摘要
传统的施肥方式存在着结构不合理、肥料利用率低、环境污染等问题。为了解决这些问题,必须进行因土、因时、因作物全面平衡施肥,即变量施肥。变量施肥技术是精准农业的重要内容之一。为此,综述了变量施肥的基本概念、研究现状以及技术体系,并对变量施肥技术体系的发展趋势进行了分析与展望。
There existed unreasonable structure,low utilization rate of fertilizer,environmental pollution and other problems in traditional fertilization mode.In order to solve these problems,comprehensive balanced fertilization,namely variable rate fertilization,must be carried out according to field,climate and crops,variable rate fertilization technology is one of important contents of precision agriculture.This paper reviewed basic concept,research status and technology system of variable rate fertilization,analysed and prospected development trend of technology system of variable rate fertilization.
