摘　　要：介绍了湖北省再生稻发展的现状及潜力,种植面积在3.3万hm2左右,再生季产量4 500 kg/hm2左右,全省适宜发展再生稻的有效耕地面积在50.0万hm2以上,开发利用其中七、八成每年全省即可增产稻谷15亿～20亿kg.The development status of ratoon rice in Hubei province was introduced.Ratoon rice planting area was about 33 thousand hm2 and its yield was about 4 500 kg/hm2.The potential for expanding ratoon rice in Hubei province was analyzed.There were more than 500 thousand hm2 arable area suitable for planting ratoon rice.If 70～80 per cent suitable areas were exploited to plant ratoon rice in Hubei province,the total rice yield would increase about 1500million～2 000million kg annually.
