光质对北方地区全封闭阳台种植蔬菜植株形态建成的影响

从到达地球表面的太阳辐射、光与植物的形态建成、窗玻璃对透过其光照的影响、全封闭阳台特有的小气候效应等方面对北方全封闭阳台种植蔬菜的光形态建成作了细致的分析,阐明了蔬菜在此特殊小气候条件下容易徒长的根本原因,主要是封闭阳台的窗玻璃阻隔了大部分太阳光谱中的紫外线,尤其是具有使植株变矮效应的中波紫外线UV-B。

Effects of Light Quality on Photo Morphogenesis of Vegetable Cultivated on Closed Balcony in Northern Region

From the aspects such as solar radiation reached earth’s surface,plant photomorphogenesis,effect of window glass on transmitted light,microclimate effect of closing blacony,etc,the photo morphogenesis of vegetable cultivated on the closed balcony was analyzed in depth.Fundamental reason of excessive growth of vegetables in the special climate conditions was that the window pane of closed balcony blocked most of the ultraviolet rays in solar spectrum,especially ultraviolet B(UV-B) with the effect of dwarf plant.
