Abstract
The invention discloses a sensor for measuring electrical parameters of plant leaves. The sensor consists of a plastic clip, pole pieces, a foam plate and a conducting wire, wherein the foam plate is adhered to the plastic clip, so the clip is prevented from having excessively large clamping force, and the leaves can be enabled to be uniformly stressed; the pole pieces are embedded in foam on the clip and aligned to each other, and the two pole pieces are simultaneously connected with two conducting wires, so that the sensor can be connected with an LCR (liquidity coverage ratio) test instrument. When in use, the two conducting wires of the sensor are connected with a four-terminal test probe 9140 of the LCR test instrument, then the two pole pieces are unfolded to clamp the leaves, measured parameters are set, and corresponding software is used for counting. By adopting the sensor, different electrical parameters of the plant leaves in different thicknesses can be nondestructively measured on line.
Description
Technical field
The present invention relates to a kind of sensor of measuring plant leaf blade electrical quantity, coordinate LCR tester, be applicable to all kinds of electrical quantitys of non-destructive determination plant leaf blade, as electric capacity, resistance, electricity are led etc.
Background technology
In recent years, the electrical property change of existing research and utilization plant tissue reflects water regime, measures plant tissue electrical characteristics and can be divided into damaging and detect and two kinds of Non-Destructive Testings.Damage and detect the general aculeus type that adopts, be used for thick stem culm plant, as corn, Chinese sorghum, fruit etc.; Because organization structure of the plant is comparatively complicated, damage to detect plant is caused to certain destruction, plant is reacted to this by the light of nature, affects measurement result.Non-Destructive Testing relates generally to parallel-plate sensor, take blade as dielectric, is adapted to various crops; During self-control parallel-plate sensor, need to consider two problems, the one, the holding force of sensor is moderate, and the 2nd, the material of pole piece and shape.Aspect holding force, the parallel-plate sensor that existing Non-Destructive Testing relates to, generally the holding force of clip is of moderate size the spring annealing of plastic clip, but the operation of spring annealing, must first spring be heated to proper temperature, insulation certain hour, then Slow cooling, makes structure processed complex.
Summary of the invention
The object of the present invention is to provide a kind of sensor of measuring plant leaf blade electrical quantity, facilitate easy to use in, simplified structure.
In order to solve above technical matters, the concrete technical scheme that the present invention adopts is as follows:
Measure a sensor for plant leaf blade electrical quantity, it is characterized in that comprising: by plastic clip (1), pole plate (3), cystosepiment (2), wire (4), formed; Two cystosepiments (2) are bonded at respectively on two faces that plastic clip (1) bare terminal end contacts with thing to be held, to avoid plastic clip (1) holding force too large, also can guarantee that plant leaf blade to be measured is stressed evenly simultaneously; Two pole plates (3) are embedded in respectively in two cystosepiments (2) of the upper bare terminal end of plastic clip (1) and keep when plastic clip (1) bare terminal end is combined, and the just complete correspondence of two pole plates (3) together; Two pole plates (3) connect a wire (4) separately, for being connected with LCR tester.
Described pole plate (3) is circular pole piece, thereby reduces the edge effect of electrode.
The material of described pole plate (3) is stainless steel.
the present invention has beneficial effect.The present invention, by plastic clip (1) bare terminal end opening and closing, makes the distance between two-plate (3) can realize adjustment flexibly, thereby can measure the plant leaf blade of different-thickness; By two cystosepiments (2), be bonded at respectively on two faces that plastic clip (1) bare terminal end contacts with thing to be held, cystosepiment can make plant leaf blade stressed evenly and holding force not too large, can damaged blade while making to measure, nondestructively every electrical quantity of the plant leaf blade of on-line measurement different-thickness, simplifies the structure.Consider economy and practicality, the present invention selects stainless circular pole piece, and selects circular pole piece can reduce the edge effect of electrode.
