In order to screen out the bio-organic fertilizer with high growth-promoting ability for coriander，taking coriander as the research object，five treatments of chemical fertilizer(CK)，organic fertilizer(OF)，Bacillus subtilis bio-organic fertilizer(BF1)，Saccharomyces cerevisiae bio-organic fertilizer(BF2)，Pichia pastoris bio-organic fertilizer(BF3) were set up under equal nutrient conditions for pot experiment. By studying the growth index of coriander，soil physical and chemical properties and enzyme activity，the bio-organic fertilizer with the best growth-promoting effect was selected. Compared with CK，the biomass，shoot fresh weight and root fresh weight of coriander treated with BF1，BF2 and BF3 increased significantly by 13.12%–35.95%，16.36%–41.8% and 4.74%–20.86%，respectively，and the biomass of BF3 treatment was the highest. The treatments of BF1，BF2 and BF3 significantly increased the root activity，root length，root volume，root surface area，root tip number，root diameter and plant nutrient content of coriander，and effectively promoted the growth and differentiation of root system and nutrient absorption of coriander. The BF1，BF2 and BF3 treatments improved soil physical and chemical properties and enzyme activities. Soil electrical conductivity decreased by 19.43%–24.02%，organic matter increased by 44.20%–66.18%，alkali-hydrolysable nitrogen increased by 17.12%–28.17%，available phosphorus increased by 30.40%–48.83%，available potassium increased by 4.49%–9.27%，soil urease activity increased by 2.80%–5.82%，soil acid phosphatase activity increased by 11.90%–30.25%，and soil sucrase activity increased by 21.71%–28.45%. Redundancy analysis showed that the changes of root tip number and root surface area were the main reasons affecting the growth and nutrient absorption of coriander. Through the principal component analysis of the growth characteristics of coriander，it was concluded that BF3 treatment had the best growth-promoting effect. The treatments of BF1，BF2 and BF3 could improve soil fertility and enzyme activity，increase root activity，improve root morphology and promote growth of coriander. Among them，BF3 treatment had the best growth-promoting effect and had the potential to develop into a high-quality growth-promoting bio-organic fertilizer.
