Abstract: Kinds of organic matter were mixed in soil before tomato seedlings transplanted in Chinese solar greenhouse. The results showed that application of rice straw and puffed chicken manure mixed in proper proportion could increased the tomato yield significantly through improving the leave chlorophyll content , photosynthesis and carboxylation , as well as inhibiting respiration. The sustained decomposition of straw help maintain a higher CO2
concentration in the greenhouse air during five months of tomato growth stage. This can meet the needs of the tomato growth completely.

Key words: Tomato, Organic matter, CO2, Physiological effect
