摘要:
通过田间大田试验,研究不同梯度生物质炭施入量[0 t/hm2(CK)、10 t/hm2(B1)、20 t/hm2(B2)、30 t/hm2(B3)]对旱作农田土壤温室气体排放的影响。结果表明,施用生物质炭对土壤温室气体排放、增温潜势(GWP)和减排的效应强度(GHGI)具有不同程度的影响,与对照CK处理相比,在生物质炭B1、B2、B3处理条件下,土壤N2O的排放总量在2015年和2016年分别降低了24.55%~45.81%和6.97%~28.80%,处理间差异显著;CO2-C排放量连续2年间分别提高了6.11%~22.84%和11.66%~26.02%,且在B3条件下差异显著;2015年和2016年GWP(100)与对照CK处理相比,分别降低了19.52%~46.53%和8.54%~41.42%;GHGI(CO2+N2O)连续2年显著降低,分别降低了 19.79%~48.28%和9.44%~42.88%。综合连续2年试验结果,生物质炭施用对土壤CO2的排放具有增加趋势,而对降低土壤N2O排放、GWP、GHGI具有持续效应,且高用量(30 t/hm2)下生物质炭的持续效应连续2年间具有稳定性。
