We carried out a series of studies on the soil urease activity of the salinized meadow with degenerative Aneurolepidium Chinense in Daan Niuxintaobao during July to October in 2006.

Soil urease activity of the 0 - 10 cm layer had a power-function correlation to rainfall (monthly mean value) and an exponential correlation to soil temperature, which showed that urease activity was deeply influenced by water and heat factors.

Soil urease activity was initially regarded as the function of two factors: buffer and time under the addition of external copper source.

Study on N_2O emission and urease activity in dryland soil;

This paper mainly study on soil urease activity effected by dimehypo, the results showed that dimehypo has remarkable inhibitory on soil urease activity in different ecological zones, soil urease activity reduced with dimehypo concentration increasing, their relationship can be expressed by equation U=1/(β1×C+β0), The ecological dose ED50 is 4.
