我国变量施肥技术研究现状与发展对策

摘要

Variable rate fertilization is an important content of precision agriculture, is the high yield, high efficiency ag-riculture and the important guarantee of food security. It can effectively control the implementation of the fertilizer on the environment pollution and destruction, greatly improve the fertilizer utilization ratio and reduce the production cost. In this paper, starting from the concept of variable rate fertilization technology. Introducing the current situation of foreign of variable rate fertilization. Analyzing prescription generation technology . fertilizer control technology and fertilizer moni-toring technology in detail. Summarizing the main problems existing at present,basing on the problems put forward deve-lopment countermeasure for variable fertilization technology in China.%变量施肥是精准农业中的一个重要内容，是实现农业高产、高效与粮食安全的重要保证，它的实施可以有效控制化肥对环境的污染和破坏，大大提高肥料的利用率，降低生产成本。为此，从变量施肥技术的概念出发，由变量施肥技术的国外现状引入，具体分析了施肥处方生成技术、肥料施入控制技术及肥料施入监测技术的研究现状，并总结了目前我国变量施肥技术存在的主要问题，针对问题提出了发展对策。
