以江西临川县小华山第四纪红色粘土发育的红壤为研究对象。结果表明，有机－无机复合体品质与土壤肥力间呈现较好的相关性。植物活动和人为的耕作管理可以提高土壤复合体的数量和品质，从而提高肥力，加速土壤熟化。因此，加强水土保持，改善土壤生态环境，促进植物和土壤动物的活动，积累高品质的有机残体，改善土壤水分状况是减少土壤胶体损失，培肥土壤的重要途径。 The red soil developed from Quaternary red clay in Xiaohua Mountain, Linchuan County, Jiangxi Province was used as the research object. The results showed that there was a good correlation between the quality of organic-inorganic composites and soil fertility. Plant activity and man-made farming practices can increase the amount and quality of soil complexes, increasing fertility and accelerating soil ripening. Therefore, strengthening soil and water conservation, improving the soil ecological environment, promoting the activities of plants and soil animals, accumulating high-quality organic residues and improving soil moisture status are important ways to reduce soil colloid loss and fertilize the soil.
