Abstract
Effects of nanoFe3O4 particles with different content on the soil urease and catalase activities in pakchoi planting soil were analyzed by pot culture. The results showed that after nanoFe3O4 was added the soil urease and catalase activities were significantly inhibited. In the groups treated with 1%, 2% and 3% nanoFe3O4, the soil urease activity was significantly decreased by 13.9%25.2%33.6% , and the soil catalase activity was significantly decreased by 9.59%10.26%33.04% compared with the control group. It followed that nanoFe3O4 played an inhibiting role in the soil urease and catalase activities, and the higher content of nanoFe3O4 was, the inhibition was stronger. Keywords: nanoFe3O4 particles; Urease activity; Catalase activity
