Effects of Carbon Addition and Biochemical Control on N2O Emission from Facility Vegetable Soil
The experiment was carried out with soil of greenhouse in Yongqing, Hebei Province, under constant temperature(25±1)℃ and soil moisture (70% WFPS), using the static incubation method to study the effect of different management controls, i.e. urea, controlled release urea, straw, biochar, dicyandiami...
