1results about How to "Growth impact" patented technology

This utility model discloses a crop breeding shading device, applied in the field of crop breeding technology. It includes a fixed frame, with a shading plate bolted inside the frame. The shading plate has a first through hole inside, and a sliding plate slidably connected to the fixed frame is located on the top of the shading plate. By sliding the sliding plate inside the fixed frame, the area where the second and first through holes overlap can be adjusted. This allows for adjustment of the light intensity passing through the second and first through holes when the holes change size during overlap, meeting the breeding needs of different crops and improving practicality. Raising the fixed frame allows support legs to slide inside a fixed cylinder, and the spring force drives a rod to extend from inside the support legs, limiting and fixing the height of the fixed frame. This allows for adjustment of the seed growth space, preventing interference with seedling growth after breeding.
