基于变量依据与实现方式的变量施药技术研究现状与展望
Research status and prospects of variable-rate chemical application technology based on decision criteria and implementation methods
摘要
Abstract
As a core component of precision agriculture,variable-rate chemical application technology is recognized as a critical approach to addressing issues such as low pesticide utilization and severe environmental pollution resulting from traditional constant-rate application methods.A systematic review was conducted within the technical framework of"decision basis-implementation methods".First,the fundamental principles and typical characteristics of the two mainstream decision-making technical pathways-namely,map-based and sensor-based approaches-were elaborated.Subsequently,an in-depth analysis was provided regarding the working mechanisms,research status,and development trends of key implementation methods,including pressure regulation,flow control,and on-line mixture of pesticide liquid.Based on this analysis,the advantages and limitations of existing variable-rate application technology systems were summarized.Furthermore,future research directions were proposed,emphasizing the development of intelligent decision-making models,innovation in precision actuating mechanisms,and system integration and application,with the aim of supporting further advancements in both research and practical implementation of this technology.关键词
