Abstract：This paper studies the effects of temperature and light conditions of solar energy greenhouse on tomato（Lycopersicon esculentum Mill.） growth and fruit inflation by dynamic observation on temperature and light conditions and tomato growth status in early spring. The results showed that daily and night average temperatures，and shallow ground temperature during tomato vegetative growth period（ mid March） under solar cultivation could effectively reflect the dynamic changes of tomato leaf area，stem thickness and plant height，while the light radiation quantity and day/night average temperature differences had fewer influence on the above mentioned items. In mid April，when tomato fruit is inflating，the daily average temperature，accumulative temperature of lighting time calculated by hour，and solar radiant quantity had extremly significantly positive correlation with tomato fruit inflation. The stem thickness and leaf area had extremly significantly positive correlation with fruit inflation. This improves the establishment of source-pool rela tionship during fruit inflation.
