Description

Instrument for measuring included angle of cotton leaf Technical Field The utility model relates to the technical field of agricultural information acquisition and measurement, in particular to a cotton leaf included angle measuring instrument. Background In cotton planting and breeding research, the included angle between the leaf and the main stem is one of important parameters reflecting cotton plant type structure, illumination utilization efficiency and ventilation and light transmission performance. The accurate measurement of the included angle of the blades is not only beneficial to optimizing the planting density and the cultivation mode, but also can provide scientific basis for cotton variety breeding. The existing mechanical contact type cotton leaf included angle measuring device is mostly attached to a main stem and a leaf through two measuring arms respectively, so that included angle data are obtained, the main stem cannot be effectively clamped due to the fact that manual holding is usually relied on for operation, and the measuring error is large due to the fact that the main stem is easy to shake by hands, shake by plants or reference position deviation of the measuring arms in the measuring process. Disclosure of utility model In order to make up for the defects, the utility model provides the cotton leaf included angle measuring instrument, and aims to solve the problems that the traditional measuring device relies on manual holding to aim at a main stem, is easy to shake and affects the measuring accuracy. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a cotton leaf contained angle measuring apparatu, includes the fixed plate, the inside of fixed plate is seted up flutedly, the inner wall fixedly connected with spring of fixed plate is first, the outer wall fixedly connected with sliding plate of spring is first at the inner wall of recess, the outer wall sliding connection of sliding plate is at the inner wall of recess, the equal fixedly connected with limiting plate of both sides outer wall of sliding plate, the spacing groove has been seted up to the inside of fixed plate, the outer wall sliding connection of limiting plate is at the inner wall of spacing groove, the outer wall fixedly connected with splint of sliding plate, the outer wall fixedly connected with silica gel pad of splint, the outer wall of fixed plate is provided with supporting component.
