施肥技术的进步是保障玉米大面积高产稳产的重要措施之一。本文比较了美国雨养玉米和中国东北春玉米机械化施肥技术现状。美国在玉米推荐施肥技术方面的研究已经十分完善,并且施肥机械高度发达以适应大农场田块作业。我国在施肥技术方面的也进行了多方面的深入研究,然而施肥机械的发展还处在较低的水平。为适应我国土地规模化经营的发展,我们应该借鉴美国等发达国家的经验,将施肥技术与施肥机械相结合,发展机械化的施肥技术。文章最后展望了我国玉米机械化施肥技术的发展趋势。
英文摘要:
Advanced machinery-based fertilization technology is one of the important measurements to guarantee high maize yield in a large scale land. This paper introduced the current status of machinery-based fertilization technology in the rain-fed maize in the United States and the spring maize in the northeast of China. Fertilization recommendation technology has been studied thoroughly in United States, and the fertilizer machinery was highly developed to match the requirement of farmers with the large scale land. In China, researches on fertilizer recommendation have been carried out across the county. However, less attention has been paid on the development of fertilizer machinery. With the fast development of land merge in the countryside in China, we should learn from the experience of the United States on the machinery-based fertilization techniques and match the fertilization techniques with the machinery. The possible trend in the mechanized fertilizer application techniques in maize was discussed.
