硝化抑制剂双氰胺施用对水稻产量和温室气体排放的影响
Effects of Nitrification Inhibitor Dicyandiamide Application on Rice Yield and Greenhouse Gas Emissions
摘要
Abstract
A pot experiment was conducted to investigate the effects of applying nitrification inhibitor dicyandiamide on rice yield and greenhouse gas emissions with the conventional japonica rice variety Nanjing 9108 as the test material.Two treatments:conventional nitrogen fertilizer(CK)and conventional nitrogen fertilizer combined with dicyandiamide(DCD)were set up.The results showed that compared to CK,DCD treatment significantly increased rice yield(15.1％)and aboveground biomass(28.4％),but reduced methane(CH4)emissions(22.2％),nitrous oxide(N2O)emissions(56.0％),area-scaled global warming potential(GWP)(24.4％),and yield-scaled GWP(GHGI)(31.7％).It can be seen that DCD can increase grain yield and mitigate greenhouse gas emissions simultaneously in rice field.关键词
