| 摘 要： | 土壤是温室气体的重要排放源,在土壤中施入生物质炭和有机物料对土壤微生物在土壤碳氮转化和微量气体代谢方面有着重要作用,不过迄今在生物质炭和有机物料混施对土壤温室气体排放和微生物活性的影响方面的研究尚少.本研究采用室内培养试验,利用土壤添加生物质炭和生物质炭与不同有机物料混施,探究生物质炭和有机物料混施对土壤温室气体排放及微生物活性的影响.共设5个处理:新鲜土壤(S)、新鲜土壤+2%生物质炭(SB)、新鲜土壤+2%生物质炭+1%大豆饼(SBS)、新鲜土壤+2%生物质炭+1%小麦秸秆(SBW)、新鲜土壤+2%生物质炭+1%鸡粪(SBC).研究表明:只添加生物质炭对温室气体的排放影响不明显;生物质炭与有机物料混施使土壤的CO2、N2O排放明显增加,而对CH4的排放影响不明显;从温室气体增温潜势(GWP)变化可以看出有机物料施用对温室效应具有明显的增强作用;生物质炭与有机物料混施在一定程度上增加微生物生物量碳和代谢熵(q CO2),各处理的代谢熵是对照处理S的0.18~4.37倍;不同有机物料对FDA水解酶、过氧化氢酶、脲酶和碱性磷酸酶活性都表现为激活作用.

| Abstract: | The application of biochar and organic fertilizer to soil, an important source of greenhouse gases, plays an important role in soil carbon nitrogen conversion and micro-gas metabolism, however few studies have focused on the soil microbial activity and soil greenhouse gas emissions influenced by the mixed application of biochar and organic fertilizers. This study adopts indoor culture experiment, using soil added biochar and biochar mixed with different organic fertilizers, to explore the effects of biochar and different organic fertilizers on soil greenhouse gas emission and soil microbial activity. Five treatments were set up in this experiment, that is, fresh soil (S), fresh soil + 2% biochar (SB), fresh soil + 2% biochar + 1% soybean cake (SBS), fresh soil + 2% biochar + 1% wheat straw (SBW), fresh soil + 2% biochar + 1% chicken manure (SBC). The results show that the effect of adding biochar alone to soil on greenhouse gas emission is not obvious; The application of mixed biochar and organic fertilizer can significantly increase the soil CO2 and N2O emissions, while the effect on CH4 emission is not obvious; application of organic fertilizer presents a sizable contribution to the greenhouse effect according to the dynamics of global warming potential (GWP); the mixed application of biochar and organic fertilizer also can increase microbial biomass carbon and metabolic entropy (qCO2) to a certain degree, and microbial biomass carbon exhibits an increase-decrease trend, with the metabolic entropy of each treatment is 0.18~4.37 times higher than that of S; Different organic fertilizers all enhance soil FDA hydrolysis activity, catalase activity, urease activity and alkaline phosphatase activity. |
