[目的
]
研究黑土区低山丘陵地形侵蚀沟土壤养分特征及其影响因素,为黑土区土地资源合理运用,土壤肥力精确化管理和退化土壤修复工作提供数据与理论支持。[方法
]
以黑龙江省延寿县不同发育类型侵蚀沟表层土壤作为研究对象,对0—40 cm层侵蚀沟各部位的土壤进行取样测定,量化分析土壤养分特征。[结果
]
①不同侵蚀沟道间有机质、全氮、全磷、全钾、速效磷、速效钾、碱解氮含量较CK差异显著(p<0.05),随侵蚀沟发育,0—40 cm层的土壤有机质含量呈递减趋势,土壤全氮、全磷、全钾、速效磷、速效钾、碱解氮含量总体呈下降趋势。随着土层加深,土壤养分差异显著(p<0.05),呈下降趋势。受侵蚀—沉积影响,土壤有机质、全氮、全钾、碱解氮含量在沟头段降幅明显;土壤有机质、有效磷、有效钾含量在沟尾因沉积作用下降平缓。②土壤退化指数在0—40 cm层呈A

,随侵蚀沟发育,土壤退化程度加重。[结论
]
土壤养分与容重总体呈显著负相关,与土壤水稳性团聚体含量、黏粒含量呈显著正相关;土壤剖面与构型差异是造成土壤养分差异的根本原因,侵蚀沟发育是土壤养分变化的次要原因,土壤有机质、全氮、全钾含量也受到部位差异影响。
[Objective] The soil nutrient characteristics and influencing factors of surface soil gully erosion for low hilly terrain in the black soil area were studied in order to provide data and theoretical support for the rational use of land resources
accurate management of soil fertility
and restoration of degraded soil in the black soil area. [Methods] Surface soil gully erosion for different types of eroded ditches in Yanshou County
Heilongjiang Province was determined by measuring and analyzing soil samples from the 0—40 cm layer in each part of the erosion gully. [Results] ① The contents of soil organic matter
total nitrogen
total phosphorus
total potassium
available phosphorus
available potassium
and alkali hydrolyzable nitrogen were significantly different (p<0.05) for different erosion gully types compared with the check treatment. As an erosion gully developed
soil organic matter decreased in the 0—40 cm layer
and the contents of total nitrogen
total phosphorus
total potassium
available phosphorus
available potassium
and alkali hydrolyzable nitrogen also decreased. These nutrient contents were significantly different (p<0.05) in different soil layers. Soil nutrient contents decreased with increasing depth. Because of erosion deposition
the contents of soil organic matter
total nitrogen
total potassium
and alkali hydrolyzable nitrogen decreased dramatically at the head of the gully
and at the same time
the contents of soil organic matter
available phosphorus
and available potassium decreased slowly. ② The soil degradation index followed the order of CK>A2>A1>A3 in the 0—40 cm layer as erosion gullies developed
and the soil was gradually degraded. [Conclusion] Soil nutrients had an overall significant negative correlation with bulk density
and soil nutrients were positively correlated with water stable aggregates and clay content. Soil profile differences were the fundamental reason for the variation in soil nutrients. Erosion gully development was the secondary reason for nutrient changes. The contents of soil organic matter
total nitrogen
and total potassium were also affected by positional differences.
