摘要

摘要: 在10℃、20℃、30℃温度条件下,采用室内模拟试验,研究不同施肥处理对龙眼园土壤呼吸、土壤可溶性有机碳(DOC)以及土壤微生物量碳(MBC)含量的影响。结果表明:在85 d的培养期内各施肥处理土壤呼吸速率都表现为培养前期保持较高水平,之后快速下降,培养后期保持相对稳定的趋势,土壤CO2累积排放量为1439～4443 mg.kg-1,单施菌渣有机肥土壤CO2累积排放量最大;增温明显促进了土壤呼吸,土壤温度系数Q10值在1.49～2.08,CK处理的Q10值最小,单施有机肥处理Q10值最大;3种温度处理下,施肥均显著提高了土壤DOC和土壤MBC含量,单施菌渣有机肥提高幅度最大,其他施肥处理间差异不显著。

Abstract: In laboratory,the soil respiration,dissolved organic carbon(DOC) and microbial biomass carbon(MBC) at 10℃,20℃ and 30℃ with different fertilizations in soil from a longan orchard were studied.The results showed that,in 85 days of incubation,(a)the CO2 production rate was high in the early stage followed by a rapid decrease and stabilization afterwards.The total cumulative amounts of CO2 ranged from 1439 to 4443 mg·kg-1;(b)temperature significantly contributed to the soil respiration-the soil temperature coefficient,Q10 was between 1.49 and 2.08,with the CK the lowest and the N5 treated the greatest;and(c)fungal waste application significantly increased soil respiration,as well as the soil DOC and MBC contents,while other fertilization treatments showed no significant difference.
