Abstract:: Taking tomato cultivar ‘Jinguo No.1’ as test material，in order to study the growth rule and dry matter production and distribution of tomato plant in a solar greenhouse.The results showed that the plant height，leaf number，leaf areas and weight of total dry matter were linearly increased with the days after transplanted，which were 2.77 cm/d，0.3 leaf/d， 78.8 cm2/d and 9.12 g?m-2?d-1 ,respectively.Fruit dry weight and total dry weight of plant also showed linear relationship.Fruiting did not occur until plant dry weight reached to 42 g.And after fruiting，fruit dry weight increased about 0.7 g when total dry weight of per plant increased 1 g.Dry matter distribution proportion of root，stem and leaf declined obviously from plant flowering to fruiting，while the proportion of fruit dry weight was increased obviously，which the proportion was more than 60%.Dry matter production of tomato had a strong linear relationship with accumulated temperature，and normally dry matter production was increased about 0.67 g/m2 each effective accumulated temperature unit.Also，dry matter production of tomato plant had linear relationship with photosynthetic active radiation in the greenhouse.
