| 摘 要： | 为了探明气候变暖对成都市水稻安全播种期及农事生产的影响,选取成都市13个气象观测站40年(1970-2009年)的逐日温度资料和3个农业气象基本站的水稻生育期观测资料,采用数理统计方法研究了温度变化和气候变暖对成都水稻安全播种期的影响。结果表明:自1976年以来,成都市的年平均温度基本上是3年为一振动周期,1996年开始,年平均温度和3月平均温度升高,水稻生长季延长。结合10℃、12℃初日到来时间和水稻抽穗扬花期及灌浆期的温度要求分析得出,成都中部地区的水稻安全播种期由原来的清明前后提前到3月27日,南部地区提前到3月24日,北部地区提前到3月31日。

| Abstract: | The daily temperature data from 13 meteorological stations during 1970-2009 and the data of rice growth period from three agricultural meteorological stations in Chengdu were analyzed to study the influence of climate warming on safety sowing time of rice in Chengdu.The results showed that there was a three-year vibration period in annual average temperature after 1976.The annual average temperature and average temperature in March has increased obviously since 1996,which results in prolongation of rice growth period.According to the first day with steadily over 10℃ and 12℃ and the climate condition for rice heading and flowering stage,and grain filling stage,the safety sowing time of rice in the central area,southern area and northern area should be on March 27,March 24 and March 31 respectively. |
