文摘内容 The photosynthetically active radiation energy of the direct solar radiation,of diffused radiation and of global radiation were measured,and their diurnal variations,seasonal variations,regional differences and the impacts of meteorological factors on them were also analyzed.By the result of measurement combined with theoretical analysis climatological estimate formulas for the photosynthetically active radiation energy and photo-quantum flux density of the direct and the global radiation were proposed by the authors.
