摘要: 为探索南充各地近34年水稻抽穗扬花期高温热害的影响及时空分布特征,笔者利用南充所辖7个国家气象观测站1981—2014年的地面观测资料和水稻生育期观测资料进行了研究分析。研究表明:南充各地的水稻抽穗扬花期主要集中在7月中旬至8月上旬;近34年水稻抽穗扬花期仪陇的高温热害最轻,市辖三区的高温热害最重,其次为营山、蓬安,再次为西充、南部,最后为阆中;近34年南充各地水稻抽穗扬花期高温热害以轻度为主,其次是中度,最后是重度;近34年南充各地水稻抽穗扬花期高温热害有明显加重的趋势,尤其要加强对市辖三区水稻抽穗扬花期高温热害的监测。

Abstract: The paper aims to explore the effect to Rice in heading and flowering period and the temporal distribution characteristics of Nanchong in the past 34 years, the author uses the ground observation data and the rice growth stage observation data from 1981 to 2014 of the seven national weather stations of Nanchong to research and analyse. The results showed that: the rice heading and flowering around Nanchong mainly in mid-July to early August; in nearly 34 years, the lightest heat damage to rice in heading and flowering period was found in YiLong, but the heaviest heat damage to rice in heading and flowering period was found in three municipality district, the second were YingShan and PengAn, again were XiChong and NanBu, finally was LangZhong; although, most of time, minor heat damage to rice in heading and flowering was found in the past 34 years, followed by moderate and severe finally; in nearly 34 years, the heat damage to rice in heading and flowering period have obvious increase trend, especially should strengthen the monitoring of the heat damage to rice in heading and flowering period in the three municipality district.
