紫花苜蓿的高产栽培是国内外农学家争相研究的热点问题,而施肥技术是紫花苜蓿高产栽培的关键技术之一。因此,有必要对紫花苜蓿施肥技术的研究进行梳理并概述,以期为紫花苜蓿的产业发展、施肥技术的深化研究提供理论参考。文章着重综述了紫花苜蓿生产栽培中氮肥、磷肥、钾肥的肥料效应,同时阐述了紫花苜蓿施肥技术特点及研究发展方向。
The high-yielding cultivation of alfalfa is a hot issue for agronomists competing at home and abroad, and fertilization technology is one of the key technologies for high-yield cultivation of alfalfa. Therefore, it is necessary to sort out and summarize the research on fertilization technology of alfalfa in order to provide theoretical reference for the further development of alfalfa industry and fertilization technology. This paper focuses on the fertilizer effects of nitrogen fertilizer, phosphate fertilizer and potash fertilizer on the production and cultivation of alfalfa. At the same time, the characteristics and research direction of the technology of alfalfa fertilizer application are described.
