现代农业大量使用农药、化肥、农膜、生长调节剂等农用化学品,导致农业生态系统功能退化。国家多项文件指出要加大生态系统保护力度,促进农业可持续发展。农业生态系统保育就是要采取措施使农业生态系统功能可持续地充分发挥出来。生物多样性对加强农业生态系统的稳定性和促进系统功能的发挥具有至关重要的作用。农业生态系统是受人类调控的生态系统,采取生态化的农业管理措施对农业生态系统保育是必不可少的人工干预措施。有机农业的核心是建立和恢复农业生态系统的生物多样性和良性循环,河南鑫贞德有机农业有限公司经过多年有机农业生产,农业生态系统保育效果良好,较好地实践了农业生态系统有关理论,编者对此进行了分析总结,以供参考。
Agricultural chemicals such as pesticides, chemical fertilizers, agricultural films and growth regulators are widely used in modern agriculture, which lead to the degradation of agricultural ecosystem functions. A number of state documents point out that efforts should be made to strengthen ecosystem protection and promote sustainable development of agriculture. The conservation of agricultural ecosystem is to take measures to make the function of agricultural ecosystem sustainable and give full play. Biodiversity plays a crucial role in enhancing the stability of agro-ecosystem and promoting the functioning of the system. Agro-ecosystem is an ecosystem regulated by human being. It is necessary to take ecological agricultural management measures for agro-ecosystem conservation. The core of organic agriculture is to establish and restore the biological diversity and virtuous circle of the agricultural ecosystem. After years of organic agricultural production, the effect of agricultural ecosystem conservation is good, the relevant theory of agro-ecosystem has been well put into practice, and the editor has made an analysis and summary for reference.
