- Abstract
In July 2019-July 2020, we conducted a field trial to examine the effects of nitrogen addition (60 kg N·hm
-2 ·a-1 ), biochar application (10 t·hm-2 ), and their combination on soil N2 O emission and the relationship between soil N2 O emission and environmental factors in a typical Moso bamboo ( Phyllostachys edulis ) plantation in Hangzhou City of Zhejiang Province. Soil N2 O flux of Moso bamboo plantation was measured by the static chamber-gas chromatography technique. The results showed that nitrogen addition treatment increased the annual cumulative N2 O emission by 14.6%, while biochar application and the combination treatment reduced it by 20.8% and 10.6%, respectively. Soil N2 O flux rate was significantly correlated with soil temperature, NO3 -N concentration, urease and protease activities, and soil NH- -N concentration across all treatments. In conclusion, under the background of nitrogen deposition, the application of biochar would have a significant reduction effect on soil N4 + -N concentration across all treatments. In conclusion, under the background of nitrogen deposition, the application of biochar would have a significant reduction effect on soil N2 O fluxes in Moso bamboo plantations.- Published
