| 摘 要： | 通过设置田间与气象台站对比气象观测,对长乐市冷空气过境后的晴冷天气(易发生霜冻天气)的极端最低气温进行差值订正,将田间寒、冻害气象指标订正为气象台站预警阈值指标,提出预警方法。并采用福建省长乐市气象站近30年的气象观测数据(1982-2011年)分析马铃薯寒、冻害时间分布特征,总结避冻栽培策略。

| Abstract: | The difference of the extreme minimum temperature was revised by setting the field meteorological observation contrasted with the meteorological station in sunny cold weather （frost-prene） following the cold air. The meteorological indicators of freezing observed in the field was revised into the early warning thresholds of meteorological stations, the wanting method was accordingly proposed. The meteorological observation data in three decades from 1982 to 2011 in Changle City Meteorological Station, Fuzhou were taken to analyze the temporal characteristics of freezing hazards in potato, so as to work out the measures to avoid the freezing hazards. |
