The invention discloses a method for improving photosynthetic efficiency of plants, which comprises the following steps: inhibiting or knocking out bile acid sodium cotransporter genes in the plants,and simultaneously over-expressing glycollate dehydrogenase genes, glyoxylate carboxylase genes and tartronic semialdehyde reductase genes. The method creatively discovers that the expression of the BASS6 gene in the plant is inhibited, the overexpression of the glycollate dehydrogenase gene, the glyoxylate carboxylase gene and the tartronic semialdehyde reductase gene is combined in chloroplast,the photorespiration can be significantly reduced, the photosynthetic efficiency of the plant can be improved, the biomass or the yield of the plant can be increased, more importantly, the drought tolerance of the transgenic plant is significantly higher than the drought tolerance of the plant inhibiting the PLGG1 gene expression, and the biomass or the yield under the drought condition is increased by 3-45% compared to the non-transgenic control.
