摘要
果园植保是果园管理关键环节,其机械化发展水平直接影响水果种植的经济效益。为明确中国果园植保机械化技术与装备未来发展方向,该研究首先介绍了中国果园的主要种植方式、植保机械化发展水平及发展制约的因素,然后重点阐述了管道喷雾、风力辅助喷雾、静电喷雾、循环喷雾、变量喷雾和航空施药等植保机械化关键技术与装备的研究进展,概括分析了上述植保装备的农药利用率情况,最后结合中国果园种植特点提出了推广标准化果园种植方式、发展立体植保施药技术、推广专业化机械植保服务模式和研发智能植保机器人4个方面的建议,以期为中国果园植保机械化发展提供参考。
Orchard spray is a key link to orchard production,due to it occupied nearly 25%of the total workload of orchard management.Moreover,the degree of plant protection mechanization directly affects the economic benefits of fruits.In this review,the orchard characteristic,the general situation of plant protection mechanization and the reasons restricting its development were introduced briefly,in order to clarify the future progress of mechanization technology and equipment for the orchard plant protection in China.The main reason impeding the development of plant protection mechanization can be a large proportion of hilly orchards,including gradient,slope and flat orchard,together with a very complex planting environment.Since the standardized modern orchards are being promoted,the scale is still small,due partly to the extensive management in traditional orchards the high price.Currently,the plant protection mechanization level of flat orchard was 15%,whereas,the hilly orchard was only 7.5%.Therefore,the progress of key plant protection mechanization technologies and equipment was presented in detail,further to improve the mechanization level of plant protection.For example,the pipeline spraying technology and equipment brought good benefits and spraying effects to the hilly orchard,while,the application of air-assisted spraying technology and equipment improved the mechanized operation level of the flat orchard.Electrostatic spraying technology and equipment were especially used to enhance the droplet coverage rate on the back of leaves.While the tunnel spraying technology and equipment increased the droplet density on the canopies,to recovery the droplet that left the target,indicating that it can effectively improve the pesticide utilization.Variable rate spraying technology and equipment were becoming a hot research topic,particularly on the precise control of spray on demand.The core technology of variable rate spraying was target detection,such as ultrasonic detection,laser detection,infrared detection,machine
