[Effects of soil moisture and temperature on N2O production rate of meadow grassland soil].
With incubation test, this paper studied the effects of soil moisture and temperature on the N2O production rate of meadow grassland chernozem in Inner Mongolia. The results showed that soil moisture had a significant effect on the N2O production rate, with a non-linear relationship between them. Soil temperature had less effect than soil moisture. Their effects on the test soil N2O production rate at different growth stages could be described as a multi-order polynomial relationship y = ax3 + bx2 + cx + d, where a, b, c and d were the constants.
