The present invention relates to a method of manufacturing a reflector which is installed on a side surface of a vehicle running in an orchard of fruit orchards in which fruit trees are planted so that the reflection film is continuously coated on the ground, The reflective film can be firmly fixed to the ground by the fixing member at the same time as the covering of the reflecting film and the tension film can be firmly fixed to the ground by the fixing member, So that the reflective film can be maximally reflected to the sun by arranging the reflective film in a fully unfolded state. The reflective film coating apparatus for a fruit tree includes a horizontal supply unit having a vertical supply unit having an inlet at an upper end thereof and a discharge port at a rear end thereof communicating with the vertical supply unit, Fixing members to be inserted into the inlet are sequentially stacked in the vertical supply unit and then sequentially moved toward the discharge port in the horizontal supply unit and are arranged so as to be adjustable in width from each other; So that the reflective film wound in the roll type in the longitudinal direction can be coated on the paper sheet. [0033] In addition, Wherein the fixing member is fitted in a releasable manner in the lower direction of the fixing member feeding means, And a fixing member which is connected to the discharge port rear side of the horizontal supply unit and is moved along the horizontal supply unit, is connected to the discharge port through the discharge port And the upper end of the supplied fixing member is struck so that the reflective film coated on the ground is fixed and interlocked with the width of the fixing member feeding means and the reflection film mounting means on both sides And a fixing member hitting means on both sides of which the width is adjusted.본 발명은 과수나무가 식재된 과수원의 과수로에서 주행되는 차량의 측면에 설치되어 반사필름이 지면에 연속으로 피복되게 하여 과일의 하부면에도 일조량이 충분히 공급될 수 있게 하고, 차량에 의해 반사필름이 피복됨으로써 노동력이 절감됨은 물론 키
