摘要
化肥对农业生产发展起着至关重要的作用,关系着农作物的产量及质量。近年来,我国化肥持续减量,实现负增长,而不合理施肥现象依然存在,导致土地质量下降、农业面源污染等问题。为推动我国农业可持续发展,响应国家农业绿色发展政策,减肥增效技术的应用及推广势在必行。本文以文献资料及统计数据为基础,分析了我国农业化肥施用现状,总结归纳了科学施肥技术及效应,探讨减肥增效技术推广对策,为推动农业绿色发展提供参考。
Chemical fertilizer plays a vital role in the development of agricultural production and is related to the yield and quality of crops. In recent years, the amount of chemical fertilizer in China has been continuously reduced and negative growth has been achieved. However, unreasonable fertilization still exists, leading to the decline of land quality, agricultural non-point source pollution and other problems. In order to promote the sustainable development of China’s agriculture and respond to the national agricultural green development policy, the application and promotion of reducing fertilizer application and increasing efficiency technology is imperative. Based on the literature and statistical data, this paper analyzes the current situation of agricultural fertilizer application in China, summarizes the scientific fertilization technology and effects, and discusses the promotion countermeasures of weight loss and efficiency increasing technology, which provides reference for promoting the green development of agriculture.
