Multifunctional capacitance apparatus used for wheat leaf physiological electrical characteristic determination

Abstract

The invention discloses a multifunctional capacitance apparatus used for wheat leaf physiological electrical characteristic determination. A reverse osmosis membrane is sleeved and wound at an air inlet of a cuboid-shaped or cylindrical-shaped box body, the cuboid-shaped or cylindrical-shaped box body is also provided with an air outlet, the air outlet penetrates a cuboid-shaped or cylindrical-shaped housing, besides, the cuboid-shaped or cylindrical-shaped box body is internally provided with a second air intake fan started by a motor, the second air intake fan and the reverse osmosis membrane are both installed on a motor shaft of the motor, and furthermore, the second air intake fan is arranged between the motor and the reverse osmosis membrane. According to the invention, the defects of difficulty in erection between the housing and the box body, damage usually caused to the housing after not-short application period of the housing, difficulty in ensuring erection reliability, and unfavorable influences exerted to performance of a blade clamp due to adhesion of impurity particles to the blade clamp are avoided.

Description

technical field [0001] The invention relates to the technical field of a capacitive device, in particular to a multifunctional capacitive device for measuring the physiological and electrical characteristics of wheat leaves. Background technique [0002] The understanding of foreign scholars on the dielectric properties has begun to take shape, and in-depth exploration has been carried out in many fields. From the initial moisture content affecting the dielectric properties of crops, to the current research on the tissue density, material density, free water and other more detailed aspects of the research object. In short, the dielectric properties of crops vary with water content at different frequencies, and there may be a critical frequency (the capacitance of crops changes most obviously with water content), and the water content of crops is proportional to its dielectric constant. Although the conclusions of many researches and experiments are more or less controversia...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a multifunctional capacitive device for measuring the physiological and electrical characteristics of wheat leaves, which avoids the difficulty of erecting between the shell and the box, and the shell is often used after the service life is not short. Damage occurs, the reliability of erection is difficult to be guaranteed, and foreign particles tend to adhere to the blade holder, which will have a bad impact on the performance of the blade holder.
