根据2006—2012年白玉兰、日本东京樱和早银桂花期资料和同期气象资料,分析了影响花期的主要气象因子。结果表明:(1)影响白玉兰初花期早晚的主要气象因子依次是温度、日照、降水,且以冬季和冬末春初的因子关系较为密切,冬末春初至开花的气温回升速度也是影响花期早晚的重要因子之一;(2)上年12月到当年2月期间的气温高(低)导致东京樱初花期早(晚),雨日多(少)则东京樱初花期早(晚);(3)最低气温5天滑动平均≤23℃首日早则早银桂初花期也早,5日滑动平均最低气温≤23℃首日前10天降水多、相对湿度大有利于初花期提早。
Based on the data of Magnolia grandis from 2006 to 2012, osmanthus fragrans from Tokyo, Japan, and Japan, and the meteorological data of the same period, the main meteorological factors influencing flowering were analyzed. The results showed as follows: (1) The main meteorological factors influencing the early and late flowering stage of Magnolia grandiflora were temperature, sunshine and precipitation. The relationship between winter and late spring was close, (2) the high (low) temperature during the period from December last year to February of the previous year resulted in the flowering of early flowering (late) (3) The minimum temperature of 5 days sliding average of ≤ 23 ℃ on the first day as early as early Silver Gui flowering early, minimum 5 day sliding temperature ≤ 23 ℃ 10 days before the first day of precipitation and more relative humidity is conducive to early flowering early.
