中文摘要:为探讨施灌沼肥对土壤氨挥发和氮素下渗的影响,在室温条件下,采用土柱模拟试验,系统研究沼肥不同施用量和不同施用深度对土壤表面的NH3挥发及土壤垂直剖面上的总氮、NH+4N、NO-3N下渗的影响规律。结果表明:表施沼肥时,土壤表面的NH3挥发累积量和挥发的延续时间均随沼肥施用量的增加而增加;土壤垂直剖面上的含水率、总氮和NH+4N均主要集中在表层土壤,而NO-3N可迁移至较深层土壤。底施沼肥时,NH3挥发累积量随着沼肥施用深度的增加而减少,施用深度为10cm时便可有效减少沼肥的NH3挥发损失;同时土壤垂直剖面上的含水率和总氮、NH+4N、NO-3N质量比的最高点均与沼肥施用深度呈显著正相关。

Abstract:In order to investigate the law of ammonia volatilization and nitrogen infiltration in the process of biogas slurry application, the influence rules of different application rate and depth of biogas slurry on the ammonia volatilization of the soil surface and the infiltration of total nitrogen, ammonia nitrogen and nitrate nitrogen in vertical soil profile were explored systematically by soil column experiments at room temperature. The experimental results showed that the total ammonia volatilization of the soil surface and the duration of volatilization were all positively correlated with biogas slurry application rate. The moisture content, total nitrogen and ammonia nitrogen in vertical soil profile were mainly distributed in topsoil. But the nitrate nitrogen had migrated to deep layer soil with the water infiltration of biogas slurry. The total ammonia volatilization of the soil surface decreased with the increase of biogas slurry application depth when the biogas slurry was used as basic fertilizer. The ammonia volatilization rate of biogas slurry could be effectively reduced when the biogas slurry application depth was ten centimeters. And the peaks of total nitrogen, ammonia nitrogen and nitrate nitrogen in vertical soil profile were all positively correlated with biogas slurry application depth.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
