Abstract: A field experiment was carried out to study the effects of CO2 enrichment by fermentation of organic wastes (rice straw and organic fertilizer) on the growth, yield and quality of cucumber in greenhouse. The results showed that CO2 enrichment by fermentation could increase average CO2 concentration 2.6 times and raise daily average temperature 1℃, meanwhile, cucumber growth, yield and quality also significantly increased, resulting in 25.13% productivity raised and 8 days ahead of marketing time. Furthermore, the morbidity of angular leaf spot of cucumber and leaf disease index decreased by 12% and 23%, respectively.

Key words: organic wastes, fermentation, CO2 enrichment, cucumber
