By means of applying liquid CO2 fertilizer,effects of CO2 fertilizer on photosynthesis and yield formation of solanaceous fruits Vegetables were conducted in protected field,and the relation between CO2 and photosynthesis,the hypothesis of CO2 fertilizer increasing yield and the noticeable items of applying liquid CO2 fertilizer were discussed.The results indicated that: 1) Application of liquid CO2 fertilizer,the survival environment of solanaceous fruits vegetables in protected fields was improved,leaf photosynthesis was strengthened very significantly and physiological metabolic functions of solanaceous fruits vegetables were promoted.2) Application of liquid CO2 fertilizer,the growth and development or yield traits of solanaceous fruits vegetables were promoted very significantly and yield formation was very notably or notably increased.3) The responses of different solanaceous fruits vegetables to CO2 fertilizer were different,the order of sensitive response was hot pepper eggplant tomato.4) The responses of different growth and development and yield characteristics of solanaceous fruits vegetable to CO2 fertilizer were also different,generally,the characteristics of cell elongation and longitudinal growth were more sensitive than that of cell hyperplasia and lateral growth(such as leaf width).
