摘要:

耕地是人类赖以生存的物质基础,对保障粮食安全、国民经济发展和社会稳定起着重要的作用。随着中国经济快速发展,城市建设活动占用的土地面积逐渐增加,从而造成耕地面积减少,土地资源紧缺与用地需求增长的矛盾日益加剧。依靠新垦造耕地实现“耕地占补平衡”是保证耕地数量的主要途径。本文介绍了目前新垦耕地的主要障碍因子和培肥现状的基本概况,重点综述了土壤肥力综合评价技术与方法和新垦耕地土壤有机质快速提升技术现状与问题,并从新垦耕地土壤的肥力状况、障碍因子及评价体系研究,综合提升新垦土壤生产与生态功能的高效绿色培肥新产品的研发和加强新垦土壤关键障碍因子消减与肥力协同提升关键技术研究3个方面提出了具体的对策和建议。

Abstract:

Cultivated land is the material basis for human survival, which plays an important role in ensuring food security, national economic development and social stability. With the rapid development of Chinese economy, the land area occupied by urban construction activities has gradually increased, resulting in the decrease of cultivated land area, and the contradiction between the shortage of land resources and the growth of land demand is increasing. Newly reclaimed land is the main way to guarantee the quantity of cultivated land, which helps to realize the balance between occupation and compensation of cultivated land. This paper introduced the main obstacle factors of newly cultivated land and the basic situation of fertility improvement. The comprehensive evaluation technology and method of soil fertility, and the present situation and problems of rapid improvement technology of soil organic matter in newly reclaimed land were emphatically summarized. In addition, specific countermeasures and suggestions were put forward from three aspects: (1) researches on fertility status, obstacle factors and evaluation system of newly reclaimed land soil; (2) research and development of new green fertilizer products that comprehensively improve the production and ecological function of newly reclaimed soil; (3) researches on the key technologies that collaboratively reduce the key obstacle factors and improve the fertility of newly reclaimed soil.

Key words: newly reclaimed, soil fertility, obstacle factor, strategy
