[目的
]
探究冰糖橙种植园土壤团聚体的特征以及影响因素,为减少土壤侵蚀,增加柑橘园土壤保水保肥能力提供科学参考。 [方法
]
采集板页岩风化物、紫色砂岩风化物、砂岩风化物、第四纪红土风化物发育的冰糖橙种植园土壤样本,并同步收集相关的耕作、地理等信息;采用土壤结构稳定性指标R
0.25
,GWD,MWD、分形维数(D)与土壤可蚀性K值对团聚体及其有机碳含量等进行方差分析、相关分析。 [结果
]
①粒径>0.25 mm的团聚体占总团聚体的78%~85%。随着团聚体粒径减小,分级土壤含量整体呈逐渐减小趋势。 ②4种母质发育的土壤GWD在0.536~0.797之间;MWD在0.890~1.208之间;分形维数(D)在2.434~2.480之间;土壤可蚀性K值在0.060 8~0.069 7之间。 ③有机碳含量随着粒径增大有先减小后增大趋势,整体上呈V形分布,其中0.250~0.053 mm微团聚体的有机碳含量最低;大团聚体的有机碳相对贡献率在82%~87%。 ④随着种植年限增加,外源有机碳的不断输入,土壤结构稳定性指标R
0.25
,GWD与MWD极显著增大,分形维数(D)与土壤可蚀性K值极显著减小;说明土壤结构的稳定性在不断增强。 [结论
]
研究区冰糖橙种植园大团聚体含量高,土壤稳定性较强;且各母质的土壤稳定性处于同一水平。成土母质的砂粒含量与人为扰动直接对团聚体稳定性产生作用、外源有机碳、种植年限,纬度与海拔共同作用于有机胶结物质来影响土壤稳定性。
[Objective] The soil aggregates of Bingsugar orange orchards and the factors affecting them were characterized in order to reduce soil erosion and increase the water and fertility retention capacity of citrus orchards. [Methods] Soil samples were collected from weathered slate
weathered purple sandstone
sandstone
and weathered Quaternary laterite developed in a Bingsugar orange orchard. Related tillage and geographic information were collected simultaneously. ANOVA and correlation analysis were performed on the agglomerated data and their organic carbon contents using soil structural stability indexes R0.25
GWD
MWD
fractal dimension (D)
and soil erodibility K value. [Results] ① Agglomerates with particle sizes >0.25 mm accounted for 78%~85% of the total agglomerates. Graded soil content gradually decreased with decreasing agglomerate particle size. ② The GWD of the soils developed by the four matrices ranged from 0.536~0.797; MWD ranged from 0.890~1.208; fractal dimension (D) ranged from 2.434~2.480; and soil erodibility K value ranged from 0.060 8~0.0 697. ③ Organic carbon content decreased with increasing particle size and then increased
with an overall V-shaped distribution. Organic carbon content of the 0.250~0.053 mm microaggregates was the lowest. The relative contribution of organic carbon of large agglomerates was 82%~87%. ④ Soil structure stability indexes R0.25
GWD
and MWD significantly increased with increasing number of planting years and the continuous input of exogenous organic carbon. Fractal dimension (D) and soil erodibility K values significantly decreased at the same time
indicating increasing soil structure stability. [Conclusion] Soil stability was high with high content of large agglomerates in a Bingsugar orange orchard in Hu’nan Province. The soil stability of each parent material was at the same level. Sand content of the soil-forming parent material and anthropogenic disturbance directly affected the role of agglomerate stability
exogenous organic carbon
and planting years. Latitude and altitude jointly influence soil stability by organic colloidal material. The sand content of the parent material and anthropogenic disturbance directly contribute to the stability of the aggregates. Exogenous organic carbon
age of cultivation
latitude and altitude combine to influence soil stability through the organic cementing material.
