摘要
光周期具有抑制苗木早期休眠,延长其生长期的作用,具有促进欧洲云杉苗木生长的作用,其在形态指标和生物量上表现得极显著。欧洲云杉大棚育苗补充光照的完整技术可采用整夜补光,随着光强度的增加,苗木生长形状各指标呈渐增的趋势。光质以白光较好。
Photoperiod has the impact of inhibiting early dormancy of seedling, prolonging growth time and accelerating growth of Picea abies seedling, which is extremely significant on the morphological index and biomass. The integrated techniques, of supplementing illumination on Picea abies breeding in plastic shed, was supplementing illumination at all night and use white illumination. The various indices of seedling growth figure were increasing gradually with the enhancement of illumination intensity.
