土壤是农业生产的重要基础,也是人类赖以生存的保障,其不仅关系食物安全供应,而且直接影响生态环境。土壤肥力是发展现代农业的重要支撑,其有效的培育涉及多学科与多专业,需要系统创新与联合攻关,如今人们对土壤肥力的认识已经从农业生产向环境安全、资源利用、生态健康及全球变化等方向转变与提升。本文从土肥长期定位研究、土壤肥力培育技术、现代农业发展等方面阐述内在关系及其特点,同时分析了现代土壤学研究领域所面临的重要挑战与发展趋势,并提出若干建议与对策。
Soil is an important foundation for agricultural production and also a guarantee for the survival of human beings. It not only affects the supply of food safety, but also directly affects the ecological environment. Soil fertility is an important support for the development of modern agriculture. Its effective cultivation involves multidisciplinary and multi-disciplinary needs of system innovation and joint research. Nowadays, people’s understanding of soil fertility has gone from agricultural production to environmental safety, resource utilization, ecological health and global Changes and other changes and enhance the direction. This article elaborates the internal relations and their characteristics from the aspects of long-term positioning of soil fertility, soil fertility cultivation technology and modern agricultural development. At the same time, it analyzes the important challenges and development trends in the field of modern soil science and puts forward some suggestions and countermeasures.
