摘要
茉莉在中亚热带气候类型的温州地区,年发梢4～5次,开花3～5次。茉莉花序属聚伞花序,花期物候可分为:花芽膨大期、露萼期、伸冠期、露白期、初花期、盛花期和谢花期。其中露白期是花蕾采摘的最佳时期,盛花期是加工最适期。7年的采花量与气象观测资料分析表明,花期早晚、开花频次及历时长短均与当年气候条件,特别是与花期的积温有关。
Jasmine inflorescence is of scorpiod。7 Years' meteoro-logical observation showed that the du- ration of the blooming period and frequency of jasmine were closely related to the climatic factors,esp。 to the temperature summation prior to the blooming time。Scientific observation and analysis on meteoro- logical records indicated that the growth of jasmine might be phenologicaly divided into 7 stages,and the appropriate stahge was most suitable for flower harvesting,the late flower bud stage for flower plucking, and pre-full blooming stage for processing。
