摘　　要：温度是影响作物发育速度的基本因子之一，温度的高低决定生育期的长短。利用全国水稻生态试验资料，分析了不同气候带的水稻生育期与温度的关系。结果指出，水稻生育期平均气温升高１℃生育期日数平均缩短７．６日．温室效应使气温升高１～４℃，将导致我国各地水稻的一季稻和早稻生育期缩短；东部地区目前的生育期等日期线北移：东北地区北移１～５个纬度；黄淮地区北移３～６个纬度，通过调整种植季节，选用合适的水稻生态父型，以水调温措施，可以减少生育期缩短的日数。Temperatu re is cne of basic factors to influence the growtii and development ofcrops,and decides the length of growing period。The relationships between the length ofrice growing period and temperature are a nalysed by using data of rice ecologicalexperiYI1ent.The resuitsehow that during rice growing period,when mean temperaturerises 1℃,the days of growing period deerease 7.6 day Aecording to experts’prediction,air temperature will rise 1～4℃,due to warn1ing climate,which makes thegrowing period of single cropping rice d,nd early rice in China sherten. The isogram of the date of growing period in the eastern China will remove northwards,1～5degreeslatitude in Nortbeast China,3～6degrees in the Huang-Huai-Hai Plain。The growingperiod’s getting shorter can be mitigated by taking following measures;adjusting theplanting season,selecting appropricte rice ecological types and regulating temperetturewith water.
