摘要: 利用长武县苹果物候观测资料和相应气象资料分析了温度对苹果初花期的影响,主要结论为:(1)当日平均气温为10℃左右时苹果开始进入初花期;(2 )用“定日逆序的积温”法研究得出:苹果初花期早晚与上年冬后的积温有负相关关系,其中与当年春季以来≥5℃积温关系最密切;(3)用“非定日逆序的积温”法研究得出:与花前2 6 6 - 2 77天(上年7月中下旬前后)的逆序积温有极显著的负相关关系,相关系数较稳定

Abstract: The blooming time is sensitive to the meteorological conditions. By analyzing the observation data of meteorology and phenology of Malus in Changwu county, Shaanxi province, during 1995-2002, the results showed that:(1)the early blooming period started when daily average temperature accessed to 10℃;(2)there was a positive relationship between the early blooming time and the accumulated temperature (≥5℃) from spring, and the maximum coefficient appeared 14 days beforeblooming; (3)there was a significant negative relationship between the early blooming time and 266-277 days before blooming, and the coefficient was relatively stable, so it could be suggested as an approach for forecasting blooming time.
