[Effects of nitrogen deposition and biochar application on soil NO fluxes in a Moso bamboo plantation].

In July 2019-July 2020, we conducted a field trial to examine the effects of nitrogen addition (60 kg N·hm·a), biochar application (10 t·hm), and their combination on soil NO emission and the relationship between soil NO emission and environmental factors in a typical Moso bamboo () plantation in Hangzhou City of Zhejiang Province. Soil NO 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 NO emission by 14.
