生物质炭施用对土壤中硝态氮的水平运移速率和水平运移浓度影响显著。随着生物质炭施用量的增加,硝态氮的水平运移速率和水平运移浓度呈先增加后降低的趋势,而土壤水扩散率呈逐渐降低趋势。C

]
生物质炭可以改善土壤的理化性状,促进硝态氮的水平运移,在利用生物质炭改良旱地红壤理化性状的同时,也要注意防止氮素流失对环境的影响,降低其对地表水的潜在污染风险。
[Objective] This experiment studied the effects of biochar addition on the content and horizontal transport of NO3--N in upland red soil in laboratory to provide scientific bases for water management and environmental protection in the fields.[Methods] Moisture diffusion rate meter was used to determine the horizontal transport velocity and concentration of NO3--N in soil at biochar addition rates of 0

30 and 40 t/hm2.[Results] The horizontal transport velocity and concentration of NO3--N were significantly affected by biochar addition. A same trend
which performed an increase at first and then a decrease with the biochar application rate increased
was found in the horizontal transport velocity and concentration of NO3--N in soil and the diffusivity decreased with the increasing rate of biochar addition. When the application rate of biochar was 30 t/hm2
the horizontal transport velocity and concentration of NO3--N in soil got the highest
which were 0.67 cm/min and 165.52 mg/kg
respectively. When the application rate of biochar was 40 t/hm2
the horizontal transport velocity and concentration of NO3--N were lower than those of 30 t/hm2. The transport concentration of NO3--N reached the maximum value at the surface of wet spearhead in all treatments
which existing on the interface between wet and dry soil. Biochar addition decreased the soil bulk density but increased the soil organic carbon content and total porosity so as to the horizontal transport of NO3--N in different treatments were changeable.[Conclusion] Biochar addition can improve the soil properties
and promote the horizontal transport of NO3--N in upland red soil. It is very important to pay attention to prevent the pollution of leaching loss of nitrogen and reduce the potential risk of surface water.
