我国新型肥料产业发展战略研究

Development strategies of the new-type fertilizer industry in China

  • 摘要: 肥料产业服务于农业生产,尿素、磷铵、氯化钾和复合肥等传统化肥产品的大量投入对保障粮食安全发挥了至关重要的作用。随着我国农业发展方式从资源消耗型向绿色可持续型转变,发展新型高效肥料产业,提升肥料产品对粮食安全与生态环境安全的协同保障作用,是现阶段国家农业绿色发展的一个关键举措。新型肥料类型主要有缓/控释肥料、增值肥料、水溶肥料、商品有机肥、微生物肥料等,相比于常规施肥,施用新型肥料普遍能够提高作物产量和养分利用效率,增产率范围为4.6%~17.5%,氮肥利用率提高16.8%~52.3%,农田土壤氨挥发损失量可降低7.2%~50.7%,N2O排放降低8.1%~40.8%,氮淋溶损失降低16.5%~43.8%,氮径流损失降低22.1%~45.4%。经过几十年的跟踪和创新,我国新型肥料形成了产业化,新型肥料总产量已位居世界前列。但由于新型肥料产业起步晚,几乎所有类型的新型肥料生产均存在原创核心技术缺乏,产品特性与农业需求匹配性不高,施肥技术和装备发展滞后,以及监管体系薄弱等问题。为推动新阶段新型肥料产业结构绿色高效转型升级,未来我国的新型肥料产业发展战略核心包括以下4个方面:1) 以农业需求为导向,提升肥料产品与生产需求的匹配度;2) 肥料增效技术由注重养分供给向土壤环境、作物吸收和有效供给综合调控发展,肥料增效材料向高效、环保和价廉方向发展,肥料产品向营养、土壤改良和抗逆等多功能发展;3) 注重最大限度地利用资源,降低能耗,通过大型肥料生产设备的优化和改造,力争实现新型肥料由二次加工到一次生产的突破,实现新型肥料生产的绿色低碳转型;4) 建立健全肥料生产、销售和使用全链条监管体系,保障新型肥料产业的高质量健康发展。

     

    Abstract: The fertilizer industry is the backbone of agriculture. Traditional fertilizers like urea, ammonium phosphate, potassium chloride, and compound fertilizers are heavily invested and play a key role in making sure China has enough food. As China’s agricultural development shifts away from resource consumption and toward green and sustainable development, new-type and high-efficiency fertilizers capable of achieving food security and environmental security become a major demand for green agricultural development. New-type fertilizers in China include slow/controlled-release fertilizer, value-added fertilizer, water-soluble fertilizer, commercial organic fertilizer, and bio-fertilizer. Compared to traditional fertilization, applying new-type fertilizers increases crop yields and nitrogen (N) use efficiency by 4.6%−17.5% and 16.8%−52.3%, and reduces ammonia volatilization, N2O emission, N leaching, and N runoff by 7.2%−50.7%, 8.1%−40.8%, 16.5%−43.8%, and 22.1%−45.4%, respectively. After decades of research and development, China’s new-type fertilizer achieves industrialization and global leadership in production. However, this innovation was met with some limitations, including the short development period of the new-type fertilizer industry, the lack of original core technologies, the low match between fertilizer product characteristics and agricultural requirements, the lagging development of fertilizer application technology and equipment, and the need to improve administrative systems, policies, and laws. The following strategies should be focused on to achieve the transformation and upgrading of the new-type fertilizer industry towards the overall goal of green and high efficiency in the new stage: 1) bridging the gap between fertilizer properties and agricultural practices; 2) increasing fertilizer efficiency by shifting focus from nutrient supply to soil environment and crop absorption. This can be achieved by developing environmentally friendly and cost-effective additives containing plant growth stimulants and soil remediation materials; 3) maximizing resource use and reducing energy consumption during fertilizer processing and preventing new-type fertilizer production from secondary processing; 4) constructing a whole-chain supervision system covering production, marketing, and application of new-type fertilizer to ensure green production, quality retracing, and efficient use.
