摘要
农药精确变量喷施技术是智能化植保机械的重要研究内容,一直是精细农业领域的研究热点,它牵涉到农药有效利用率、农产品安全、环境污染和操作者的人身安全等众多问题。如何按照农艺要求快速准确地进行喷施作业,并使其具有良好的雾化特性和均匀性是变量喷施技术的关键。农药变量喷施过程主要包括喷施决策的生成和喷施决策的执行两个阶段。为此,分类阐述了其国内外研究现状和实现方法,并对其现存问题和发展趋势进行了讨论。
Pesticide variable-rate spray technique,which has been proved to be a research focus in precision agriculture,is an important topic in the field of intelligent crop protection machinery.It influences pesticide efficiency,agricultural product safety,environment pollution,operator＇s safety and many other issues.In accordance with agronomic requirement,fast and accurate spray operation with good atomization characteristics and uniformity is the key of variablerate spray technique.The spray process of the technique mainly contains decision-making phase and implementation phase.This article elaborated the current domestic and abroad research status and implementation methods of the two phases respectively,and also discussed the existing problems and development trend in this field.
