| 摘要: |
| 提升土壤肥力是维持农业可持续发展和保障我国粮食安全的重要保证。为了从根本上实现基础地力相对较差地块的土壤肥力提升目标,本研究通过对土壤肥力提升原理与技术研究进展的系统总结,围绕土壤肥力概念、土壤肥力评价指标与方法、土壤肥力与作物产量的关系、土壤肥力提升的技术措施和研究展望五个方面进行了详细的阐述。分析结果表明,有机肥物料,尤其是加工后的生物炭和商品有机肥的施用,是我国现阶段提升土壤肥力的关键技术措施,而分类建立生物炭和有机肥生产和施用的技术与标准,发展有机无机配施理论,则是今后较长一段时间内实现土壤肥力提升的重要研究方向。 |

| Abstract: |
| Improving soil fertility is an important guarantee to maintain sustainable agricultural development and ensure food security in China. ToSfundamentally realize the increase of soil fertility, this study systematically summarized the development of soil fertility improvement principle and technology. SThe concept of soil fertility, soil fertility evaluation index and method, the relationship between soil fertility and crop yield, and the prospects of soil fertility improvement are thoroughly reviewed in this article. The analysis results show that the application of organic materials, especially processed biochar and commodity organic fertilizer, is the key technical method to improve the soil fertility at the present stage in China. Establishing the technology and standard of biochar and organic fertilizer production and application, and developing the theory of organic and inorganic combined applicationSis an important research direction to improve soil fertility in a long period of time in the future. |
