This utility model discloses a fabric colorimetric testing device for textile fabric production, relating to the field of fabric colorimetric testing technology. It includes a water tank body with an installation mechanism for fabric colorimetric testing in textile fabric production. The installation mechanism includes an adjustment component and a first support frame connected to the side wall of the water tank body via an opening and closing component. A first electric push rod is fixedly fixed through the upper end of the first support frame, and a mounting bracket is fixed to the telescopic end of the first electric push rod. This utility model uses a motor to drive a rotating disk to rotate, and a connecting shaft pushes a slider to slide on a sliding rod.

This invention relates to a seedling cultivation device and method based on afforestation, and relates to the field of seedling transplanting technology. It includes a mounting frame with symmetrically symmetrically opened holes on the frame housing vertically mounted hydraulic push rods. The lower output end of each hydraulic push rod is slidably connected to a drive box via a slider.
