1、专业文献综述题目:果园多功能机--深施肥装置的设计姓名:学院:专业:班级:学号:指导教师:职称:果园多功能机---深施肥装置的设计作者：指导教师：摘要：针对一机多用既可以用于给果园施肥、覆土松土除草，又可以代替挖穴机，既适用果树等大型植物，又适用于大型农田作物；既可以在小面积的温室里单人作业，也可以与拖拉机或畜力车等配套在大田里集体作业。论述了果园功能机的国内研究现状，介绍了几种典型田园管理机的结构原理和研究成果。将深施肥装置分为液体注入式和挖掘施肥式两类，同时也指出了着两类所存所在的一些问题：前者工

2、作效率高、施肥量较小、结构复杂且对肥料的要求高；后者易损伤果树根系且影响土地的整洁性，需要施肥结束后进行简单的整地作业。挖掘装置分为三种形式，即螺旋式、铣刀旋转开沟式和履带旋转开沟式。履带旋转开沟式施肥装置是一种比较好的挖掘施肥模式，在现有螺旋式的基础上，简化结构、提高机构的工作可靠性和作业效率，是深施肥装置的研究方向。关键词：一机多用；果园功能机；田园管理机；挖掘装置Orchardmuti_functionmachine---applyfertilizerdeeplythedesignofinsta
