摘  要:
以内丘县1960~2013年日最高气温、日最低气温、初终霜日期、无霜期数据为依据,采用统计分析和滑动t检验方法,针对晚霜冻对内丘富岗苹果的影响进行分析。结果表明,内丘县终霜平均日期为3月30日,无霜冻期平均为206 d;近年来内丘县无霜期呈现明显增加的趋势,且富岗苹果花芽萌芽期和盛花期发生大面积冻害的有6年,这6年基本上均是受强冷空气的影响,降温幅度大,日最低温度、日最高温度在晚霜冻发生前呈现阶梯式下降、在晚霜冻发生后呈阶梯式上升,这为晚霜冻的预警和预防提供了准备时间。

摘  要:
Based on daily maximum temperature,daily minimum temperature,the beginning of the last frost date,frost free period data in Neiqiu County during 1960- 2013,using statistic analysis and moving t method,effects of late frost on Neiqiu Fugang apple were analyzed. The results showed that last frost data is on March 30,frost free period data is 206 d; in recent years,frost free period showed obviously increasing trend; there are 6 years of large area chilling in apple flower germination period and full- bloom stage,daily minimum temperature and maximum temperature indicated ladder type decreasing and increasing before and after late frost,which provides preparation time for early warning and prevention of late frost.
