacement of improved varieties, improved yields and increased total output. However, there are also a few places that, due to the fact that they are not in line with local conditions, improper selection of varieties leads to a decrease in production. These facts tell us once again that it is only through grants of experiments that we must make sure that the introduction is carried out blindly and bring about undue losses to our production.
