Abstract: An interplanting experiment of Taxus cuspidata and Ficus carica under indoor control conditions was designed and compared with the single plantation of T.cuspidata and single planting F.carica. The differences in growth indexes, photosynthesis, and soil enzyme activities of T.cuspidata and F.carica were investigated, respectively. The results were as follows:①In terms of growth, the growth rate of interplanting T.cuspidata for 3 months was 152.6%, which was 1.56 times the growth rate of single planted T.cuspidata. The biomass of interplanting F.carica for 3 months in the same year was 68.4 cm3, which was 36.3% higher than that of single planted F.carica. ②In terms of photosynthesis, the net photosynthetic rates of interplanting T.cuspidata and F.carica for 3 months were increased by 19.0% and 5.3%, respectively, compared with the corresponding single planting species at the light intensity of 800 μmol·m-2·s-1. ③In the interplanting T.cuspidata and F.carica mode in July, the activities of sucrase, urease, and acid phosphatase in soil were 51.6%, 58.5%, and 50.8% higher than the corresponding enzyme activities in the soils planted with single Taxus cuspidate mode, 85.5%, 47.5%, and 71.9% higher than the corresponding enzyme activities in the soils planted with single F.carica mode. There was no significant difference in soil polyphenol oxidase activity between different planting modes(P>0.01). In conclusion, the interplanting of T.cuspidata and F.carica can increase soil sucrase, urease and acid phosphatase activities, and promote the growth of both plants.
