Abstract：The effects of common soil cultivation applying CO2 and organic soil cultivation on yield and nutrient quality of cucumber （Cucumis sativus L.）in solar greenhouse were studied，and the CO2 concentrations under two cultivation patterns were compared at the same time．The results showed that common soil cultivation applying CO2 and organic soil cultivation could all increase CO2 concentration in greenhouse in the morning，and the CO2 concentrations in treatment were much higher than that in common soil cultivation control（PCK）during the sunny morning，which made the cucumber growth better than PCK．Physiological analysis indicated that common soil cultivation applying CO2 and organic soil cultivation could all increase the chlorophylls contents of cucumber leaf blades，root system activity and plant net photosynthetic rate．In applying CO2 treatment，the soluble solide and VC contents of cucumber were significantly increased by 10.21% and 7.23%，respectively，than that of common soil cultivation control．The contents of total sugar and crude protein in organic soil were significantly higher than the other treatments．Applying CO2 could improve cucumber yield and the single plant yield was significantly higher than that of PCK，similar to that of organic soil cultivation．Applying CO2 treatment on yield was mainly in the middle and later stage of harvest，whereas the effect of organic soil cultivation on yield was mainly in the early and middle stage of harvest．The organic soil cultivation can not only improve root zone environment，but also increase the CO2 concentration in greenhouse．Thus we can achieve high yield and high quality without applying CO2.
