果园精准喷雾机研究现状与发展趋势OA

Orchard plant protection and pesticide application is the key link to ensure the health of fruit trees and the safety of agricultural products.Its mechanization and precision level directly affect the orchard production efficiency and ecological environment.The orchards in China are mainly managed by small-scale farmers.The existing pesticide application equipment generally has problems such as low operating efficiency,uneven distribution of droplet deposition,serious pesticide loss and high risk of environmental pollution.The research and development of precision sprayers started relatively late.At present,the mainstream equipment often adopts large-capacity leaching or fixed-dose continuous spraying,which is prone to producing dense droplets,resulting in low utilization rate of pesticides and increased waste of resources.Thus,this article takes precision and intelligent orchard sprayers as the research object,systematically reviews its research status and technology evolution in China and abroad,focuses on the analysis of system composition and key technological progress,summarizes the application effect in different orchard scenarios,and foresees its future development trend,thereby pro-viding a reference for the intelligent upgrading of orchard plant protection equipment and pesticide reduction and efficiency improvement.
