Abstract

Dynamic light scattering (DLS) and phase analysis light scattering (PALS) have been used to study the physical and chemical characteristics of organo-clay complexes of soddy-podzolic soils (Albic Retisols (Loamic, Cutanic, Differentic, Ochric)) of forest sites of the Central Forest Reserve. The study of the chronosequence of abandoned agricultural soils afforested for 100 years showed that the value of the average diameter of the organo-clay complexes slightly decreased compared to that at the site with minimum duration of afforestation (5–7 years), but remained still higher than in the forest soils. Multiple linear regression statistical models were developed to predict the average diameter of clay particles. The best model (r = 0.83), where all parameters were significant (P < 0.05), included the content of clay and carbon concentration in clay. The chronosequence of postagrogenic soddy-podzolic soils demonstrated the proximity of the colloidal system stability, but in a peptization state, as evidenced by the values of zeta potential and average diameter of the clay particles.

利用动态光散射和相分析光散射研究白藜芦醇时间序列有机-粘土配合物的理化特性

摘要

动态光散射（DLS）和相分析光散射（PALS）已用于研究森林地点的泥泞土壤-土质土壤（有机质网状土（土生，角质，微分，O））的有机粘土复合物的物理和化学特性。中央森林保护区。对植树造林100年的废弃农业土壤的时间序列研究表明，与最小造林持续时间（5-7年）相比，有机粘土复合物的平均直径值略有下降，但仍保持不变高于森林土壤。建立了多个线性回归统计模型来预测粘土颗粒的平均直径。最佳模型（r = 0.83），其中所有参数均显着（P<0.05），包括粘土的含量和粘土中的碳浓度。农杆菌后土壤的时间序列表明胶体系统稳定性接近，但处于胶溶状态，这由ζ电势值和粘土颗粒的平均直径证明。
