Abstract
Sugar beet(Beta vulgaris L.) variety Nongdatianyan No.4 was chosen in this study.Under same condi-tions of field cultivation,the effects of spraying low concentration of NaHSO3 and KHCO3 on the leaves at growth stage were studied.As a result,we discussed the photosynthesis carbon metabolism,and the intrinsic mechanism of the development of root yield and sugar content.The results showed that during sugar beet growth different stage,spraying NaHSO3 and KHCO3 on leaves increased the net photosynthesis PEPCase and Rubisco activity,which might result in the increase of root yield and sucrose content of roots in the end,7.1%-23.2% and 10.5%-20.3% increase in root yield and sucrose content,respectively.However,the intercellular CO2 concentration and stomatal conductance of leaves showed an initial increase and then declined trend,indicating that the non-stomatal factor is the main reason for the difference in photosynthesis.
