在闽北单双混作区,利用光热条件种双季稻不足一季有余的耕地发展再生稻生产,是大幅度提高耕地单位面积产量的有效措施。头季稻与再生稻密切相关,是再生稻的基础,要取得再生稻高产,必须走好三步：一是种好头季稻,取得头季稻高产,二是获得高质量的稻桩,三是管好再生季。%Ratoon rice production is an effective measure for increasing yield per arable land area at the mixed single and double cropping rice areas of North Fujian which light and temperature conditions were not sufficient in double cropping rice farming but a remainder for growing single cropping rice.The first crop rice had a close correlation with ratoon rice and was also the base of ratoon rice.Therefore,to improve high yield of ratoon rice,we must take three steps:(1)to obtain high yield of the first crop rice by excellent cultivation techniques,(2)to reserve high-quality rice stubbles,and(3)to manage the second crop of ratoon rice.
