    摘要:

    冬油菜是我国重要的油料作物和南方主要的冬季轮作作物,发展油菜生产对保障我国粮油安全供给具有重要的战略意义。进入21世纪以来,由于油菜移栽种植转变为直播轻简种植,过去的施肥技术不再适合新的生产模式,油菜产业发展对施肥理论和技术提出了新要求。本文总结了近20年来我国油菜施肥技术领域的研究进展。经过协同攻关,我国农业科技工作者提出了冬油菜“氮磷钾硼镁全营养配合与前促后稳”的养分精准调控策略,建立了冬油菜前期“精准施肥壮苗保群体促丰产”和后期“依靠土壤养分稳供促高效保稳产”的养分调控方法,创新了“精准种类、精准配伍、精准用量、精准时期、精准位置”为核心的“五精准”油菜高效施肥技术,创制了油菜专用全营养配方肥、专用缓释肥和专用控释尿素等系列新肥料产品,优化建立了轻简高效施肥模式并实现规模化应用,支撑了油菜产业的绿色高质高效发展。最后针对我国冬油菜生产面临的新机遇和新挑战,从施肥技术角度提出了展望:加强南方短生育期油菜高效施肥技术、油菜多功能利用的配套施肥技术、应对气候多变的抗灾养分管理技术等研究,进一步加强与现代农业发展相匹配的新型高效专用肥料产品研发与施肥技术创新,重视养分高效油菜品种的选育与应用。

    Abstract:

    Winter rapeseed (Brassica napus L.) is an important oil crop in China and a major winter rotation crop in southern China. Developing rapeseed production is of great strategic significance for ensuring the safe supply of food and oil in China. Since the beginning of the 21st century, the previous fertilization technology is no longer suitable for new production models due to the shift from transplanting rapeseed to direct seeding and light planting. The development of the rapeseed industry has put forward new requirements for the theory and technology of fertilization. This article summarized the progress in the field of rapeseed fertilization technology in China in the past 20 years. The workers from agricultural science and technology in China proposed a precise nutrient regulation strategy for winter rapeseed through collaborative efforts, which involves the combination of nitrogen, phosphorus, potassium, boron, and magnesium, particularly in the promotion of nutrients at the early stage of growth and stabilization of nutrients at the later stages of growth. A nutrient regulation method including “precise fertilization to strengthen seedlings and promote high yield” at the early stage and “relying on stable soil nutrient supply to promote efficient and stable yield” at the later stage for winter rapeseed was established. The “five precision” rapeseed efficient fertilization technology with “precise source, precise ratio, precise rate, precise time, and precise place” as the core was innovated. A series of new fertilizer products including balanced fertilizers with a specialized formula of required nutrients, slow-release fertilizers, and controlled-release urea were developed. A light, simple, and efficient fertilization model was established, optimized and applied at large-scale, supporting the green, high-quality, and efficient development of the rapeseed industry. In response to the new opportunities and challenges faced by winter rapeseed production in China, prospects including strengthening efficient fertilization techniques for short-growth-period rapeseed in southern China, developing fertilization techniques suitable for the multifunctional utilization of rapeseed, exploring nutrient management techniques to cope with climate change, further strengthening the research and development of new high-efficiency specialized fertilizer products and innovation in fertilization technology matching with the development of modern agriculture, and attaching importance to the breeding and application of rapeseed varieties with high nutrient efficiency are proposed from the perspective of fertilization technology.
