1 确定再生稻的适宜种植区域再生稻主要是在双季稻温光条件不足、种一季稻温光又有余的地区和部分双季稻区发展。再生稻能否种植,必须根据当地的自然气候条件结合杂交组合再生稻的生育特点来确定。凡组合所需的安全生育天数、积温和某一地区所提供的热量条件相吻合,该地区就可以蓄留再生稻。根据各地经验,一般年均温18℃以上、
1 Determine the Suitable Planting Area for Ratooning Rice ratooning rice is mainly developed under the conditions of insufficient light and temperature of double cropping rice, more than one light and one more season of double cropping rice and some double cropping rice. Whether or not ratooning rice can be planted must be determined according to the local natural climatic conditions and the characteristics of reproduction of ratoon rice. Where the combination of the required number of days of fertility, accumulated temperature and heat conditions in a given area coincide, the area can be stored ratooning rice. According to local experience, the average annual average temperature above 18 ℃,
