Abstract：This research focuses on the effects of different levels of microorganism agent-Zhibaokang on the growth, nitrate content, nutritional quality of Brassica campestris L. ssp. chinensis（L.）Makino var. communis Tsen et Lee and soil condition. Results showed that microorganism agent had significant effect on the leaves number, maximum leaves area and yield of Brassica campestris L. ssp. chinensis（L.）Makino var. communis Tsen et Lee,especially at a concentration of 22.5 kg?hm-2 level, and the plant had the lowest nitrate content at 22.5 kg?hm-2 level. But for the content of VC, 15.0 kg?hm-2 level was the highest. Furthermore, the soil salt content was reduced and the microbial number increased significantly with the addition of microorganism agent-Zhibaokang. In conclusion, microbial agents at concentration of 22.5 kg?hm-2 level has the optimal economic effect.
