Abstract

The effects of collocation of different fertilizers on photosynthesis characteristics of Stevia rebaudiana Bertoni were studied in the open field of Qingdao Agricultural University. The results indicated that the chlorophyll content and net photosynthetic rate of the fertilizer treatments were higher than that of no fertilization (CK), and concentration of intercellular CO₂ of the fertilizer treatments was lower than CK. The indicators on chlorophyll content, net photosynthetic rate, and stomatal conductance of organic fertilizer treatments before 60 days after transplanting were lower than fertilizer treatment. And after 60 days after transplanting, organic fertilizer treatment on these indicators was higher than that of ck. And the concentrations of intercellular CO₂ of organic fertilizer and decomposed S. rebaudiana Bertoni leaf (t₄) were lower than others. The effects of collocation of different fertilizers on photosynthesis characteristics of S. rebaudiana Bertoni were studied in the open field of Qingdao Agricultural University.
