摘要
本试验结果表明:施用有机物,不仅提高了土壤有机质的含量和活性,而且改善了土壤有机-无机复合体的性质。有利于土壤有机质的更新和促进土壤腐殖质的活化。还对改善土壤养分供应能力和缓冲能力,土壤的物理性质,土壤团聚体的形成和土壤结构的形成具有深刻的影响。
The experimental results indicated that the application of organic matter played an important role in the increasing of soil fertility, not only increased the soil organic matter content and its activity, but also improved the organic mineral complex properties, which was conducive to the renewal of soil organic matter, and promoted the activation of soil humus, and it had the significant effects on the improvement of soil nutrients supply capacity, cation exchange ability, soil physical properties and the formation of soil aggregates and structure.
