The treatment and discharge of wastewater from natural rubber processing was an urgent practical problem to be solved in the natural rubber processing industry. It had high production application value to explore the fermentation effect of different bacterial agents on wastewaterfrom natural rubber processing and utilize them resourcefully. In thisstudy，four different treatments of natural rubberwastewater i.e. without addingbacteria，adding Bacillus subtilis，adding Actinomycetes， adding Aspergillus niger and a control group of clear water and compound fertilizer were setup，and a pot experiments was conducted to further study the impact of different fermentation liquids on thegrowth，quality and physical and chemical properties of Pak Choi. The results showed that the fermentation effect of adding Aspergillus niger wasthebest，followed by Bacillus and Actinomycetes. Different treatments of fermentation liquid irrigation had good effects on the growth quality ofChinesecabbage，of which the effect of adding Aspergillus niger and actinomycetes fermentation wasthebest，followed by adding bacillus. The soil porosity increased with the addition ofmicrobial agents，and the average value was 1.76% higher than that of the water control. The addition of Aspergillus niger fermentation broth had the highest increase in soil porosity.Compared with the watercontrol，thesoil pH and organic matter content increased by 0.33% and19.2%，respectively，after irrigation with Aspergillus niger fermentation broth. To sumup，adding Aspergillus niger has the best effect on the growth and quality of Chinese cabbage and has no effect on soil porosity.
