该机器主要用于各类果树的施肥作业。传统果农对果树施肥时，要分别完成挖坑、填肥、埋土3个步骤。而该机器可以将其简化组合为一个步骤—推动果树专用施肥器绕果树转动一周，即可同时完成三项工作，且只需单人操作。该机器主要由机架、旋柄、开沟器、排肥器、覆土装置和调节装置等部分组成。使用时，将其机架上的弧形卡槽卡在果树树干位置，推动旋柄使机器绕果树旋转一周，就可以轻便地完成绕果树开沟、施肥一周，同时完成覆土。通过调节装置，可根据果树的大小、生长状况等不同，适当调节施肥量、施肥深浅、施肥距离等，还可以调节旋柄的高低，以适应不同的操作者。该机械具有省时省力，对果树根系伤害小，施肥均匀等优点。

This device is mainly designed for fertilization works for different kinds of fruit trees.It could simplify the tra-ditional fertilizing methods which are separately digging, fertilizing, and filling to one combined step.The simplified step is riding the device around the tree with three different operations easily done by one person.This advanced device is composed by rack, screwing handle, opener, wheel, filling devices and controlling sets.When operating, people just need to get the arc slot of the device rack stuck upon the root of the tree, then push screwing handle in order to ride the device around the tree.In this way,the digging, fertilizing combined with filling can be easily done together.By the help of controlling sets, we can change the amount, depth, height, and distance of the fertilization for different operators ac-cording to the size, growing condition and other condition of the tree.This device is capable saving efforts, labor and time, reducing the damage to the roots, fertilizing in a well distributed way.
