盆栽菊花反季节开花调控技术研究

Research on Anti-seasonal Flowering Control Technology of Potted Chrysanthemum

为筛选适合北京地区春季开花的菊花品种,建立并推广菊花反季节栽培技术,本文以117个优良盆栽菊花品种为试材,采用温室盆栽方式,研究了盆栽菊花反季节栽培技术。通过试验确立了盆栽菊花反季节生产的日程安排;从光照、温度、浇水、施肥和病虫害防治等方面总结了反季节栽培中的技术要点;实现了所有供试菊花品种均在翌年4-5月陆续开花,达到了反季节开花的目的;筛选出20个利于反季节栽培并推广的优良盆栽菊花品种供北京地区春季生产用花。

In order to select suitable chrysanthemum cultivars for spring blooming in Beijing,establish and promote chrysanthemum anti-season cultivation technology.Then 117 excellent pot chrysanthemum cultivars were used and study potted chrysanthemum anti-season cultivation technology by greenhouse potted methods.According to test established the schedule for the anti-season production and summarized the technical points of anti-season cultivation from the aspects of light,temperature,watering,fertilization and pest control;all chrysanthemum cultivars were bloom in April-May of the following year and has achieved the purpose of anti-season flowering;20 excellent pot chrysanthemum cultivars that are conducive to anti-season cultivation and promotion were selected to provide reference for subsequent spring flowers in Beijing.
