【摘要】 探究影响干旱地区玉簪花密度、花期和种子萌发特性的主导因素,为干旱地区玉簪的应用推广,花量和花期调控提供参考依据。本研究通过对乌鲁木齐市植物园内的玉簪物候观测,测定记录不同花密度的玉簪地的株高、冠幅、叶长、叶宽,叶片数、叶绿素含量等指标,得出影响玉簪花密度和花期长短的主导因素。结果显示:玉簪的开花性状受到植株的营养生长性状影响,其中株高大小是玉簪生长性状最主要的量化指标。花密度大小和花期长短都随株高增加呈现先上升后下降的趋势,要使每平米花密度达到最大,株高平均高度69.49cm,要使花期达到最长31天,株高平均为75.18cm。更多还原

【Abstract】 The key factors affecting flowering density,flowering period of Hosta were explored in order to provide a reference for the application and regulation of flower quantity and flowering period in arid areas.In this study,nutritional growth and flowering traits of Hosta were measured including plant height,crown width,leaf length and width,number of leaf blades,chlorophyll content,average daily light intensity,soil moisture and conductivity.The results showed that the flowering traits of Hosta were affected by the nutritional growth traits of the plant,in which the plant height was the most important quantitative index of the growth traits of Hosta.The flower density and flowering period showed a trend of increasing and then decreasing with the increase of the plant height.The conclusion was reached that the averange height should be 69.49cmin order to maximize the flower density per square meter,and the averange plant height should be 75.18cmin order to make the flowering period reach a maximum of 31 days.更多还原
