本文就再生稻在我区的发展前景进行讨论和提出建议。我区水稻种植面积近300万亩,其中双季稻约180万亩,单季稻面积120万亩左右。其中海拨600M以下的约占90万亩左右,如果有60万亩改为“中稻——再生稻”比单晚每亩净增150——200公斤计算,每年即可净增稻谷9——12万吨。我区在五十年代至七十年代曾小面积试种再生稻,大多获得成功。未能大面积推广,其主要原因:(1)留桩较低,夏季水温高,水层控制不好易造成烫芽死苗缺丛;(2)由于留桩较低,不易做到平割,斜割再生稻出穗不 This paper discusses the prospects of ratooning rice in our region and puts forward suggestions. Rice planting area in our region nearly 300 million mu, of which about 180 million mu of double-cropped rice, single-season rice area of ​​120 mu. Among them, about 600,000 mu of seabed is about 90 million mu. If there are 600,000 mu, it will be changed to “middle rice - ratoon rice” by a net increase of 150-200 kilograms per mu per night. 120,000 tons. My area in the 1950s to the 1970s had a small area planted ratooning rice, most of them succeeded. The main reasons are: (1) low left pile, high summer water temperature and poor control of the water layer, which may result in the shortage of scalping buds; (2) due to the low pile retention, it is not easy to cut flat , Oblique cut ratooning rice is not
