摘要: 研究了有机质配施对温室内CO2 浓度变化以及番茄的生理效应的影响。结果表明, 稻草和膨化鸡粪按适当比例配合撒施处理可以提高叶绿素含量, 增强光合, 抑制呼吸, 加快羧化, 从而显著提高产量。同时证实了由于稻草的持续分解, 使得温室内的CO2 在生育后期仍然能保持较高浓度, 可以满足长节栽培条件下番茄生长发育对CO2 的需求。

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
