我省从1976年开始试种杂交水稻,三年来示范面积迅速扩大,今年全省种植四万多亩,一般比常规稻增产2——3成。为了迅速推广杂交水稻,现对我省当前发展杂交水稻中的几个技术问题提出几点意见。一、明确骨干品种,选配好组合近几年来,我省各地各级科研、农技、种子部门,从兄弟省区引进了大量的 The province began experimenting with hybrid rice in 1976, and the demonstration area has rapidly expanded in three years. The province plans to plant more than 40,000 mu this year, generally increasing yields by 2-3% over conventional rice. In order to promptly popularize hybrid rice, a few suggestions are put forward on several technical problems in the current development of hybrid rice in our province. First, a clear key varieties, a good mix of options In recent years, our province at all levels of scientific research, agricultural technology, the seed sector, from the brother province introduced a large number of
