The results showed that the sunlight duration in tomato plant in solar greenhouse in winter was few. The total solar radiation above tomato plant canopy differed obviously between seasons . The solar radiation within the plant population of tomato was affected by sea- son , density and plant height si multaneity , with the solar radiationin spring being remarkably higher than that in winter and that above plant being remark- ably higher than that below plant in the same season . The bigger the density was , the poorer the sunlight environment within plant population was . The sunlight duration , total solar radiation above tomato canopy and plant population structure of tomato i ncl uded plant height ,density etc . were the key factors affecti ng sunlight environment of to mato .
