Composition for promoting formation of soil aggregates and application method

The invention relates to a composition for promoting formation of soil aggregates and an application method, which belong to the technical field of soil improvement by applying a water and fertilizer integration technology. The composition for promoting the formation of the soil aggregates mainly comprises the following raw materials in parts by weight: 20-40 parts of a water-soluble carbon mixture, 30-35 parts of a sugar alcohol mixture and 25-35 parts of liquid vegetable oil. The composition can promote the formation of soil aggregates, improve the stability of the soil aggregates, maintain the fertility of the soil, restrain the degradation of high-quality farmland and realize the sustainable development of agriculture. And existing equipment (water and fertilizer integrated equipment with huge national investment) can be utilized for large-area popularization and application, re-construction is avoided, and the method is suitable for wide popularization and application. 本发明涉及一种促进土壤团聚体形成的组合物及施用方法，属于运用水肥一体化
